Currently, many architecutres have't taken the standard GENERIC_IOREMAP
way to implement ioremap_prot(), iounmap(), and ioremap_xx(), but make
these functions specifically under each arch's folder. Those cause many
duplicated codes of ioremap() and iounmap().
In this patchset, firstly adapt the hooks io[re|un]map_allowed, then
make use of them to convert those ARCH-es to take GENERIC_IOREMAP method.
With these change, duplicated ioremap/iounmap() code uder ARCH-es are
removed.
This is suggested by Christoph in below discussion:
https://lore.kernel.org/all/Yp7h0Jv6vpgt6xdZ@infradead.org/T/#u
And it's basically further action after arm64 has converted to
GENERIC_IOREMAP way in below patchset.
[PATCH v5 0/6] arm64: Cleanup ioremap() and support ioremap_prot()
https://lore.kernel.org/all/20220607125027.44946-1-wangkefeng.wang@huawei.com/T/#u
And some change of io[re|un]map_allowed() is borrowed from the v3 of
arm64 converting patch.
[PATCH v3 4/6] mm: ioremap: Add arch_ioremap/iounmap()
https://lore.kernel.org/all/20220519082552.117736-5-wangkefeng.wang@huawei.com/T/#u
v1->v2:
Rename io[re|un]map_allowed() to arch_io[re|un]map() and made
some minor changes in patch 1~2 as per Alexander and Kefeng's
suggestions. Accordingly, adjust patches~4~11 because of the renaming
arch_io[re|un]map().
Testing:
It passes the testing on arm64. For other ARCHes, I only tried to pass
build with existing RPMs of cross compiling tools. ARCHes like openrisc,
parisc, don't build because of lack of cross compiling RPMS.

In some architectures, there are ARCH specifici io address mapping
handling when calling ioremap() or ioremap_prot(), e.g, arc, ia64,
openrisc, s390, sh.
In oder to convert them to take GENERIC_IOREMAP method, we need change
the return value of hook ioremap_allowed() and iounmap_allowed().
Meanwhile, rename them to arch_ioremap() and arch_iounmap() to reflect
their current behaviour.
===
arch_ioremap() return a bool,
- IS_ERR means return an error
- NULL means continue to remap
- a non-NULL, non-IS_ERR pointer is returned directly
arch_iounmap() return a bool,
- 0 means continue to vunmap
- error code means skip vunmap and return directly
This is taken from Kefeng's below old patch. Christoph suggested the
return value because he foresaw the doablity of converting to take
GENERIC_IOREMAP on more architectures.
- [PATCH v3 4/6] mm: ioremap: Add arch_ioremap/iounmap()
- https://lore.kernel.org/all/20220519082552.117736-5-wangkefeng.wang@huawei.com/T/#u
While at it, the invocation of arch_ioremap() need be moved to the
beginning of ioremap_prot() because architectures like sh, openrisc,
ia64, need do the ARCH specific io address mapping on the original
physical address. And in the later patch, the address fix up code
in arch_ioremap() also need be done on the original addre on some
architectures.
This is preparation for later patch, no functionality change.

On some architectures, the physical address need be fixed up before
doing mapping, e.g, parisc. And on architectures, e.g arc, the
parameter 'prot' passed into ioremap_prot() need be adjusted too.
In oder to convert them to take GENERIC_IOREMAP method, we need wrap
the address fixing up code and page prot adjusting code into arch_ioremap()
and pass the new address and 'prot' out for ioremap_prot() handling.
This is a preparation patch, no functionality change.

Architectures like xtensa, arc, can be converted to GENERIC_IOREMAP,
to take standard ioremap_prot() and ioremap_xxx() way. But they have
ARCH specific handling for ioremap() method, than standard ioremap()
method.
In oder to convert them to take GENERIC_IOREMAP method, allow these
architecutres to have their own ioremap definition.
This is a preparation patch, no functionality change.

Add hooks arch_ioremap() and arch_iounmap() for arc's special
operation when ioremap_prot() and iounmap(). Meanwhile define and
implement arc's own ioremap() because arc has some special handling
in ioremap() than standard ioremap().

With it, the old ioremap() and iounmap() can be perfectly removed
since they are duplicated with the standard functions.

Add hooks arch_ioremap() and arch_iounmap() for ia64's special
operation when ioremap() and iounmap(), then ioremap_cache() is
converted to use ioremap_prot() from GENERIC_IOREMAP.
The old ioremap_uc() is kept and add its macro definittion.

Add hooks arch_ioremap() and arch_iounmap() for s390's special
operation when ioremap() and iounmap(), then ioremap_[wc|wt]() are
converted to use ioremap_prot() from GENERIC_IOREMAP.

Please avoid the overly long lines.
I also wonder if we just want a common definition with a __weak default
instead of duplicating it in many arch headers.

No need for the else here.

It seems a bit odd to do this in two steps vs just doing the entire
change in the first patch. Any good reason for that?

Do they?
For arc, the arc_uncached_addr_space case can be easily handled by
arch_ioremap, and the xtensa case looks very similar to that.
I'd really like to kill off arch definitions of ioremap going
forward, as they should just be a special case of ioremap_prot
by definition.

Can you write a somewhat better commit message explaining that it
switches to the generic code that has equivalent functionality?
> +#define ioremap_uc(addr, size) ioremap((addr), (size))
This is wrong and hexagon should use the asm-generic version of
ioremap_uc that returns NULL.

Same comment about the commit log (I won't repeat it as it applies
to all conversions).

This code needs to go away, and all very early boot uses of ioremap
need to switch to use early_ioremap insted.

This logic isn't new in the patch, but it could really use a comment
as it is rather non-obvious.

You need to install the gcc-hppa64-linux-gnu and gcc-hppa-linux-gnu DEBs/RPMs.
As COMPILER you probably only need "gcc" (or leave COMPILER empty/unset).
Then run "make ARCH=parisc64" (64bit) or "make ARCH=parisc" (32bit).
The Makefile should automatically detect your compiler..

Please don't just say you need to change the return value. Explain why.
And why does it need a name change ? The new name suggests that what was
simply a check function becomes now a function doing the job. Is that
the intention ?

It is not a bool. A bool is either true or false.

Same here, not a bool either.

No functionnal change, really ?

Is it really the best approach ? Wouldn't it be better to have helpers
to do that, those helpers being called by the ioremap_prot(), instead of
doing it inside the arch_ioremap() function ?

I see nothing related to the preparation patches. Could this have been
converted without all previous patches ? In that case I think this one
should go in the begining of the series, it would help see which
architectecture really needs the changes to the generic parts.

Yes, makes sense. Basically we fake MMIO addresses because the s390
architecture doesn't have MMIO as a concept. That is until the PCI MIO
instructions introduced pseudo-MMIO though only for specific PCI
load/store instructions. Without those PCI BAR spaces as well as config
space is accessed with so called function handles. As these are a bad
fit for Linux' MMIO based APIs we create fake MMIO addresses (called
address cookies) that encode an index into the zpci_iomap_start[] which
can be decoded by our implementation of ioread*/iowrite*().
I don't think this is the right place to describe this overall scheme
in detail but maybe we can leave a a good bread crumb. Maybe something
like below?
/*
* When PCI MIO instructions are unavailable the "physical" address encodes
* a hint for accessing the PCI memory space it represents. Just pass it
* unchanged such that ioread/iowrite can decode it.

Sorry I missed this mail until now and will still need a bit of time to
review and test the code as this is indeed pretty special on s390. From
a first glance this does look like a nice simplification.
Just out of curiosity, I wonder why get_maintainers.pl didn't add me
nor Gerald for direct CC despite the bulk of the changes affecting
arch/s390/pci/*.

Do you mean changing it like this? It's fine to me if I get it
correctly.
ioaddr = arch_ioremap(phys_addr, size, prot);
if (IS_ERR(ioaddr))
return NULL;
if (ioaddr)
return ioaddr;

The 1st paragraph and the sentence 'In oder to convert them to take
GENERIC_IOREMAP method' tell the reason, no?

Yes, it's not a simple checking any more. It could do io address mapping
inside arch_ioremap(), and could modify the passed in 'phys_addr' and
'prot' in patch 2. The ioremap_allowed() isn't appropriate to reflect
those.

You mean the new arch_ioremap() owning different definition or the
invocation of arch_ioremap() moved up is functional change? Now I am
not sure about the latter one, may need update my knowledge base.

I will merge patch 1~2 or 1~3 into patch 1. Earlier, I wrote the reason
as below paragraph in cover letter of v1 post. Now it seems not so hard
to tell and understand.
====
For patch 1~3, I don't merge them because I made them in different
rounds of changing. And splitting them makes me easily describe the
intention and make review easier. I can merge them after v1 reviewing
if anyone thinks they should be merged.

This is suggested too by Alexander during his v1 reviewing. I tried, but
feel the current way taken in this patchset is better. Because not all
architecutres need the address fix up, only parisc, and only few need
adjust the 'prot'. Introducing other helpers seems too much, that only
increases the complexity of of ioremap() and the generic GENERIC_IOREMAP
method for people to understand and take.

I am worried it will impact ioremap_prot(). Arc has selected
HAVE_IOREMAP_PROT in Kconfig. Putting arc_uncached_addr_space() calling
into arch_ioremap() will change ioremap_prot(), right?
And I have the same about xtensa. You can see ioremap() and
ioremap_cache() will return different value since they take
XCHAL_KIO_BYPASS_VADDR and XCHAL_KIO_CACHED_VADDR differently. I haven't
figured out a way to handle them in arch_ioremap() differently.
static inline void __iomem *ioremap(unsigned long offset, unsigned long size)
{
if (offset >= XCHAL_KIO_PADDR
&& offset - XCHAL_KIO_PADDR < XCHAL_KIO_SIZE)
return (void*)(offset-XCHAL_KIO_PADDR+XCHAL_KIO_BYPASS_VADDR);
else
return xtensa_ioremap_nocache(offset, size);
}
static inline void __iomem *ioremap_cache(unsigned long offset,
unsigned long size)
{
if (offset >= XCHAL_KIO_PADDR
&& offset - XCHAL_KIO_PADDR < XCHAL_KIO_SIZE)
return (void*)(offset-XCHAL_KIO_PADDR+XCHAL_KIO_CACHED_VADDR);
else
return xtensa_ioremap_cache(offset, size);
}

Both indeed. I understand that this first step is not changing much to
the logic, but I think the simple fact to change the arguments and name
are some how a functionnal change.

I can't understand. Why is it difficult to do something like:
#ifndef ioremap_adjust_prot
static inline unsigned long ioremap_adjust_prot(unsigned long flags)
{
return flags;
}
#endif
Then for arc you do
static inline unsigned long ioremap_adjust_prot(unsigned long flags)
{
return pgprot_val(pgprot_noncached(__pgprot(flags)));
}
#define ioremap_adjust_prot ioremap_adjust_prot
By the way, could be a good opportunity to change ioremap_prot() flags
type from unsigned long to pgprot_t

As Christoph suggested this might be a good opportunity to add a
comment for this branch.
One other nitpick. The return value doesn't really matter here since
anything != NULL turns iounmap() into a no-op so this looks correct but
semantically I think returning -EINVAL wrongly suggests that addr was
invalid. Maybe -ENXIO would be better at conveying that there is
nothing to unmap.
Looking at your patch 1 another idea would be to have 3 kinds of return
values for arch_iounmap() too e.g.:
arch_iounmap() return an __iomem pointer
- IS_ERR means skip vunmap and return directly
- NULL means continue to vunmap
- a non-NULL, non-IS_ERR pointer has been unmapped successfully
Then we would simply return addr in case of
!static_branch_likely(&have_mio) and NULL otherwise.
What do you think? Either way no strong opinion on my side,
functionally it makes no difference.

Apart from the above nitpicks and suggestion this looks good to me.
I did also test this with and without PCI MIO support including use of
PCI MIO instructions in user-space (added in rdma-core v40).

My thinking is we have four things to do in the added hookers.
1) check if we should do ioremap on ARCHes. If not, return NULL from
ioremap_prot();
2) handling the mapping io address specifically on ARCHes, e.g arc,
ia64, s390;
3) the original physical address passed into ioremap_prot() need be
fixed up, e.g arc;
4) the 'prot' passed into ioremap_prot() need be adjusted, e.g on arc
and xtensa.
With Kefeng's patches, the case 1) is handled with introduced
ioremap_allowed()/iounmap_allowed(). In this patchset, what I do is
rename the hooks as arch_ioremap() and arch_iounmap(), then put case 1),
2), 3), 4) handling into arch_ioremap(). Adding helpers to cover each
case is not difficult from my side. I worry that as time goes by, those
several hooks my cause issue, e.g if a new adjustment need be done,
should we introduce a new helper or make do with the existed hook; how
When I investigated this, one arch_ioremap() looks not complicated
since not all ARCHes need cover all above 4 cases. That's why I finally
choose one hook. I am open to new idea, please let me know if we should
change it to introduce several different helpers.

Tend to agree, I will give it a shot.

I rephrase the log as below, it's OK to you? Or please help check and
tell what I need to improve to better explain the reason.
====
The current io[re|un]map_allowed() hooks are used to check if the
io[re|un]map() actions are qualified to proceed when taking
GENERIC_IOREMAP way to do ioremap()/iounmap(). Otherwise io[re|un]map()
will return NULL.
On some architectures like arc, ia64, openris, s390, sh, there are
ARCH specific io address mapping to translate the passed in physical
address to io address when calling ioremap(). In order to convert
these architectures to take GENERIC_IOREMAP way to ioremap(), we need
change the return value of hook ioremap_allowed() and iounmap_allowed().
With the change, we can move the architecture specific io address
mapping into ioremap_allowed() hook, and give the mapped io address
out to let ioremap_prot() return it. While at it, rename the hooks to
arch_ioremap() and arch_iounmap() to reflect their new behaviour.

OK, I thought the function interface change is not related to functional
change. I will remove the 'no functionality change' sentence to avoid
misleading. Thanks.

A new idea that would have my preference would be to do just like we did
with arch_get_unmapped_area(). Look at
https://elixir.bootlin.com/linux/v6.0-rc1/source/arch/powerpc/mm/book3s64/slice.c#L638
and https://elixir.bootlin.com/linux/v6.0-rc1/source/mm/mmap.c#L2131
Instead of having the generic that calls the arch specific, make it the
other way round, have the arch specific call the generic after doing its
specialties.

I think you also need to summarise the change itself.
If the success/fail return actually changes then you really
need to change something so the compiler errors unchanged code.
Otherwise it is a complete recipe for disaster.

It would make more sense if the return values were described
from the prospective of an architecture, not the caller.
I.e true - unmapped, false - not supported, etc.

It seems to me arch_ioremap() could simply return an address
or an error. Then IOMEM_ERR_PTR(-ENOSYS) if the architecture
does not support it reads much better than the cryptic NULL.
Probably arch_iounmap() returning error would look better too,
though not sure about that.
Thanks!

Yes, sounds reasonable to me, thanks.
While ChristopheL suggested to take another way. Please see below link.
I will reply to Christophe to discuss that.
https://lore.kernel.org/all/8df89136-a7f2-9b66-d522-a4fb9860bf22@csgroup.eu/T/#u
If the current arch_ioremap() way is taken, I will change the
description as you said.

I may not follow. Returning NULL means arch_ioremap() doesn't give out a
mapped address and doesn't encounter wrong thing. NULL is a little
twisting, maybe '0' is better?

Don't follow either. arch_iounmap() is returning error now.

This sounds good. I made a draft patch to change code in generic code
part, just showing what it looks like.
Both arch_ioremap() way and the arch sepcific call the generic way look
good to me. Just it will take less effort for me to continue the
arch_ioremap() way. I would like to hear Christoph's opinion since he
introduced the GENERIC_IOREMAP method and suggested the earlier
arch_ioremap() way and change in this patchset.

Thanks for looking into this and sorry for late response.
I am not sure if I follow you. In this patch, I just rename the old
ioremap_allowed() to arch_ioremap(), and change its return value. Except
of arm64 which has taken GENERIC_IOREMAP way to provide
ioremap_allowed(), no other ARCHes are affected yet. This is what have
been changed. Could you be more specific what I should add?
Or are you suggesting words like below sentences need be added to patch
log?
If the success/fail return actually changes then you really
need to change something so the compiler errors unchanged code.
Otherwise it is a complete recipe for disaster.
Thanks

OK, I will rephrase like below. Please check if it's OK.
==
By taking GENERIC_IOREMAP method, the generic ioremap_prot() and
iounmap() are visible and available to arch. Arch only needs to
provide implementation of arch_ioremap() or arch_iounmap() if there's
arch specific handling needed in its ioremap() or iounmap(). This
change will simplify implementation by removing duplicated codes with
generic ioremap() and iounma(), and has the equivalent functioality
as before.

I don't follow. Do you mean the function verion, but not a macro? Or
define it like below?
#define ioremap_uc(addr, size) \
ioremap_prot((addr), (size), _PAGE_IOREMAP)

You are right. Hexagon basically has the same implementation as standard
ioremap and iounmap code. I will move this at the beginning of patch
series in next round of post. Thanks for point this out.

Makes sense. On openrisc, the thing is I didn't find one place where
ioremap() is called in arch code. I can cut the early ioremap out and
wrap into a separate early_ioremap() function, however I don't know
where to put it. Not sure if I miss anything or openrisc doesn't really
need early ioremap.

This seems to cause a compilation issue when building virt_defconig:
CC kernel/irq/generic-chip.o
In file included from ./include/asm-generic/pgtable-nopud.h:7,
from ./include/asm-generic/pgtable-nopmd.h:7,
from ./arch/openrisc/include/asm/pgtable.h:24,

./include/asm-generic/pgtable-nop4d.h:9:18: error: unknown type name 'pgd_t'
9 | typedef struct { pgd_t pgd; } p4d_t;
| ^~~~~
It works if we swap the order arround:
+#include <asm/pgalloc.h>
+#include <asm/pgtable.h>
Otherwise we need to add an asm/page.h include to asm/pgtable.h (which is more
correct) but means you would touch more files.

Other than that compiler issue, I fixed it and test booted this and it works
well.

Hi,
I don't know of any early_ioremap usage either in openrisc, maybe some drivers
use it? However, we do not initialize any early_ioremap infrastructure in
openrisc so that may cause issues if it is used.
We can try to remove it all. I tested these below additional changes and they
work, if you want to add them we can see if kbuild robots pick anything up.

The variable mem_init_done indicates if mem_init() is called or not.
Driver should only initialize after mem_init(). With my understanding,
the early ioremap is only needed by arch code.

Very helpful information. Then I will remove the !mem_init_done part
code as you listed below, let's see how test robots react. Thanks a lot.

early_ioremap() is not that easy to use. I don't know in this particular
openrisc context, but in powerpc we have many places that use ioremap()
very early.
Three years ago we implemented EARLY_IOREMAP, commit d538aadc2718
("powerpc/ioremap: warn on early use of ioremap()") added a warning to
identify all places using ioremap() early with the target being to get
rid of early usage of ioremap. But it turned that using early_ioremap()
is not that easy.
The problem with early_ioremap() is that it installs ephemeral mappings
that must be freed before the end of init. Most early uses of ioremap()
in powerpc are to install mappings that will last for life.
If we could have something that works like memblock_alloc() and allows
to keep the allocation forever, then it would be a lot easier to use
early_ioremap() and we could get rid of the early handling of ioremap()
in powerpc.

I finally installed below RPM packages and run command to reproduce
the build errors. Thanks for your help, Helge.

The below draft patch can fix all build errors. There are some symbol
declaration or defination conflict among asm-generic/io.h,
asm-generic/iomap.h, asm-generic/pci-iomap.h and asm/io.h. Some of them
may need be taken out to be an independent patch since it could be a
generic issue if enable GENERIC_IOREMAP. I saw the build error on superH
too.

I agree with you, The returned -EINVAL does cause confusion.
I checked all ARCHes related in this patchset, we only do the arch
specific address filtering (or address checking), then call vunmap().
Seems no error case or error handling in iounmap(). I'm thinking if
we should make the return value as boolean value. Ture indicates
address checking passed, false indicates not passed.

I run below script again, it does print you and Gerald's name in the

Yeah, you are right, will put them under CONFIG_MMU.
I thought making GENERIC_IOREMAP depend MMU in Kconfig will contain
that. But people can manually set the Kconfig item freely. Thanks for
pointing it out.

I can only find binutils-sh-linux-gnu on fedora, but no gcc-sh-linux-gnu
for cross compiling superh kernel. So I tried above steps, but it failed
as below, any suggestion I can fix it to proceed for reproducing the

Hi Baoquan,
Sorry for the inconvenience, /root/0day/gcc-12.1.0-nolibc/sh4-linux/bin
/sh4-linux-gcc is for x86_64 machine, as the name "ampere-mtsnow-altra",
is it a arm server?
the tool for arm64 can be downloaded from
https://cdn.kernel.org/pub/tools/crosstool/files/bin/arm64/12.1.0/
Best Regards,
Rong Chen

Oops, I thought the cross compilig can be done on any platform. Since
I need test arm64 patch in this patchset, so didn't get x86 system to
reproduce. Didn't realize lkp has an assumption. I will get a x86 system
to test this.
Thanks for your help!

I finally find gcc-sh-linux-gnu and its dependency on rpmfind.net, and
succeeded to reproduce the building failure.
isl-0.16.1-13
cross-gcc-common
gcc-sh-linux-gnu
Based on previous fixing patch for parisc, below draft patch can fix all
reported building issues on sh.

I will make another round change and post. Since Christoph doesn't
reply, I would like to continue with the existing
arch_ioremap/arch_iounmap() hooks way if you don't have strong opinion
on the new idea to reintroduce ioremap().

I still dislike you approach with the architectures modifying local vars
by reference, and as you said earlier I'm not the only one : "This is
suggested too by Alexander during his v1 reviewing".
So I'd really prefer you to reconsider your approach and avoid passign
pointers to local vars to architecture helpers.

Alexander suggested several helpers, as I have explained earlier, that
will cause at least four helpers currently. And could be more later if
new change is introduced. And the address fixup and prot modifcation
are related in few architecutures. Adding all of them is is not so
necessary.

If only passing pointers to local vars is disliked, I can explain why I
did so. Let me take arch_ioremap() of a64 as example. I can derefence
pointer in arch_ioremap() to avoid assigning pointers to local vars.
Please see below two version for comparing, and please tell which one is
better.
To me, assigning pointers to local vars make code simple and clean,
honestly.
******
The version in which pointers assigned to local vars looks like below.
The old phys_addr is passed in, the assigning can decrease changed line.

The version in which pointer is dereferenced directly in place. Then
more lines of code are involved. And some pointer derefencing takes

Well, for me it looks ood, not intellectually natural.
If I understand correctly, you do
ioremap()
--> Call arch_ioremap()
--> If the arch doesn't want to handle ioremap itself, it returns NULL
--> Then you fallback on generic handling.
The arch may say "I don't want to handle it", but at the same time it
blindly modifies the parameters so that the generic handling is not
exacly the generic handling.
Not easy to follow for the reader. Do you have any exemple in the kernel
that works more or less with the same approach ?
What I propose is
Arch specific ioremap()
--> do proper preparation
--> call generic_ioremap()
And the generic fallback implementation when the arch doesn't have a
specific ioremap()
__weak ioremap()
--> call generic_ioremap().
The above looks a lot more natural and easier to follow, it is clear for
the reader which function does what.

No, it's not like that.
Arch_ioremap() provides a place where arch specific handling can be
done. While it doesn't mean arch has to do all of the follow four
things. From the current change I made listed as below, arch_ioremap()
in each architecture is quite simple to do one or two things.
People only need to provide arch_ioremap() if needed, or do not provide
arch_ioremap() at all if not needed. No such thing could hapen like you
said that arch don't want to handle, but it blindly modifes the parameter.
arm64:
- address checking;
hexagon: removes the ioremap() directly since it has the same code as standard;
- N/A
arc:
- address checking
- modify the prot flag;
ia64:
- specific io address mapping
openrisc: removes ioremap() directly after its early ioremap is cleared away;
- N/A
parisc:
- physical address fixup
- address checking;
s390:
- specific io address mapping
sh:
- specific io address mapping
xtensa:
- address checking;
Four optional things could be done in arch_ioremap():
1) check if we should do ioremap on ARCHes. If not, return NULL from
ioremap_prot();
2) handling the mapping io address specifically on ARCHes, e.g arc,
ia64, s390;
3) the original physical address passed into ioremap_prot() need be
fixed up, e.g arc;
4) the 'prot' passed into ioremap_prot() need be adjusted, e.g on arc
and xtensa.

Hmm, __weak is not suggested any more in kernel. Please see below
thread.
[PATCH] kexec_file: Drop weak attribute from arch_kexec_apply_relocations[_add]
https://lore.kernel.org/all/20220518181828.645877-1-naveen.n.rao@linux.vnet.ibm.com/T/#u
So with arch_ioremap() hook, now in each architecture it is:
arch_ioremap() is provided and called
or
no hookd is needed at all in arch
It's simpler, isn't it?

Before, there's only arm64 taking GENERIC_IOREMAP way and having
arch_ioremap() as an exmaple. Now after this patchset, there are so many
architectures taking the way, it's very easy to refer to and study,
right?
