This patch-set reworks the kmap_atomic API to be a stack based, instead of
static slot based. Some might remember this from last year, some not ;-)
The advantage is that you no longer need to worry about KM_foo, the
disadvantage is that kmap_atomic/kunmap_atomic now needs to be strictly
nested (CONFIG_HIGHMEM_DEBUG should complain in case its not) -- and of
course its a big massive patch changing a widely used API.
The patch-set is currently based on tip/master as of today, and compile
tested on: i386-all{mod,yes}config, mips-yosemite_defconfig,
sparc-sparc32_defconfig, powerpc-ppc6xx_defconfig, and some arm config.
(Sorry dhowells, I again couldn't find frv/mn10300 compilers)
Boot tested with i386-defconfig on kvm.
Since its a rather large set, and somewhat tedious to rebase, I wanted to
ask how to go about getting this merged?

Keep the current interface but ignore the KM_type and use a stack
based approach.

[-- Attachment #1: kmap-frv.patch --]
[-- Type: text/plain, Size: 6305 bytes --]
Out-of-line the kmap_atomic implementation since the dynamic type
destroys all the constant value reduction previously used.
Also, remove the first 4 primary maps, since those are used by the
architecture for special purposes, mostly through direct assembly, but
also through the __kmap_atomic_primary() interface.

Do the bulk of the km_type and KM_type removement by script.
git grep -l -e km_type -e KM_ | grep -v xfs | while read file;
do
quilt add $file;
sed -i -e 's/,[[:space:]]*enum km_type type[[:space:]]*//g' \
-e 's/,[[:space:]]*KM_[[:digit:][:upper:]_]*[[:space:]]*//g' \
$file;
done

[-- Attachment #1: kmap-pte_nest.patch --]
[-- Type: text/plain, Size: 22745 bytes --]
Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.

[-- Attachment #1: kmap-pte_nest.patch --]
[-- Type: text/plain, Size: 22970 bytes --]
Since we no longer need to provide KM_type, the whole pte_*map_nested()
API is now redundant, remove it.

Nice. That fixes the "use of irq-only slots from interrupts-on
context" bugs which people keep adding.
We don't have any checks in there for the stack overflowing?
Did you add every runtime check you could possibly think of?
kmap_atomic_idx_push() and pop() don't have much in there. It'd be
good to lard it up with runtime checks for at least a few weeks.

Well, there's that monster conversion patch. How's about you
temporarily do
#define kmap_atomic(x, arg...) __kmap_atomic(x)
so for a while, both kmap_atomic(a, KM_foo) and kmap_atomic(a) are
turned into __kmap_atomic(a). Once all the dust has settled, pull that
out again?

Nice. That fixes the "use of irq-only slots from interrupts-on
context" bugs which people keep adding.
We don't have any checks in there for the stack overflowing?
Did you add every runtime check you could possibly think of?
kmap_atomic_idx_push() and pop() don't have much in there. It'd be
good to lard it up with runtime checks for at least a few weeks.

Well, there's that monster conversion patch. How's about you
temporarily do
#define kmap_atomic(x, arg...) __kmap_atomic(x)
so for a while, both kmap_atomic(a, KM_foo) and kmap_atomic(a) are
turned into __kmap_atomic(a). Once all the dust has settled, pull that
out again?

Ah, I should add a:
WARN_ON_ONCE(in_irq() && !irqs_disabled());
like check to ensure people don't use kmap_atomic() in nestable IRQ
contexts (nestable IRQ context is bad anyway) the old debug code I
deleted did something similar.
> We don't have any checks in there for the stack overflowing?
+#ifdef CONFIG_DEBUG_HIGHMEM
+ BUG_ON(idx > KM_TYPE_NR);
+#endif
Seems to be that.

Right, so I currently have:
- stack size check in push/pop
- proper nesting check in pop (verifies that the vaddr you try to
unmap is indeed the top most on the stack)
Aside from the proposed no irq-nesting thing to avoid unbounded
recursion I can't really come up with more creative abuse.

Ah, that's a nifty trick, let me try that.

I may don't understand anything... Is irq already disabled ?
And Is it documented that kmap_atomic shouln't be used under NMI or something
special interrupts ?
Thanks,

In particular, we actually do use kmap_atomic from NMI context ;-)
It only relies on preempt_disable(), which for now is implied by
pagefault_disable(), if at some point those get split kmap_atomic will
need to do both (currently only PREEMPT_RT splits it, but then that has
a totally different kmap implementation too).
