[-- Attachment #1: cpumask:add-for_each_cpu_mask_and.patch --]
[-- Type: text/plain, Size: 3824 bytes --]
Add for_each_cpu_mask_and() function to eliminate need for a common use
of a temporary cpumask_t variable. When the following procedure is being
used:
funcproto(const cpumask_t *mask, ...)
{
cpumask_t temp;
cpus_and(temp, mask, cpu_online_map);
for_each_cpu_mask(cpu, temp)
...
It then becomes:
funcproto(cpumask_t *mask, ...)
{
for_each_cpu_mask_and(cpu, *mask, cpu_online_map)
...
... eliminating the need for the temp cpumask.
Applies to linux-2.6.tip/master.

[-- Attachment #1: x86:modify-send_IPI-API.patch --]
[-- Type: text/plain, Size: 53833 bytes --]
Change genapic interfaces to accept cpumask_t pointers where possible.
Modify external callers to use cpumask_t pointers in function calls.
Create new send_IPI_mask_allbutself which is the same as the
send_IPI_mask functions but removes smp_processor_id() from list.
This removes another common need for a temporary cpumask_t variable.
Functions that used a temp cpumask_t variable for:
cpumask_t allbutme = cpu_online_map;
cpu_clear(smp_processor_id(), allbutme);
if (!cpus_empty(allbutme))
...
becomes:
if (!cpus_equal(cpu_online_map, cpumask_of_cpu(cpu)))
...
Other minor code optimizations (like using cpus_clear instead of
CPU_MASK_NONE, etc.)
Applies to linux-2.6.tip/master.

Each SMP arch defines these themselves. Move them to a central
location.
Two twists:
1) Some archs set possible_map to all 1, so we add a
CONFIG_INIT_ALL_POSSIBLE for this rather than break them.
2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
Those archs simply have phys_cpu_present_map replaced everywhere.

cpumask: centralize cpu_online_map and cpu_possible_map
From: Rusty Russell <rusty@rustcorp.com.au>
Each SMP arch defines these themselves. Move them to a central
location.
Two twists:
1) Some archs set possible_map to all 1, so we add a
CONFIG_INIT_ALL_POSSIBLE for this rather than break them.
2) mips and sparc32 '#define cpu_possible_map phys_cpu_present_map'.
Those archs simply have phys_cpu_present_map replaced everywhere.

Seems like this has been here forever, but I can't see why:
find_first_bit and find_next_bit both return >= NR_CPUS on failure.

[-- Attachment #1: cpumask:add-struct-cpumask.patch --]
[-- Type: text/plain, Size: 20071 bytes --]
We want to move cpumasks off the stack: no local decls, no passing by
copy. We also don't want to allow assignment of them, so we can later
partially allocate them (ie. not all NR_CPUS bits).
Unfortunately, all the cpus_* functions are written perversely to take
cpumask_t not cpumask_t *; although they are in fact wrapper macros.
This sets a bad example. Also, we want to eventually make cpumasks an
undefined struct, so we can catch on-stack usage with a compile error.
So we create a 'struct cpumask', typedef cpumask_t to it during the
transition, and cleanup all the cpumask operators to be normal
functions (cpus_ -> cpumask_). Note that two functions already use
variants of the new names: they are fixed in the next patch.

[-- Attachment #1: cpumask:convert-few-difficult-cpumask_t-users.patch --]
[-- Type: text/plain, Size: 12342 bytes --]
We want to move cpumasks off the stack: no local decls, no passing by
copy.
Most cpumask functions started with cpus_: these have been replaced by
cpumask_ ones which take struct cpumask pointers as expected, and macro
stubs used for the transition.
These four functions don't have good replacement names; fortunately
they're rarely used, so we just change them over.

Since cpumasks are to become pointers to undefined structs, we need to
replace assignments. Also, dynamically allocated ones will eventually
be nr_cpu_ids bits (<= NR_CPUS), so assignment is a definite no-no.

We want to move cpumasks off the stack: no local decls, no passing by
copy. Linus suggested we use the array-or-pointer trick for on-stack
vars; we introduce a new cpumask_var_t for this.
Rather than pick an arbitrary limit, I chose a new config option so
arch maintainers can decide where their threshold is.

Currently we have NR_CPUS, which is 1 on UP, and CONFIG_NR_CPUS on
SMP. If we make CONFIG_NR_CPUS always valid (and always 1 on !SMP),
we can skip the middleman.
This also allows us to find and check all the remaining NR_CPUS users.

nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers;
ie. the variable version of NR_CPUS.
This makes is valid in all configs, including UP.

[-- Type: text/plain, Size: 2436 bytes --]
When nr_cpu_ids is set to CONFIG_NR_CPUS then references to nr_cpu_ids
will return the maximum index of the configured NR_CPUS (+1) instead
of the maximum index of the possible number of cpus (+1). This results
in extra unused memory being allocated by functions that are setting up
arrays of structs to keep track of per cpu items.
Since we do want to keep the ability to use constants for the cpu bit
operators on smaller systems (which are generally much faster assembler
ops), we introduce a separate "nr_cpumask_bits" to replace "nr_cpu_ids"
only for the inline assembly ops. This will be a constant when
CONFIG_CPUMASK_OFFSTACK is undefined and a variable when it is defined.
Thus "nr_cpu_ids" reverts back to being a variable representing the
maximum possible cpu (+1), except in the non-SMP case where it is a
constant value of 1. The relationship between the related variables
and constants is: (1 <= nr_cpu_ids <= nr_cpumask_bits <= NR_CPUS).

In fact, all cpumask ops will only be valid (in general) for bit
numbers < nr_cpu_ids. So use that instead of NR_CPUS in various
places.

Percpu areas are only allocated for possible cpus. In general, you
shouldn't access random cpu's percpu areas: you're corrupting memory.

nr_cpu_ids is the (badly named) runtime limit on possible CPU numbers;
ie. the variable version of NR_CPUS.
If we use this in *all* the cpu ops it simplifies the API, and will
be possible to allocate cpumasks of the minimal length at runtime.

[-- Type: text/plain, Size: 1965 bytes --]
This deprecates cpumask_of_cpu(), which returns a cpumask_t
(cpumask_of() returns a const pointer, instead).

We want to wean people off handing around cpumask_t's, and have them
pass by pointer instead. This does for_each_cpu_mask().
We immediately convert core files who were doing
"for_each_cpu_mask(... *mask)" since this is clearer.

any_online_cpu() is a good name, but it takes a cpumask_t, not a
pointer.

Hmm, that's strange. It might be the way quilt mail gathers everything up
into mbox format. I'll experiment a little bit to see what's causing it.
(This is the first time I've used the From: line as well as subject lines
w/o Subject: preceeding them.)
Thanks,
Mike

There's a common case where we want any online cpu except a particular
one. This creates a helper to do that, otherwise we need a temp var
and cpumask_andnot().

Using lots of allocs rather than one big alloc is less efficient, but
who cares for this setup function?

There are times when we really want a static cpumask. Yet we don't
want to expose the struct cpumask definition, to avoid casual on-stack
usage and assignment.
So this macro allows you to do DECLARE_BITMAP(map, CONFIG_NR_CPUS); then use
to_cpumask() to turn it into a cpumask as needed.
Ugly? Yes, but as we move to fewer static cpumasks these calls vanish.

Since we are moving to const cpumask pointers for the maps, we need a
way to legitimately access them. Simple accessors work well.

In order to hide the definition of struct cpumask, we need to expose
only pointers. Plus, it fits the new API far better to have pointers.
This deprecates the old _map versions, and defines them in terms of the
_mask versions. It also centralizes the definitions (finally!).

This bit seems to be the reason why linux-next isn't building for ia64
(tag next-20081029
and next-20081030). With this error:
> CC arch/ia64/kernel/asm-offsets.s

Fix is trivial ... delete the declaration of cpu_online_map from

Instead of CPU_MASK_ALL_PTR and the SMP-only cpu_mask_all, this makes
cpu_all_mask and cpu_none_mask which are const cpumask pointers which
always exist.

cpumask.h is pretty chaotic. Now we've replaced most of it, let's
group things together a bit better.

It's useful to check that no one is accessing > nr_cpumask_bits for
cpumasks. This also allows you to turn on CONFIG_CPUMASKS_OFFSTACK
even for smaller CONFIG_NR_CPUS.

[-- Attachment #1: cpumask:smp_call_function_many.patch --]
[-- Type: text/plain, Size: 10623 bytes --]
Transition from cpumask_t-taking smp_call_function_mask() to a new
smp_call_function_many() which takes a struct cpumask *.
(Naming is inspired by smp_call_function_single).
Note that the new one returns void: the old one couldn't fail either
unless there was a logic bug.

Use the accessors rather than frobbing bits directly. Most of this is
in arch code I haven't even compiled, but it is mostly straightforward.

OK, FYI this one isn't for this merge window: I'll be splitting it and sending
it via the various arch maintainers.
Also, I think a \n got lost, looking at the subject :)
Cheers,

1) The #ifdef CONFIG_HOTPLUG_CPU seems unnecessary these days.
2) The loop can simply skip over offline cpus, rather than creating a tmp mask.
3) set_mask is set to either a single cpu or all online cpus in a policy.
Since it's just used for set_cpus_allowed(), any offline cpus in a policy
don't matter, so we can just use cpumask_of_cpu() or the policy->cpus.

Note that this cleanup stands alone; it's just that I read this code I
couldn't help but tidy it up.
Ingo: do you just want to put this in your normal tree for sending to Linus?

hm, cpufreq stuff belongs into davej's tree.
i skipped #34 and #35 for now, we can live without them, correct?

Definitely, they were tacked on and don't belong with the others.

If those patches are dependant upon the others, I can live with them
going through another tree. There's nothing pending for speedstep-centrino
in cpufreq anyway.

ok - although the cleanups Rusty did look independent to me. We can
just keep it in mind for the future, the whole topic is complex enough
already as-is.

okay, i've picked up these patches into tip/cpus4096-v2 and started
testing them.
I fixed the From: line oddities - please holler if they are wrong
anywhere, we can still rebase this.
Note, i've merged this to _after_ the huge arch/x86/include/asm/ headers
move which we sent a pull request for earlier today - this will simplify
logistics.
( I also fixed up a handful of obvious style problems in various places
- please be more careful about comment structure, whitespaces, etc. -
they just distract from general review and hurt the merits of your
patches. )
I also added "Impact:" lines to every commit - a one-line summary of the
expected outcome of the change. (Please double-check those impact lines
- if you see anything odd it means that i missed some detail in the
commit - that will need to be fixed if it happens.)
I've just completed the first basic step of testing: i did 68 kernel
builds to test bisectability: all 34 commit point builds fine on both
64-bit and 32-bit as well. (This took some time as almost every commit
touches cpumask.h, forcing a full kernel rebuild.)

I found two of them and had resubmitted them, but perhaps that didn't take
either?

I ran all the patches through checkpatches, the only complaints were
about unavoidable items (like we had to use NR_CPUS or we had to introduce
two new typedefs). Everything else was error and warning free...?

Ok, thanks! I'll check them out.

Yes, my regression build for allyesconfig took about 11 hours.

Ok, thanks. I suspect quilt mail is handling things incorrectly (I am
using a slightly older version (0.46 vs. 0.47) [the later removed
"remove" which I found handier than "revert".] I'll put checking this
out on my 'todo' list.
Thanks,
Mike

i suspect it's due to:
01b8bd9: sched: cpumask: get rid of boutique sched.c allocations, use cpumask_va
note, CONFIG_MAXSMP is set in the .config, so this is with the dynamic
cpumask_t.

Thomas has started a -tip cross-build test, and there's massive
cross-build failures as well due to the cpumask changes:
http://www.tglx.de/autoqa-cgi/index?run=140&tree=8
Run 140: 11 of 19 OK
8 architecture configs out of 19 fail to build, 7 of which failures is
this patchset's fault:

Yep. This is the big one I dropped. There are a few others; Mike is just
porting the changes across to your tree now.
Cheers,

Hi Ingo,
It would seem easier to back out previous patches and apply the replacements.
Does this work for you?
Thanks,
Mike

no, it does not work fine. As i said, i reworked various small bits
along the way of reviewing and integrating them, under the obvious
assumption that you submitted the latest and greatest. I spent hours
testing every single step as well. If you cannot get your workflow right
then we cannot have this stuff in v2.6.28.
So ... please send append-only changes against tip/cpus4096-v2. We can
squash/backmerge any bits to keep it all clean, but all changes have to
be fully visible and fully reviewed from now on, because time is running
short.
Ingo

Indeed, though to be honest it's been easier to do the fixes in linux-next.
Here's the interdiff; it's not too bad (you already reverted the
arch-destroying config changes).
Summary:
1) Alpha defines cpu_possible_map to cpu_present_map: this isn't possible
under centralization, so just manipulate both together.
2) IA64, cris and m32r gratuitously re-declared cpu_possible_map; remove.
3) PowerPC Cell used __cpu_setall in a questionable way.
Arnd approved this version.
4) That also leads to weakening the BUG_ON() to WARN_ON_ONCE() for
CONFIG_DEBUG_PER_CPU_MAPS; Arnd wants to be reminded, but only once :)
5) Revert most of S390 smp_call_function_mask->smp_call_function_many: it's
safer to just do the minimal conversion.
6) Remove __deprecated from smp_call_function_mask: we're not pushing
replacement patches yet so it's not appropriate, and it breaks sparc64
which compiles arch/sparc with -Werror.
7) Hack header to set CONFIG_NR_CPUS for UP on archs; safer than touching
Kconfigs for them. Also update comment.
Thanks,
Rusty.

guys. I already spent hours integrating the "latest" of this stuff today
and established baseline quality for it on x86. I've dropped 4a792c2 and
pushed out a new tip/cpus4096-v2, please send append-only patches for
the rest of the changes.

Ok, no problem. I was integrating in the changes you already made so they
would not be dropped. But I'll send "update" patches instead of "replacement"
patches if you prefer.

how big are the deltas? You might send a single interdiff - it's
supposed to be all small, right?

It's pretty trivial, mostly removing things. The big problem is Rusty
based his on Linus' tree (and he's offline now), so I need to apply his
patches to that tree and then generate "diff" patches for your tree.
Btw, I'm still having trouble building a "baseline" config using the
cpus4096-v2 branch that actually boots. (UP boots ok.) Is this the
correct .git/config:
[core]
repositoryformatversion = 0
filemode = true
bare = false
logallrefupdates = true
[remote "linus"]
url = git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
fetch = +refs/heads/*:refs/remotes/linus/*
[remote "tip"]
url = git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
fetch = +refs/heads/*:refs/remotes/tip/*
[branch "tip-latest"]
remote = tip
merge = refs/heads/master
[branch "cpus4096-v2"]
remote = tip
merge = refs/heads/cpus4096-v2
It won't let me do a:
mkdir linux-2.6.tip
cd linux-2.6.tip
git-init-db
git-remote add linus git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git
git-remote add tip git://git.kernel.org/pub/scm/linux/kernel/git/tip/linux-2.6-tip.git
git-remote update
git-checkout -b cpus4096-v2 tip/cpus4096-v2
git checkout: updating paths is incompatible with switching branches/forcing
Did you intend to checkout 'tip/cpus4906-v2' which can not be resolved as commit?
or:
git-checkout tip/cpus4906-v2
error: pathspec 'tip/cpus4906-v2' did not match any file(s) known to git.
Did you forget to 'git add'?
Thanks,
Mike

Sorry, that was a cut and paste error in this example. I've tried both these
.git/config's and both hang during bootup:

Here are the only changes I could find from Rusty's last patches that
apply to tip/cpus4096-v2.
* Fix NR_CPUS reference in arch/powerpc/platforms/cell/spu_base.c
* modify arch/x86/Kconfig so CONFIG_NR_CPUS is always defined. Also it
does not prompt if MAXSMP is set.
* change include/linux/threads.h so CONFIG_NR_CPUS is defined for those
arch's that do not define it.

Note I haven't been able test anything on this branch, patches or not.
(Everything that has SMP set hangs during startup. I've tried a number
of approaches to creating a source tree but all fail.)

Curious thing happens here. I created the tree as you suggested (branch tip/cpus4096-v2)
and copied in your .config file. Running it through "silentoldconfig" (choosing only
the defaults), I get the following changes. This makes me suspect that I'm not testing
the same thing as you are...? Perhaps my git setup was not correct?

no - i have some extras that forces on SMP for example to make it more
likely to trigger in random tests (it's far more interesting from a QA
point of view than UP).
so as long as you select SMP you should get the same config. Lemme do a
.config you can plug in.

i've attached the config that will build and boot with the
tip/cpus4096-v2 branch.
(I'm now double-checking whether it reproduces those slab corruption
messages.)

Just drop it. It's a conversion, so it doesn't really belong in this "new
API" stuff. Nothing depends on it, and we need to be sure it's that which is
causing the blowup.
Oh, and here's (one) problem:
*nodemask = node_to_cpumask(cpu_to_node(i));
This is an old-style cpumask_t assigment, but nodemask wasn't allocated
NR_CPUS bits if CONFIG_CPUMASK_OFFSTACK. This is why assignment is banned
(and will eventually fail compile), but that conversion hasn't been done on
sched.c yet, so this patch is ahead of its time.
Thanks,
Rusty.

Note that "removed" and "deprecated" are using the terms loosely. No old API
was removed, and I didn't actually mark anything __deprecated (I just
documented it in the header).

i've propagated these impact-line fixes into tip/cpus4096-v2, thanks
Rusty!
And once we have something that works reasonably well we can do a
final respin of this branch with all fixlets back-propagated, for good
bisectability.
the current variant, which force-disabled MAXSMP (i.e. only uses the
non-dynamic cpumask_t branch), is looking good in my testing so far.
(it has passed more than 100 boot tests today, on a handful of x86
boxes)
