[PATCHSET x86/core/percpu] improve the first percpu chunk allocation

[Tejun Heo]

Hello, all.

This patchset improves the first percpu chunk allocation.  The problem
is that the dynamic percpu area allocation maps the whole percpu area
into vmalloc area using 4k mappings which adds considerable amount of
TLB pressure.

This patchset modularizes the first percpu chunk allocation and uses
different allocation schemes to optimize TLB usage.

* On !NUMA, the first chunk is allocated directly using
  alloc_bootmem() thus adding no TLB pressure whatsoever.

* On NUMA, the first chunk is remapped using large pages and whatever
  is left in the large page is given back to the bootmem allocator.
  This makes each cpu use an additional large TLB entry for the first
  chunk but still is much better than using many 4k TLB entries.

This patchset contains the following ten patches.

  0001-percpu-fix-pcpu_chunk_struct_size.patch
  0002-bootmem-clean-up-arch-specific-bootmem-wrapping.patch
  0003-bootmem-reorder-interface-functions-and-add-a-missi.patch
  0004-vmalloc-add-align-to-vm_area_register_early.patch
  0005-x86-update-populate_extra_pte-and-add-populate_ex.patch
  0006-percpu-remove-unit_size-power-of-2-restriction.patch
  0007-percpu-give-more-latitude-to-arch-specific-first-ch.patch
  0008-x86-separate-out-setup_pcpu_4k-from-setup_per_cpu.patch
  0009-x86-add-embedding-percpu-first-chunk-allocator.patch
  0010-x86-add-remapping-percpu-first-chunk-allocator.patch

0001 fixes a bug introduced by earlier patch.  0002-0006 prepares for
better first chunk allocation.  0007 updates make percpu allocator
initialization more flexible.  0008-0010 modularizes and adds better
allocation schemes for x86.

[PATCH 01/10] percpu: fix pcpu_chunk_struct_size

[Tejun Heo]

Impact: fix short allocation leading to memory corruption

While dropping rvalue wrapping macros around global parameters,
pcpu_chunk_struct_size was set incorrectly resulting in shorter page
pointer array.  Fix it.

[PATCH 02/10] bootmem: clean up arch-specific bootmem wrapping

[Tejun Heo]

Impact: cleaner and consistent bootmem wrapping

By setting CONFIG_HAVE_ARCH_BOOTMEM_NODE, archs can define
arch-specific wrappers for bootmem allocation.  However, this is done
a bit strangely in that only the high level convenience macros can be
changed while lower level, but still exported, interface functions
can't be wrapped.  This not only is messy but also leads to strange
situation where alloc_bootmem() does what the arch wants it to do but
the equivalent __alloc_bootmem() call doesn't although they should be
able to be used interchangeably.

This patch updates bootmem such that archs can override / wrap the
backend function - alloc_bootmem_core() instead of the highlevel
interface functions to allow simpler and consistent wrapping.  Also,
HAVE_ARCH_BOOTMEM_NODE is renamed to HAVE_ARCH_BOOTMEM.

This won't suffice as reserve_bootmem() doesn't use
alloc_bootmem_core(), so now you effectively removed the node-0
restriction for reserve_bootmem() on this configuration.

I wonder why this setup wants to register several bootmem nodes but
only use node 0, anyway.  Does someone remember? :)

Yeah, that's why it's a macro.  I thought about putting it into a
separate header file, say, asm/bootmem-wrapper.h and including it only
from bootmem.c but it looked like an overkill, so...

Thanks.

[PATCH 03/10] bootmem: reorder interface functions and add a missing one

[Tejun Heo]

Impact: cleanup and addition of missing interface wrapper

The interface functions in bootmem.h was ordered in not so orderly
manner.  Reorder them such that

* functions allocating the same area group together -
  ie. alloc_bootmem group and alloc_bootmem_low group.

* functions w/o node parameter come before the ones w/ node parameter.

* nopanic variants are immediately below their panicky counterparts.

While at it, add alloc_bootmem_pages_node_nopanic() which was missing.

[PATCH 04/10] vmalloc: add @align to vm_area_register_early()

[Tejun Heo]

Impact: allow larger alignment for early vmalloc area allocation

Some early vmalloc users might want larger alignment, for example, for
custom large page mapping.  Add @align to vm_area_register_early().
While at it, drop docbook comment on non-existent @size.

[PATCH 05/10] x86: update populate_extra_pte() and add populate_extra_pmd()

[Tejun Heo]

Impact: minor change to populate_extra_pte() and addition of pmd flavor

Update populate_extra_pte() to return pointer to the pte_t for the
specified address and add populate_extra_pmd() which only populates
till the pmd and returns pointer to the pmd entry for the address.

For 64bit, pud/pmd/pte fill functions are separated out from
set_pte_vaddr[_pud]() and used for set_pte_vaddr[_pud]() and
populate_extra_{pte|pmd}().

[PATCH 06/10] percpu: remove unit_size power-of-2 restriction

[Tejun Heo]

Impact: allow unit_size to be arbitrary multiple of PAGE_SIZE

In dynamic percpu allocator, there is no reason the unit size should
be power of two.  Remove the restriction.

As non-power-of-two unit size means that empty chunks fall into the
same slot index as lightly occupied chunks which is bad for reclaming.
Reserve an extra slot for empty chunks.

[PATCH 07/10] percpu: give more latitude to arch specific first chunk initialization

[Tejun Heo]

Impact: more latitude for first percpu chunk allocation

The first percpu chunk serves the kernel static percpu area and may or
may not contain extra room for further dynamic allocation.
Initialization of the first chunk needs to be done before normal
memory allocation service is up, so it has its own init path -
pcpu_setup_static().

It seems archs need more latitude while initializing the first chunk
for example to take advantage of large page mapping.  This patch makes
the following changes to allow this.

* Define PERCPU_DYNAMIC_RESERVE to give arch hint about how much space
  to reserve in the first chunk for further dynamic allocation.

* Rename pcpu_setup_static() to pcpu_setup_first_chunk().

* Make pcpu_setup_first_chunk() much more flexible by fetching page
  pointer by callback and adding optional @unit_size, @free_size and
  @base_addr arguments which allow archs to selectively part of chunk
  initialization to their likings.

[PATCH 08/10] x86: separate out setup_pcpu_4k() from setup_per_cpu_areas()

[Tejun Heo]

Impact: modularize percpu first chunk allocation

x86 is gonna have a few different strategies for the first chunk
allocation.  Modularize it by separating out the current allocation
mechanism into pcpu_alloc_bootmem() and setup_pcpu_4k().

[PATCH 09/10] x86: add embedding percpu first chunk allocator

[Tejun Heo]

Impact: add better first percpu allocation for !NUMA

On !NUMA, we can simply allocate contiguous memory and use it for the
first chunk without mapping it into vmalloc area.  As the memory area
is covered by the large page physical memory mapping, it allows the
dynamic perpcu allocator to not add any TLB overhead for the static
percpu area and whatever falls into the first chunk and the
implementation is very simple too.

[PATCH 10/10] x86: add remapping percpu first chunk allocator

[Tejun Heo]

Impact: add better first percpu allocation for NUMA

On NUMA, embedding allocator can't be used as different units can't be
made to fall in the correct NUMA nodes.  To use large page mapping,
each unit needs to be remapped.  However, percpu areas are usually
much smaller than large page size and unused space hurts a lot as the
number of cpus grow.  This allocator remaps large pages for each chunk
but gives back unused part to the bootmem allocator making the large
pages mapped twice.

This adds slightly to the TLB pressure but is much better than using
4k mappings while still being NUMA-friendly.

Ingo suggested that this would be the correct approach for NUMA.

Hm, i think there still must be some basic misunderstanding 
somewhere here. Let me describe the design i described in the 
previous mail in more detail.

In one of your changelogs you state:

|    On NUMA, embedding allocator can't be used as different 
|    units can't be made to fall in the correct NUMA nodes.

This is a direct consequence of the unit/chunk abstraction, and 
i think that abstraction is wrong.

What i'm suggesting is to have a simple continuous [non-chunked, 
with a hole in the last bits of the first 2MB] virtual memory 
range for each CPU.

This special virtual memory starts with a 2MB page (for the 
static bits - perhaps also with a default starter dynamic area 
appended to that - we can size this reasonably) and continues 
with 4K mappings at the next 2MB boundary and goes on linearly 
from that point on.

The variables within this singular 'percpu area' mirror each 
other amongst CPUs. So if a dynamic (or static) percpu variable 
is at offset 156100 in CPU#5's range - then it will be at offset 
156100 in CPU#11's percpu area too. Each of these areas are 
tightly packed with that CPU's allocations (and only that CPU's 
allocations), there's no chunking, no units.

As with your proposal this tears down the current artificial 
distinction between static and dynamic percpu variables.

But with this approach we'd the following additional advantages:

- No dynamic-alloc single-allocation size limits _at all_ in 
  practice. [up to the total size of the virtual memory window]

  ( With your current proposal the dynamic alloc is limited to
    unit size - which is looks a bit inflexible as unit size
    impacts other characteristics so when we want to increase 
    the dynamic allocation size we'd also affect other areas of 
    the code. )

  percpu_alloc() would become as limitless (on 64-bit) as 
  vmalloc().

- no NUMA complications and no NUMA assymetry at all. When we 
  extend a CPU's percpu area we do NUMA-local allocations to 
  that CPU. The memory allocated is purely for that CPU's 
  purpose.

- We'd have a very 'compressed' pte presence in the pagetables: 
  the dynamic percpu area is as tightly packed as possible. With 
  a chunked design we 'scatter' the ptes a bit more broadly.

The only thing that gets a bit trickier is sizing - but not by 
much. The best way we can size this without practical 
complications on very small or very large systems would by 
setting the maximum _combined_ size for all percpu allocations.

Say we set this 'PERCPU_TOTAL' limit to 4 GB. That means that if 
there are 8 possible CPUs, each CPU can have up to 512 MB of 
RAM. That's plenty in practice.

We can do this splitup dynamically during bootup, because the 
area is still fully linear, relative to the percpu offset.

[ A system with 4k CPUs would want to have a larger PERCPU_TOTAL 
  - but obviously it cannot be really mind-blowingly large 
  because the total max has to be backed up with real RAM. So 
  realistically we wont have more than 1TB in the next 10 years 
  or so. Which is still well below the limitations of the 64-bit 
  address space. ]

In a non-chunked allocator the whole bitmap management becomes 
much simpler and more straightforward as well. It's also much 
easier to think about than an interleaved unit+chunk design.

The only special complication is the setup of the initial 2MB 
area - but that is tricky to bootstrap anyway because we need to 
set it up before the page allocator gets initialized. It's also 
worthwile to put the most common percpu variables, and an 
expected amount of dynamic area into a 2MB TLB.

Hm?

Not at all.  That's an optimization for !NUMA.  The remap allocator is
what can be done on NUMA.  Chunking or not doesn't make any difference
in this regard.  The only difference between chunking and not chunking
is whether separately allocated percpu offsets have more or less holes
inbetween them, which is irrelevant for all purposes.

> and i think that abstraction is wrong.

No, it's not wrong.  It simply is irrelevant - it's congruent
vs. contiguos and all that we need is congruent.  Contiguous of course
achieves congruent but it doesn't make any difference for this
purpose.

Please take a look at the remap allocator.  That's what you had in
mind for the contiguos mapping.  The embedding allocator is an
improvement specifically for !NUMA so that it doesn't even have to
spend the single extra TLB entry for the first 2MB page, which BTW
would be impossible with contiguous mapping.

Yes, I did understand that and did reply that in my previous email.

=== QUOTE ===
The new percpu_alloc() already does that.  Chunking or not makes no
difference on this regard.  The only difference whether there are more
holes in the allocated percpu addresses or not, which basically is
irrelevant and chunking makes things much more flexible and scalable.
ie. It can scale toward many many cpus or large large percpu areas
wheras making the areas contiguous make the scalability determined by
the product of the two.

Also, contiguous per-cpu areas might look simpler but it actually is
more complicated because it becomes much more arch dependent.  With
chunking, the complexity is in generic code as virtual address and
stuff are already in place.  If the cpu areas need to be made
contiguous, the generic code will get simpler but each arch needs to
come up with new address space layout.

There simply isn't any measurable advantage to making the area
contiguous.

There is no artificial limit on unit_size.  Contiguous is special form
of congruent and thus it simply can't be more flexible than congruent.
If the maximum allocation size is somthing to worry about just bumping
the MIN constant should do the trick at the cost of consuming more
virtual address, but seriously I don't think the maximum allocation
size is something we need to worry about.  64k is way more than
enough.

Chunking or not doesn't make any difference in this regard.  The
posted allocator does exactly what you described above.

Can you please elaborate a bit?

If you're worried about packing, with the current usage pattern, it
doesn't matter at all.  There are lots of small allocations and larger
ones often need small alignment.  They pack alright.

I think it's a pretty big problem on 32bit and also it makes
implementing dynamic allocator much more involved for each arch wheras
chunking puts the complexity at the generic code and just uses the
existing vmalloc address mapping.  I really can't see advantage of
contiguous allocation.

With chunking, we simply don't have to think about any of this.

I don't know.  The bitmap allocator itself would be the same.  It's
just that with chunking we have multiple of them and complexities are
added when choosing where to allocate and reverse mapping pointer to
its chunk.  I think it's reasonably straight forward as it is.

Plus, it's not like we'll be able to do things as simple as
module_percpu allocator does anyway.  If we map/unmap pages using
highest allocated mark, single allocation can hold up vast amount of
memory.  If we start depopulating in the middle, we no longer can use
simple bitmap allocator and try to group allocations so that we don't
waste a lot of pages.  Reclamation is one of the reasons why I chose
chunking.

Yeah, it's bootstrapping.  No matter what we do, it's gonna be a
little bit hairy.

It's not an optimization, it's a pessimisation :)

Please read what i wrote to you. We want the percpu static and 
dynamic areas to be _one and the same thing_. (With just the 
different that static allocations have a handy compile-time 
offset shortcut - but the access is still the same.)

Right now, with your latest code we still have this:

   * Use this to get to a cpu's version of the per-cpu object
   * dynamically allocated. Non-atomic access to the current  CPU's
   * version should probably be combined with get_cpu()/put_cpu().
   */
  #define per_cpu_ptr(ptr, cpu)   SHIFT_PERCPU_PTR((ptr), per_cpu_offset((cpu)))

This slows down per_cpu_ptr() and makes the dynamic percpu case 
a second-class citizen because most actual usages are for the 
current CPU, still have to go via the per_cpu_offset() 
indirection.

I.e. we have things like:

        const int cpu = get_cpu();

        u8 *scratch = *per_cpu_ptr(ipcomp_scratches, cpu);

Instead of a straight:

        u8 *scratch = *this_cpu_ptr(ipcomp_scratches);

We cannot do that optimization due to the NUMA and SMP 
assymetry. If NUMA and SMP had the same linear structure, as i 
suggested we do, we could do it.

Currently you rely on per_cpu_offset() indirection basically as 
a soft-TLB entry covering all dynamic allocations. That sucks.

Ok?

Heh... I suppose this is why you and I are keeping disagreeing.
Currently, __my_cpu_offset is defined as percpu_read(this_cpu_off) and
__get_cpu_var() is defined as (*SHIFT_PERCPU_PTR(&per_cpu_var(var),
__my_cpu_offset), so our static access is now basically *per_cpu_ptr().

If per_cpu_ptr() is second class citizen, get_cpu_var() is too.  :-)
So, there's nothing more indirect about per_cpu_ptr() compared to
get_cpu_var() anymore.

No no no, there's no difference whatsoever.  Either I'm glossly
misunderstanding something or you're because I really cannot see any
difference between static and dynamic ones except for whether the
offset itself is static or not.

What's missing is unification of static and dynamic accessors and thus
the faster accessors - percpu_read() and friends - for dynamic ones.
This will be the next round of patches.

>

IIUC, the per_cpu_offset() indirection stems from %gs addressing
restriction.  We can't teach gcc about it and so the percpu_read() and
friends.  Come on, our static percpu variable uses per_cpu_offset()
too.

If my reality seems to be disassociated from other's more than it
usually is, please feel free to enlighten me.  :-)

Thanks.

Ok, good - we are in agreement then and i'll wait for those

+               return -EINVAL;

This is what makes no sense (why force the static percpu area 
into 4K mappings on NUMA).

You do it because i think you misunderstood my original 2MB TLB 
static area suggestion. setup_pcpu_embed() does this now:

+       pcpue_ptr = pcpu_alloc_bootmem(0, num_possible_cpus() * pcpue_unit_size,
+                                      PAGE_SIZE);

That is not NUMA-friendly indeed.

What should be done instead is to up the unit size to 2MB as i 
suggested, and to allocate 2MB sized and 2MB aligned 
numa-correct area for each CPU, via bootmem.

To quote my original mail:

I.e. each individual 2MB allocated largepage can then be 
remapped as a 2MB TLB to the high (vmalloc) area. Followed by 
ordinary 4K mappings for regular percpu_alloc() pages.

( and the partial, unused pages within this initial chunk are 
  returned to bootmem. )

That will be NUMA-friendly and i suspect we should also use it 
on SMP just to get that aspect of the code tested better.

Do _not_ allocate the units together in one bootmem allocation 
because that's not NUMA-friendly.

Ok?

No, the first allocator tried is remap allocator which will do the 2MB
remapping thing if NUMA.  If not, it gives its way to embedding
allocator which only kicks in for pse && !numa.  The 4k thing is just
the last resort.  We might as well kill it and make it

 if (numa)
	do remap
 else
	do embed
 panic if failed

The 4k thing is the final fallback for cases where pse isn't
supported.

NUMA uses 2MB remapping.  Non-NUMA uses embedding.  If you're annoyed
about the embedding allocator, we can drop it but given that most of
the machines in the wild are non-NUMA and the code to do the trick is
quite simple, I think it justifies its existence.

YES, the posted code does EXACTLY that for NUMA!!!!

I did understand that the first time around.

For testing coverage, we can make a debug parameter or something but
think about it.  The embedding allocator is ~100 lines of well
commented code which is dropped once init is complete and it always
saves a 2MB TLB entry for all the non-NUMA machines out there.  It is
a very low cost optimization for >90% of machines out there.

Again, it doesn't do that for NUMA.

Note that everyone keeps talking about "a" TLB entry; I wanted to make
sure (esp. for those of us reading from the sidelines), it's not: it's
up to num_possible_cpus() TLB entries.  Of course, many paths won't access

Hmm, fairly rare, but not incredibly:

percpu: measure use

With the idea of using virtual mappings for percpu regions, we wonder
how often we access other CPU's per-cpu variables.

Actually it's up to the number of actual CPUs in the system... obviously 
there isn't any data allocated for non-present CPUs.

well, we allocate percpu data for each possible CPU.

In the overwhelming majority of cases that means all actual 
CPUs.

Sure. We want to compress data usage on every level of caching. 

Part of that is to compress the ptes themselves, as they are 
laid out in the pagetables. With your current small-chunks setup 
we get this address space layout:

    u1 .... [hole] ... u2 .. [hole] .... u3 ... [hole]

Where the 'hole' is the units belonging to other CPUs - but this 
CPU is largely uninterested in it. These 'holes' are the larger 
the more CPUs there are in the system.

A 'hole' there means that we have a number of ptes that are 
unused in that CPU. That is bad in several ways:

 - those ptes will still be cached in the CPU - just not used 
   for anything by that CPU. So the cache utilization ratio for 
   those ptes will be very low.

 - a modern x86 CPU's TLB walker will prefetch into nearby 
   present ptes quite agressively, based on access patterns it 
   detects. Having a lot of 'other CPU' ptes present will fool 
   this CPU into prefetching them, if there's nearby usage. 
   Those TLB entries are lost and they can create pressure on 
   and eliminate useful TLB entries as well.

 - as the number of CPUs increases in the system, the worse this 
   situation gets. So up until a certain limit (when the hole
   becomes so large that the CPU does not speculate to any 
   additional level into it) this effects gets worse gradually.

So what i'm saying is that these are strong reasons for us to 
want to make the unit size to be something like 2MB - on 64-bit 
x86 at least.

( Using a 2MB unit size will also have another advantage: _iff_ 
  we can still allocate a hugepage at that point we can map it 
  straight there when extending the dynamic area. )

Thanks for the explanation.  Yeap, it would be nice to have units
aligned on 2MB boundary.  We'll need to add @align to vm area alloc
function to do it correctly.  As for using large page, it would be
nice if we can do that automatically.  Upfront 2MB unit allocation is
probably too expensive but merging 4k pages into a large page (if we
can get them) will add a lot of irregular latency too.  Hmmm...

Yeah, largepage support - if we ever get there (the chances of 
finding a proper 2MB aligned 2MB sized chunk of physical memory 
are not very good except the first few minutes of uptime), 
should indeed be automatic to all get_vm_area() users - 
vmalloc(), ioremap() and now percpu.c.

I think a far more realistic angle to utilize more of the 2MB 
TLB will be to gradually increase PERCPU_ENOUGH_ROOM, as we 
observe more and more percpu_alloc() sites in the kernel. Right 
now it's pretty rare so going beyond the 8K we do for modules 
would probably be a waste of RAM.

The problem is that it doesn't always know what the callers want.
It would be trivial (there is already support in the virtual
address allocator) to specify alignment. Then kernel page table
setup could presumably use larger size mappings if it is given
contiguous memory.

It might possibly be useful for smaller NUMA machines using
hashdist for the big early hashes (hash sizes scale log, but
number of nodes tends to scale linearly with memory size, so
2MB per node for hashes would probably be far too much on big
machines).

Well, as long as we can go up in unit size to 2MB (on 64-bit 
x86) i'm fine with that model.

There's no granularity artifacts, right? pcpu_populate_chunk() 
intelligently only populates pages on an as-needed basis, so 
extending the percpu areas with a 2MB unit does not trigger 
nr_cpus*2MB allocations straight away.

The code looks very clean and if we can agree on the SMP/NUMA 
symmetry and the dynamic-ptr optimizations that it allows, plus 
if you can up the unit size to 2MB on 64-bit x86, i'm a happy 
camper and will pull it.

Yeap, it doesn't although reclamation is done per-chunk currently.

Notice the strange blank PGTABLE entry.

The reason is init_pg_table is big enough, and zero range is called
with init_memory_mapping/reserve_early().

So try to check the range in reserve_early()

ok, but these seem to be genuinely yours.

one build failure:

 arch/x86/kernel/setup_percpu.c: In function ‘setup_per_cpu_areas’:
 arch/x86/kernel/setup_percpu.c:442: error: ‘ptr’ undeclared (first use in this function)
 arch/x86/kernel/setup_percpu.c:442: error: (Each undeclared identifier is reported only once
 arch/x86/kernel/setup_percpu.c:442: error: for each function it appears in.)

one new warning:

 mm/percpu.c: In function ‘pcpu_map’:
 mm/percpu.c:604: warning: unused variable ‘last’

and one tip:master merge impact due to API change:

 kernel/trace/trace_functions_graph.c: In function ‘graph_trace_close’:
 kernel/trace/trace_functions_graph.c:836: error: implicit declaration of function ‘percpu_free’

that's free_percpu() now, right?

Btw., why was this rename done? We generally standardize on 
hierarchical names, going from the more general to the more 
specific names, left to right. So we have 
<subsystem>_<functionality>_<subtype> sort of names generally.

[PATCH x86/core/percpu 1/2] x86, percpu: fix minor bugs in setup_percpu.c

[Tejun Heo]

Recent changes in setup_percpu.c made a now meaningless DBG()
statement fail to compile and introduced a
comparison-of-different-types warning.  Fix them.

Compile failure is reported by Ingo Molnar.

[PATCH x86/core/percpu 2/2] x86: convert cacheflush macros inline functions

[Tejun Heo]

Impact: cleanup

Unused macro parameters cause spurious unused variable warnings.
Convert all cacheflush macros to inline functions to avoid the
warnings and achieve better type checking.

Re: [PATCHSET x86/core/percpu] improve the first percpu chunk allocation

Hello, Ingo.

Patches posted to fix the build failure and warning.  Patches are also
available in the usual git tree.

It's a strange story and not really a rename.

We had __percpu_alloc_mask(), percpu_alloc(), __alloc_percpu() and
alloc_percpu() and of course matching frees.  The percpu_*() stuff was
introduced so that allocations can take online cpus into
consideration.  So, percpu_alloc() uses cpu_online_map as the default
allocation mask while alloc_percpu() uses cpu_possible_map.  The
allocation mask thing never really took off and there virtually was no
user and got killed.

If the only merge impact was percpu_free() and it's not missing
percpu_alloc(), it could be that allocation path used alloc_percpu()
but free path used percpu_free().

Thanks.

Hmm... kernel.org is slow today.  It hasn't been mirrored yet.  The
commit ID is d325100504f1d0c296a1fbfef558deaa655e2240.  If it doesn't

[PATCH core/percpu] percpu: fix too low alignment restriction on UP

[Tejun Heo]

UP __alloc_percpu() triggered WARN_ON_ONCE() if the requested
alignment is larger than that of unsigned long long, which is too
small for all the cacheline aligned allocations.  Bump it up to
SMP_CACHE_BYTES which kmalloc allocations generally guarantee.

Hello, Ingo.

I somehow completely forgot about testing UP.  Sorry about that. :-)
The following patch should do it.  Also available in the #tj-percpu
tree.

Thanks.

Agreed, but we had both, doing identical things, and free_percpu outnumbered
percpu_free by a significant factor (about 40 to 5 IIRC).

Simple pragmatism, and it matches alloc_percpu.

40 places to rename => peanuts! :-)

it also matches other allocator mis-namings in mm/*.c.
I concur.
