At least on ia64 vmalloc_end is a global variable that VMALLOC_END
expands to. Hence having a local variable named vmalloc_end and
initialized from VMALLOC_END won't work on such platforms. Rename
these variables, and for consistency also rename vmalloc_start.

erk.  So does 2.6.32's vmalloc() actually work correctly on ia64?

Perhaps vmalloc_end wasn't a well chosen name for an arch-specific
global variable.

arch/m68k/include/asm/pgtable_mm.h does the same thing.  Did it break too?

Hmmm... ISTR writing a patch updating ia64 so that it doesn't use that
macro.  Looking it up....  Yeap, 126b3fcdecd350cad9700908d0ad845084e26a31
in percpu#for-next.

    ia64: don't alias VMALLOC_END to vmalloc_end
    
    If CONFIG_VIRTUAL_MEM_MAP is enabled, ia64 defines macro VMALLOC_END
    as unsigned long variable vmalloc_end which is adjusted to prepare
    room for vmemmap.  This becomes probnlematic if a local variables
    vmalloc_end is defined in some function (not very unlikely) and
    VMALLOC_END is used in the function - the function thinks its
    referencing the global VMALLOC_END value but would be referencing its
    own local vmalloc_end variable.
    
    There's no reason VMALLOC_END should be a macro.  Just define it as an
    unsigned long variable if CONFIG_VIRTUAL_MEM_MAP is set to avoid nasty
    surprises.

2.6.32 doesn't use new allocator on ia64 yet and the above commit will
be sent to Linus soon which will also enable new allocator.

Thanks.

Hello,

Oh... m64k does the same thing.  I think the correct thing to do here
would be to convert arch code as in ia64.  I think defining
VMALLOC_END to vmalloc_end is a bit error-prone.  If it were defined
simply as vmalloc_end, it's unnoticeable by both the compiler and
developer.

Thanks.

On SUN3, m68k defines macro VMALLOC_END as unsigned long variable
vmalloc_end which is adjusted from mmu_emu_init().  This becomes
problematic if a local variables vmalloc_end is defined in some
function (not very unlikely) and VMALLOC_END is used in the function -
the function thinks its referencing the global VMALLOC_END value but
would be referencing its own local vmalloc_end variable.

There's no reason VMALLOC_END should be a macro.  Just define it as an
unsigned long variable to avoid nasty surprises.

Okay, here it is.  Compile tested.  Geert, Roman, if you guys don't
object, I'd like to push it with the rest of percpu changes to Linus.
What do you think?

Thanks.

That would be good.  How much mess would it make?

According to Tejun the problem is just cosmetic (i.e. causes build
warnings), since the functions affected aren't being used (yet) on
ia64. So feel free to drop the patch again, given that he has a patch
queued to address the issue by renaming the arch variable.

I wonder though why that code is being built on ia64 at all if it's not
being used (i.e. why it doesn't depend on a CONFIG_*, HAVE_*, or
NEED_* manifest constant).

Hmm... it shouldn't be building.  Can you please attach .config?

Thanks.

How can it not be building? It's in vmalloc.c (which must be built) and not
inside any conditional.

>Can you please attach .config?

Attached anyway.

Ah... yes, right.  Somehow I was thinking it lived in percpu.c.  Sorry
about that.  Probably the right thing to do is to wrap the function
inside CONFIG ifdef's.  I'll prep a patch.

Thanks.

pcpu_get_vm_areas() is used only when dynamic percpu allocator is used
by the architecture.  In 2.6.32, ia64 doesn't use dynamic percpu
allocator and has a macro which makes pcpu_get_vm_areas() buggy via
local/global variable aliasing and triggers compile warning.

The problem is fixed in upstream and ia64 uses dynamic percpu
allocators, so the only left issue is inclusion of unnecessary code
and compile warning on ia64 on 2.6.32.

Don't build pcpu_get_vm_areas() if legacy percpu allocator is in use.

So this is only needed for the .32 kernel stable tree?  Not .31?  And
it's not upstream as it was solved differently there?

Yeap, .32 is the only affected one and in the upstream the problem is
solved way back and ia64 is already using the new dynamic allocator.

Thanks.

Great, I've queued this up now, thanks for letting me know.

I thought the new code must be used in order for the new percpu allocator
to work? Or is this referring to other code?

If all the pieces are in (either Linus tree, or linux-next) then
it is working (well these both still build & boot on my test systems).

Christoph,  I have access to a 640p system for a couple more weeks if
there's anything you'd like me to check out.

Boot with 2.6.32 and see if the per cpu allocator works. Check if there
are any changes to memory consumption. Create a few thousand virtual
ethernet devices and see if the system keels over.

It may also be good to run some scheduler test. Compare AIM9 of latest
SLES with 2.6.32. Concurrent page fault test? Then a performance test with
lots of concurrency but the usual stuff wont work since HPC apps usually
pin.

Run latencytest (available in the lldiag package) from
kernel.org/pub/linux/kernel/people/christoph/lldiag and see how the
disturbances by the OS are changed.

Argh. You have to wait till 2.6.33-rc1 I believe to get the conversion of
the SNMP MIBs for the new per cpu allocator.

Any advice on how to go about the above would be helpful... ;-)

I'm doing some aim7/9 comparisons right now between SPARSE and DISCONTIG
memory configs using sles11 + 2.6.32.  Which other benchmarks would you
recommend for the other tests?

I'll put that on the list.

I believe you can create an additional alias device with

ifconfig eth0:<N>

or so.

Rename to m68k_vmalloc_{end,start}?

Hmm, sounds better than introducing allcaps variables...

Hello,

We definitely can do that too but I don't know.  It still has the risk
of aliasing behind both the developer's and compiler's back.  Aliasing
a macro directly to a macro just isn't a very good idea.  We can
definitely make it more complex - make the prefix more unlikely,
prevent it from being used as lvalue and so on but given that it's a
pretty special case anyway, I think all caps variable isn't too bad
here.

But you're the maintainer, if you prefer the following version, I'll
go forward with it.

Thanks.

* [PATCH] m68k: rename global variable vmalloc_end to m68k_vmalloc_end

On SUN3, m68k defines macro VMALLOC_END as unsigned long variable
vmalloc_end which is adjusted from mmu_emu_init().  This becomes
problematic if a local variables vmalloc_end is defined in some
function (not very unlikely) and VMALLOC_END is used in the function -
the function thinks its referencing the global VMALLOC_END value but
would be referencing its own local vmalloc_end variable.

Rename the global variable to m68k_vmlloc_end which is much less
likely to be used as local variable name.
