Hi Ralf,

Following is some janitorial stuff again. Please consider.

Thanks,

[PATCH 1/3] [MIPS] make the pcibios_max_latency variable static

[Dmitri Vorobiev]

The pcibios_max_latency variable is needlessly defined global,
and this patch makes it static.

Build-tested using malta_defconfig.

[PATCH 2/3] [MIPS] fix missing prototypes in asm/fpu.h

[Dmitri Vorobiev]

While building the Malta defconfig, sparse spat the following
warnings:

>>>>>>>>>>>>>>>>>>
arch/mips/math-emu/kernel_linkage.c:31:6: warning: symbol
'fpu_emulator_init_fpu' was not declared. Should it be static?

arch/mips/math-emu/kernel_linkage.c:54:5: warning: symbol
'fpu_emulator_save_context' was not declared. Should it be
static?

arch/mips/math-emu/kernel_linkage.c:68:5: warning: symbol
'fpu_emulator_restore_context' was not declared. Should it be
static?
>>>>>>>>>>>>>>>>>>

This patch fixes these errors by adding the proper prototypes
to the include/asm-mips/fpu.h header, and actually using this
header in the sparse-spotted source file.

Build-tested with Malta defconfig.

[PATCH 3/3] [MIPS] add missing prototypes to asm/page.h

[Dmitri Vorobiev]

This patch fixes the following sparse warnings:

>>>>>>>>>>>>>>>>>>
arch/mips/mm/page.c:284:16: warning: symbol
'build_clear_page' was not declared. Should it be static?

arch/mips/mm/page.c:426:16: warning: symbol 'build_copy_page'
was not declared. Should it be static?
>>>>>>>>>>>>>>>>>>

The fix is to add appropriate prototypes to the header
include/asm-mips/page.h.

Build-tested against Malta defconfig.

[PATCH 1/3 part 2] [MIPS] make the pcibios_max_latency variable static

[Dmitri Vorobiev]

Along with making the pcibios_max_latency variable static,
its declaration needs to be removed from the header file.

Hi Ralf,

Forgot about this one yesterday, sorry.

No big deal, lmo's internet connection was down for part of the afternoon
so I wasn't doing as much patch stuff as I was hoping to ...

I folded part 2 into part 1 of your patch and applied the result.

Thanks,

  Ralf

I'm not terribly fond of exporting these private prototypes by making
their prototypes widely available.  I see it's need to make sparse a more
productive tool, so I applied the patch though.

Same comment as for 2/3 applies.  Patch applied.  Thanks,
