      [POWERPC] Fix powerpc vmlinux.lds.S · 832a791c
      由 Benjamin Herrenschmidt 提交于 
      Sam's recent change in 7664709b
broke things for us because we ended up with *(.text.*) before
*(.text), whereas previously *(.text) was first.  This was
important because the start of the text section contains the
kernel entry point.

In fact, we don't need that *(.text.*) thing anymore and it
incorrectly matched .text.init.refok, thus putting it before
.text. .. ouch !

      [POWERPC] Fix typo: MMCR0_PMA0 != MMCR0_PMAO · 177e9ea4
      由 Anton Blanchard 提交于 
      pmc.c has:

#ifndef MMCR0_PMA0
#define MMCR0_PMA0     0

This one took a while to find.  Unfortunately its the wrong define
(number 0 vs letter O). Its probably worth removing this override, since
if our includes get screwed up we will have the same (hard to debug)
failure.

Fix it simply for now, so that we can backport to stable.

      [POWERPC] Add missing pmc_type fields in cpu_table · 2fae4985
      由 Anton Blanchard 提交于 
      A number of cpu_table entries were missing the pmc_type field,
which means that the sysfs entries for the performance monitor
counters don't get created.  This adds them.

      [POWERPC] Fix smp_call_function to be preempt-safe · d3fdaed9
      由 Hugh Dickins 提交于 
      smp_call_function_map() was not safe against preemption to another
cpu: its test for removing self from map was outside the spinlock.
Rearrange it a little to fix that.

smp_call_function_single() was also wrong: now get_cpu() before
excluding self, as other architectures do.

      Detach sched.h from mm.h · e8edc6e0
      由 Alexey Dobriyan 提交于 
      First thing mm.h does is including sched.h solely for can_do_mlock() inline
function which has "current" dereference inside. By dealing with can_do_mlock()
mm.h can be detached from sched.h which is good. See below, why.

This patch
a) removes unconditional inclusion of sched.h from mm.h
b) makes can_do_mlock() normal function in mm/mlock.c
c) exports can_do_mlock() to not break compilation
d) adds sched.h inclusions back to files that were getting it indirectly.
e) adds less bloated headers to some files (asm/signal.h, jiffies.h) that were
   getting them indirectly

Net result is:
a) mm.h users would get less code to open, read, preprocess, parse, ... if
   they don't need sched.h
b) sched.h stops being dependency for significant number of files:
   on x86_64 allmodconfig touching sched.h results in recompile of 4083 files,
   after patch it's only 3744 (-8.3%).

Cross-compile tested on

	all arm defconfigs, all mips defconfigs, all powerpc defconfigs,
	alpha alpha-up
	arm
	i386 i386-up i386-defconfig i386-allnoconfig
	ia64 ia64-up
	m68k
	mips
	parisc parisc-up
	powerpc powerpc-up
	s390 s390-up
	sparc sparc-up
	sparc64 sparc64-up
	um-x86_64
	x86_64 x86_64-up x86_64-defconfig x86_64-allnoconfig

as well as my two usual configs.
