Paul Gortmaker 8bd26e3a7e arm: delete __cpuinit/__CPUINIT usage from all ARM users
The __cpuinit type of throwaway sections might have made sense
some time ago when RAM was more constrained, but now the savings
do not offset the cost and complications.  For example, the fix in
commit 5e427ec2d0 ("x86: Fix bit corruption at CPU resume time")
is a good example of the nasty type of bugs that can be created
with improper use of the various __init prefixes.

After a discussion on LKML[1] it was decided that cpuinit should go
the way of devinit and be phased out.  Once all the users are gone,
we can then finally remove the macros themselves from linux/init.h.

Note that some harmless section mismatch warnings may result, since
notify_cpu_starting() and cpu_up() are arch independent (kernel/cpu.c)
and are flagged as __cpuinit  -- so if we remove the __cpuinit from
the arch specific callers, we will also get section mismatch warnings.
As an intermediate step, we intend to turn the linux/init.h cpuinit
related content into no-ops as early as possible, since that will get
rid of these warnings.  In any case, they are temporary and harmless.

This removes all the ARM uses of the __cpuinit macros from C code,
and all __CPUINIT from assembly code.  It also had two ".previous"
section statements that were paired off against __CPUINIT
(aka .section ".cpuinit.text") that also get removed here.

Linus Torvalds 99c6bcf46d ARM: arm-soc multiplatform updates for 3.10
More multiplatform enablement for ARM platforms. The ones converted in
 this branch are:
 - bcm2835
 - cns3xxx
 - sirf
 - nomadik
 - msx
 - spear
 - tegra
 - ux500
 
 We're getting close to having most of them converted!
 
 One of the larger platforms remaining is Samsung Exynos, and there are
 a bunch of supporting patches in this merge window for it. There was a
 patch in this branch to a early version of multiplatform conversion,
 but it ended up being reverted due to need of more bake time. The
 revert commit is part of the branch since it would have required
 rebasing multiple dependent branches and they were stable by then.

Arnd Bergmann 2b9c613c4e ARM: spear: move generic.h and pl080.h into private dir
No file outside of mach-spear includes these files any more,
so they don't have to be globally visible now.

Arnd Bergmann a7ed099ffc ARM: spear: move all files to mach-spear
There are no conflicting files between the three mach-spear* directories
and plat-spear any more, so we can now move all file to a common
mach-spear directory.
