Linus Torvalds 71f777ed50 ARM: SoC fixes for 3.13 merge window
A first set of batches of fixes for 3.13. The diffstat is large mostly
 because we're adding a defconfig for a family that's been lacking it, and
 there's some missing clock information added for i.MX and OMAP.
 
 The at91 new code is around dealing with RTC/RTT reset at boot to fix possible
 hangs due to pending wakeup interrupts coming in during early boot.

Srinivas Kandagatla d6f67eb787 ARM: STi: remove sti_secondary_start from INIT section.
This patch removes sti_secondary_start from _INIT section, there are 2
reason for this removal.
 1. discarding such a small code does not save much, given the RAM
sizes.
 2. Having this code discarded, creates corruption issue when we boot
smp-kernel with nrcpus=1 or with single cpu node in DT.

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.
