From: Stephen Warren <swarren@xxxxxxxxxx>
Macro __INIT is used to place various code in head-common.S into the init
section. This should be matched by a closing __FINIT at the end of the
code destined for the init section. Add this missing macro.
This historically caused no problem, because macro __CPUINIT was used at
the exact location where __FINIT was missing, which then placed following
code into the cpuinit section. However, with commit 22f0a2736 "init.h:
remove __cpuinit sections from the kernel" applied, __CPUINIT becomes a
no-op, thus leaving all this code in the init section, rather than the
regular text section. This caused issues such as secondary CPU boot
failures or crashes.

v2: Moved __FINIT after lookup_processor_type, to correctly match the
location of __CPUINIT.
Russell, I assume I should add this to the ARM patch tracker.
This version is based on v3.10.
