Subject: [PATCH] ARM: move body of head-common.S back to text section

From: Stephen Warren <swarren@...dia.com>

Commit 281ecb7 "arm: delete __cpuinit/__CPUINIT usage from all ARM
users" removed a __CPUINIT from head-common.S. However, the code
immediately before the removed tag was marked __INIT, and was missing
a match __FINIT. This caused code after the removed __CPUINIT to end
up in the init section rather than the main text section as desired.
This caused issues such as secondary CPU boot failures or crashes.
Add the missing __FINIT to solve this.
