Subject: [PATCH] x86: fix section mismatch warning in process_*.c

Fix the following warning:
WARNING: arch/x86/kernel/built-in.o(.text+0x3): Section mismatch: reference to .cpuinit.data:force_mwait in 'mwait_usable'
[Seen on 64 bit only but similar pattern exist on 32 bit so fix it there too]

mwait_usable() were only used by a function annotated __cpuinit
so annotate mwait_usable() with __cpuinit to fix the warning.
