Subject[PATCH 1/7] x86, xsave: fix section mismatch warning - setup_xstate_init
setup_xstate_init calls __init function (alloc_bootmem) and is called only
from __init function (xsave_cntxt_init), so mark it static __init

WARNING: vmlinux.o(.text+0x8f7b): Section mismatch in reference from the function setup_xstate_init() to the function .init.text:__alloc_bootmem()
The function setup_xstate_init() references
the function __init __alloc_bootmem().
This is often because setup_xstate_init lacks a __init
annotation or the annotation of __alloc_bootmem is wrong.
