WARNING: arch/x86/kernel/built-in.o(.cpuinit.text+0x7115): Section
mismatch in reference from the function load_ucode_amd_ap() to the
function .init.text:find_ucode_in_initrd()
The function __cpuinit load_ucode_amd_ap() references
a function __init find_ucode_in_initrd().
If find_ucode_in_initrd is only used by load_ucode_amd_ap then
annotate find_ucode_in_initrd with a matching annotation.
