This prepares to move CONFIG_OPTIMIZE_INLINING from x86 to a common
place. We need to eliminate potential issues beforehand.
If it is enabled for arm, Clang build results in the following modpost
warning:
WARNING: vmlinux.o(.text+0x1124): Section mismatch in reference from the function setup_machine_tags() to the function .init.text:early_print()
The function setup_machine_tags() references
the function __init early_print().
This is often because setup_machine_tags lacks a __init
annotation or the annotation of early_print is wrong.
