Subject: arm64: mark (__)cpus_have_const_cap as __always_inline
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 arm64, the following errors are reported:
In file included from ././include/linux/compiler_types.h:68,
from <command-line>:
