Subject[PATCH] compiler: enable CONFIG_OPTIMIZE_INLINING forcibly
Commit 9012d011660e ("compiler: allow all arches to enable
CONFIG_OPTIMIZE_INLINING") allowed all architectures to enable
this option. A couple of build errors were reported by randconfig,
but all of them have been ironed out.

Towards the goal of removing CONFIG_OPTIMIZE_INLINING entirely
(and it will simplify the 'inline' macro in compiler_types.h),
this commit changes it to always-on option. Going forward, the
compiler will always be allowed to not inline functions marked

This is not a problem for x86 since it has been long used by

I am keeping the config option just in case any problem crops up for
other architectures.

The code clean-up will be done after confirming this is solid.
