Re: [PATCH v3 1/3] alpha: Use OPTIMIZE_INLINING instead of asm/compiler.h

Use CONFIG_ARCH_SUPPORTS_OPTIMIZED_INLINING and CONFIG_OPTIMIZE_INLINING
instead of undefining the inline macros in the alpha specific
asm/compiler.h. This is to allow asm/compiler.h to become a general
header that can be used for overriding linux/compiler*.h.

A build of alpha's defconfig on GCC 7.3 before and after this series
(i.e. this commit and "compiler.h: Allow arch-specific overrides" which
includes asm/compiler.h from linux/compiler_types.h) results in the
following size differences, which appear harmless to me:

Looks fine to me.

Should I take it through the alpha tree?
