commit ac7c3e4ff401b304489a031938dbeaab585bfe0a
Author: Masahiro Yamada <yamada.masahiro@xxxxxxxxxxxxx>

    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 'inline'.
    
    This is not a problem for x86 since it has been long used by
    arch/x86/configs/{x86_64,i386}_defconfig.
    
    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.
