    s390/alternatives: make use of asm_inline · cceb0183
    Heiko Carstens authored
    This is the s390 version of commit 40576e5e ("x86: alternative.h:
    use asm_inline for all alternative variants").
    
    See commit eb111869 ("compiler-types.h: add asm_inline
    definition") for more details.
    
    With this change the compiler will not generate many out-of-line
    versions for the three instruction sized arch_spin_unlock() function
    anymore. Due to this gcc seems to change a lot of other inline
    decisions which results in a net 6k text size growth according to
    bloat-o-meter (gcc 9.2 with defconfig).
    But that's still better than having many out-of-line versions of
    arch_spin_unlock().
