    SubjectRe: [PATCH] [2.5] asm-generic/atomic.h and changes to arm, parisc, mips, m68k, sh, cris to use it

    - Didn't implement atomic_{add,sub,inc,dec}_return. This is currently
    not used in the generic kernel but it can be useful.
    - Had inline assembly for things the compiler should be able to generate
    on its own
    - Didn't work on SMP (irrelevant in practice, but we already need that
    in asm-generic/atomic.h for parisc so m68k gets it for free)

    The actual assembly generated should be the same and the header is
    shorter.

    The only problem is that it may introduce bugs. Does it work on m68k?
