    Subject[patch 0/4] mm: de-skew page refcount
    The following patchset (against 2.6.16-rc1 + migrate race fixes) uses the new
    atomic ops to do away with the offset page refcounting, and simplify the race
    that it was designed to cover.

    This allows some nice optimisations, and in the page freeing path we end up
    saving 2 atomic ops including a spin_lock_irqsave in the !PageLRU case, and 1
    or 2 atomic ops in the PageLRU case.

    Andrew's previous feedback has been incorporated (less BUG_ONs in fastpaths
    and more detail in changelogs).

    Anyone spot any holes or races?
