    x86/HPET: fix initialization order
    At least the legacy path can enter its interrupt handler callout while
    initialization is still in progress - that handler checks whether
    ->event_handler is non-NULL, and hence all other initialization must
    happen before setting this field.
    Do the same to the MSI initialization just in case (and to keep the
    code in sync).

    x86: Fix cpu offline bug: add clflush inside dead loop
    At some platform (like Xen 7400), when hyperthreading, an offlined
    thread may waked spuriously up by its brother, and returning around
    the loop.  This patch explicitly clflush the cache line in a light
    weight way to workaround potential issue.  Unlike wbinvd, clflush is
    not serializing instruction, hence memory fence is necessary to make
    sure all load/store operation visible before flush cache line.

    x86: Fix cache flush bug of cpu offline
    Current xen cpu offline logic flush cache too early, which potentially
    break cache coherency.  wbinvd should be the last ops before cpu going
    into dead, otherwise cache may be dirty, i.e, something like setting
    an A bit on page tables. Pointed out by Arjan van de Ven.

    x86: Fix cpu offline bug: cancel SYSIO method when play dead
    Play dead is a fragile and tricky point of cpu offline logic.  For how
    to play cpu dead, linux kernel changed several times: Very old kernel
    support 3 ways to play cpu dead: mwait, SYSIO, and halt, just like
    what cpuidle did when enter C3; Later, it cancel mwait and SYSIO
    support, only use halt to play dead; Latest linux 2.6.38 add mwait
    support when cpu dead.
    This patch cancel SYSIO method when cpu dead, keep same with latest
    SYSIO is an obsoleted method to enter deep C, with some tricky
    hardware behavior, and seldom supported in new platform.  Xen
    experiment indicate that when cpu dead, SYSIO method would trigger
    unknown issue which would bring strange error.  We now cancel SYSIO
    method when cpu dead, after all, correctness is more important than
    power save, and btw new platform use mwait.
