    SubjectRe: [ACPI] Re: Linux 2.4.26-rc1 (cmpxchg vs 80386 build)
    From

    Sorry I didn't reply to this thread, after Alan wrote I figured
    the topic was closed;-)

    Yes, per my initial message, gcc _will_ generate cmpxchg for the 80386
    build. Indeed, it has been doing so for over a year with ACPI's
    previous private (and flawed) asm() invocation of cmpxchg.

    Andi/Alan suggested we invoke cmpxchg always in ACPI,
    but disable ACPI at boot-time in the unlikely event we find
    ourselves running on a cpu without that instruction.

    Luming has already taking a swing at this patch here:

    thanks,
