ACPI-CA update patch for review

[Matthew Dillon]

:Does that apply to ioctl or sysctl support code, too?  Can you shed
:some light on me to find how it's guaranteed?

:Thanks.

    The ACPI idle code is disabled on SMP boxes.   Line 838 of acpi_cpu.c.

    Hmm.  I don't see any specific code to force us onto cpu #0 for ioctls
    or sysctls, but those do certainly run under the BGL.  It would be
    fairly easy to force those to run on cpu #0 if it turned out we needed
    to.
