Re: [GIT PULL] x86/apic changes for v2.6.38

[Luck, Tony]

Untested on X86.  Builds and boots on ia64 (both normally and with
maxcpus=8 to limit the number of cpus).

I left the comment ... though it might need some tweaking as it is
kind of tenuously connected to the '0' argument passed to acpi_table_parse_srat.
