[PATCH] linux-2.5.69_subarch-fix_A0.patch

[john stultz]

All,
	This patch fixes a circular dependency (a function in mach_apic.h
requires hard_smp_processor_id() and hard_smp_processor_id() requires
macros from mach_apic.h) that has been in the subarch code for a bit,
but was hacked around with some #ifdefs. 

With the inclusion of the generic-subarch the hack was dropped and
bigsmp and summit promptly broke. So this makes things compile again. 

thanks
-john
