+ p8, p0=0, r2
+(p8)	br.spnt.many fsys_fallback_syscall

can be shortened to: p8, p0=IA64_SAL_PLATFORM_FEATURE_ITC_DRIFT_BIT, r2
(p8)	br.spnt.many fsys_fallback_syscall

Might make it a bit easier to schedule things around (just add foo_BIT
numbers for all the SAL_PLATFORM_FEATURE bits and then define the
masks in terms of these bit numbers).

Sorry I didn't catch this previously.
