asm-generic/barrier.h defines a nop() macro. To be able to use this header on ia64, we shouldn't call local functions/variables nop(). There's one instance where this breaks on ia64: rename the function to iosapic_nop to avoid the conflict. Signed-off-by: Michael S.

...f next ac_timer on x86. Higher precision lapic timer can trigger ac_timer more precisely than simply done in PIT interrupt handler. That works perfectly on x86 because PIT is already dedicated to update system time and wall time, etc. However on IA64, there''s only one timer source (local sapic timer), to cover both updating time related statistics and triggering ac_timer softirq. In this case, the delta between adjacent timer interrupts can''t be changed dynamically, or else system time (especially NOW()) is inaccurate. So reprogram_ac_timer should always return 1 on IA64. To m...
