For those of you eager to try the bk tree: now might be a good time to
try it out. The current tree Works For Me.
Jes, I applied the gettimeoffset patch, but also consolidated it with
the last_nsec_offset. It didn't make sense to me to have both of them
in the generic kernel, when they were basically doing the same thing.
I compensated for this change by having the SN2 update/reset_wall_time
hooks call the generic ia64 hooks first. You may want to retest to
make sure it all works as expected.
Oh, I also measured the effect of the additional sal_platform_features
check in the fast gettimeofday(): the cold cache case is definitely a
bit slower and more variable (as you'd expect), but the warm cache
case continues to run at 130 cycles, which is nice.
