Ok, here's the patch that should work on all architectures (with fingers
crossed). At least the SPARC part wasn't all that difficult, since 2.3.9
already contains the necessary code. The first patch contained a big flaw,
since I mixed microseconds with nanoseconds (gettimeoffset returns
microseconds, whereas timespec is in nanoseconds). Oops. Don't know how it
slipped through my tests.
For those architectures without synced CPU tick counter (Alpha, PPC), I
just return worst case delta from gettimeoffset. I didn't yet fix the
problem with jiffies added later. And it's still a patch against 2.3.9,
even though 2.3.10 is out.
For the timer sync problem on Alpha, I suggest using an array of
state.partial_tick[MAX_CPUs], and compute that value in
smp_percpu_timer_interrupt instead of just doing it for the boot CPU. I
don't know if this sort of fix can be used for the PPC, too.
