well, while i agree with the patch it could make things worse. In this
case it can cause code that has been compiled to rely on TSC to
malfunction. For if sched_clock() was using cpu_has_tsc it could return
0 all the time, breaking the scheduler without the user having a clear
idea why it broke. It isnt, and sched_clock() will work fine, but still,
your "this cant make things worse" statement is not completely correct.
In any case:
Acked-by: Ingo Molnar <mingo at elte.hu>
and i've also queued it up into the for-.25 queue of x86.git.
