[PATCH 0/40] Complete set of clocksource/sched_clock patches

[Russell King - ARM Linux]

Here is the entire set of clocksource and sched_clock patches which
have been previously posted.  There's a couple of small tweaks in a
few of the patches (such as adding notrace to OMAP clocksource read
functions), and this also shows the proper ordering of these patches.

Still looking for acks or tested-by's for these patches.

[PATCH 08/40] ARM: MSM: update clock source registration

[Russell King - ARM Linux]

In d7e81c2 (clocksource: Add clocksource_register_hz/khz interface) new
interfaces were added which simplify (and optimize) the selection of the
divisor shift/mult constants.  Switch over to using this new interface.

Hi Russell,

Sorry for late feedback. Tested the branch 'clksrc' on Littleton/PXA3xx,
seems to be good.

Ok, I'll add that to the PXA and generic patches, thanks.

I'm afraid you're too late - it's already in mainline so your ack can't
be added.
