The 32 bit sched_clock interface now supports 64 bits. Upgrade to
the 64 bit function to allow us to remove the 32 bit registration
interface. Also mark the read function notrace since we're here
and failure to do so would cause ftrace to break.

The 32 bit sched_clock interface now supports 64 bits. Upgrade to
the 64 bit function to allow us to remove the 32 bit registration

Just to clarify, are the dependencies in v3.12? or were they merged for
the v3.13 merge window and just recently it Linus' tree.

The dependencies are not in 3.12. They just hit Linus' tree this merge
window (3.13). Ingo brought it into tip at commit
68e90740284c69292881cd38c7ece6f09a18a58f and Linus took it at commit
87093826aa0172d9135ca1f301c4298a258ceee6.

OK, thanks for the clarification.
I've applied these to an soc/sched_clock branch which is based on
tip/timers-core-for-linus and merged it into our to-build branch so it
gets some early boot/build coverage. Once -rc1 is out, we'll start
adding non-fixes to for-next and this will be among the first branches
there (assuming the build/boot doesn't show any problems.)
