Merge branch 'next' of git://git.kernel.org/pub/scm/linux/kernel/git/benh/powerpc
Pull main powerpc updates from Ben Herrenschmidt:
"This time around, the powerpc merges are going to be a little bit more
complicated than usual.
This is the main pull request with most of the work for this merge
window. I will describe it a bit more further down.
There is some additional cpuidle driver work, however I haven't
included it in this tree as it depends on some work in tip/timer-core
which Thomas accidentally forgot to put in a topic branch. Since I
didn't want to carry all of that tip timer stuff in powerpc -next, I
setup a separate branch on top of Thomas tree with just that cpuidle
driver in it, and Stephen has been carrying that in next separately
for a while now. I'll send a separate pull request for it.
Additionally, two new pieces in this tree add users for a sysfs API
that Tejun and Greg have been deprecating in drivers-core-next.
Thankfully Greg reverted the patch that removes the old API so this
merge can happen cleanly, but once merged, I will send a patch
adjusting our new code to the new API so that Greg can send you the
removal patch.
Now as for the content of this branch, we have a lot of perf work for
power8 new counters including support for our new "nest" counters
(also called 24x7) under pHyp (not natively yet).
We have new functionality when running under the OPAL firmware
(non-virtualized or KVM host), such as access to the firmware error
logs and service processor dumps, system parameters and sensors, along
with a hwmon driver for the latter.
There's also a bunch of bug fixes accross the board, some LE fixes,
and a nice set of selftests for validating our various types of copy
loops.
On the Freescale side, we see mostly new chip/board revisions, some
clock updates, better support for machine checks and debug exceptions,
etc..."
