Merge branch 'for-linus' of git://git.linaro.org/people/rmk/linux-arm
Pull ARM updates from Russell King:
"This contains the usual updates from other people (listed below) and
the usual random muddle of miscellaneous ARM updates which cover some
low priority bug fixes and performance improvements.
I've started to put the pull request wording into the merge commits,
which are:
- NoMMU stuff:
This includes the following series sent earlier to the list:
- nommu-fixes
- R7 Support
- MPU support
I've left out the ARCH_MULTIPLATFORM/!MMU stuff that Arnd and I
were discussing today until we've reached a conclusion/that's had
some more review.
This is rebased (and re-tested) on your devel-stable branch because
otherwise there were going to be conflicts with Uwe's V7M work now
that you've merged that. I've included the fix for limiting MPU to
CPU_V7.
- Huge page support
These changes bring both HugeTLB support and Transparent HugePage
(THP) support to ARM. Only long descriptors (LPAE) are supported
in this series.
The code has been tested on an Arndale board (Exynos 5250).
- LPAE updates
Please pull these miscellaneous LPAE fixes I've been collecting for
a while now for 3.11. They've been tested and reviewed by quite a
few people, and most of the patches are pretty trivial. -- Will Deacon.
- arch_timer cleanups
Please pull these arch_timer cleanups I've been holding onto for a
while. They're the same as my last posting, but have been rebased
to v3.10-rc3.
- mpidr linearisation (multiprocessor id register - identifies which
CPU number we are in the system)
This patch series that implements MPIDR linearization through a
simple hashing algorithm and updates current cpu_{suspend}/{resume}
code to use the newly created hash structures to retrieve context
pointers. It represents a stepping stone for the implementation of
power management code on forthcoming multi-cluster ARM systems.
It has been tested on TC2 (dual cluster A15xA7 system), iMX6q,
OMAP4 and Tegra, with processors hitting low-power states requiring
warm-boot resume through the cpu_resume code path"
