KVM fixes for 3.11

On the x86 side, there are some optimizations and documentation updates.
The big ARM/KVM change for 3.11, support for AArch64, will come through
Catalin Marinas's tree.  s390 and PPC have misc cleanups and bugfixes.

There is a conflict due to "s390/pgtable: fix ipte notify bit" having
entered 3.10 through Martin Schwidefsky's s390 tree.  This pull request
has additional changes on top, so this tree's version is the correct one.

Power management and ACPI updates for 3.11-rc1

- Hotplug changes allowing device hot-removal operations to fail
  gracefully (instead of crashing the kernel) if they cannot be
  carried out completely.  From Rafael J Wysocki and Toshi Kani.

- Freezer update from Colin Cross and Mandeep Singh Baines targeted
  at making the freezing of tasks a bit less heavy weight operation.

- cpufreq resume fix from Srivatsa S Bhat for a regression introduced
  during the 3.10 cycle causing some cpufreq sysfs attributes to
  return wrong values to user space after resume.

- New freqdomain_cpus sysfs attribute for the acpi-cpufreq driver to
  provide information previously available via related_cpus from
  Lan Tianyu.

- cpufreq fixes and cleanups from Viresh Kumar, Jacob Shin,
  Heiko Stübner, Xiaoguang Chen, Ezequiel Garcia, Arnd Bergmann, and
  Tang Yuantian.

- Fix for an ACPICA regression causing suspend/resume issues to
  appear on some systems introduced during the 3.4 development cycle
  from Lv Zheng.

- ACPICA fixes and cleanups from Bob Moore, Tomasz Nowicki, Lv Zheng,
  Chao Guan, and Zhang Rui.

- New cupidle driver for Xilinx Zynq processors from Michal Simek.

- cpuidle fixes and cleanups from Daniel Lezcano.

- Changes to make suspend/resume work correctly in Xen guests from
  Konrad Rzeszutek Wilk.

- ACPI device power management fixes and cleanups from Fengguang Wu
  and Rafael J Wysocki.

- ACPI documentation updates from Lv Zheng, Aaron Lu and Hanjun Guo.

- Fix for the IA-64 issue that was the reason for reverting commit
  9f29ab1 and updates of the ACPI scan code from Rafael J Wysocki.

- Mechanism for adding CMOS RTC address space handlers from Lan Tianyu
  (to allow some EC-related breakage to be fixed on some systems).

- Spec-compliant implementation of acpi_os_get_timer() from
  Mika Westerberg.

- Modification of do_acpi_find_child() to execute _STA in order to
  to avoid situations in which a pointer to a disabled device object
  is returned instead of an enabled one with the same _ADR value.
  From Jeff Wu.

- Intel BayTrail PCH (Platform Controller Hub) support for the ACPI
  Intel Low-Power Subsystems (LPSS) driver and modificaions of that
  driver to work around a couple of known BIOS issues from
  Mika Westerberg and Heikki Krogerus.

- EC driver fix from Vasiliy Kulikov to make it use get_user() and
  put_user() instead of dereferencing user space pointers blindly.

- Assorted ACPI code cleanups from Bjorn Helgaas, Nicholas Mazzuca and
  Toshi Kani.

- Modification of the "runtime idle" helper routine to take the return
  values of the callbacks executed by it into account and to call
  rpm_suspend() if they return 0, which allows some code bloat
  reduction to be done, from Rafael J Wysocki and Alan Stern.

- New trace points for PM QoS from Sahara <keun-o.park@windriver.com>.

- PM QoS documentation update from Lan Tianyu.

- Assorted core PM code cleanups and changes from Bernie Thompson,
  Bjorn Helgaas, Julius Werner, and Shuah Khan.

- New devfreq driver for the Exynos5-bus device from Abhilash Kesavan.

- Minor devfreq cleanups, fixes and MAINTAINERS update from
  MyungJoo Ham, Abhilash Kesavan, Paul Bolle, Rajagopal Venkat, and
  Wei Yongjun.

- OMAP Adaptive Voltage Scaling (AVS) SmartReflex voltage control
  driver updates from Andrii Tseglytskyi and Nishanth Menon.

KVM/ARM pull request for 3.11 merge window

Late power management and ACPI fixes for 3.10

- Fix for an ACPI dock regression introduced by the recent rework of
  the ACPI-based PCI hotplug code (acpiphp) that caused it to be
  initialized before the ACPI dock driver from Jiang Liu.

- Fix for PCI resources allocation in the ACPI-based PCI hotplug code
  (acpiphp) that makes it use the same PCI resources assignment rules
  during runtime hotplug that are used during boot from Jiang Liu.

- Fix for ordering and synchronization issues during hot-removal of
  PCI devices on docking stations from Rafael J Wysocki.

- Fix for a regression that removed the code to register a hotplug
  notificaion handler for for ATA ports/devices inadvertently from
  Aaron Lu.

- Fix for a recent cpufreq regression causing a NULL pointer
  dereference to trigger in od_set_powersave_bias() in some
  situations from Jacob Shin.

Now that we have a generic arch hook for broadcast we can remove the local
timer API entirely. Doing so will reduce code in ARM core, reduce the
architecture dependencies of our timer drivers, and simplify the code because
we no longer go through an architecture layer that is essentially a hotplug
notifier.

MSM clock updates for 3.11.

Per Stephen Boyd's coverletter:

Resending to collect higher level maintainer acks per Olof's request.
The plan is to push this patchset through MSM to the arm-soc tree.

This patchset moves the existing MSM clock code and affected drivers
to the common clock framework. A prerequisite of moving to the common
clock framework is to use clk_prepare() and clk_enable() so the first
few patches migrate drivers to that call (clk_prepare() is a no-op on
MSM right now). It also removes some custom clock APIs that MSM
provides and finally moves the proc_comm clock code to the common
struct clk.

This patch series will be used as the foundation of the MSM 8660/8960
clock code that I plan to send out after this series.

Linux 3.10-rc7

ACPI fixes for 3.10-rc7

- Fix for a regression causing a failure to turn on some devices on
  some systems during initialization introduced by a recent revert of
  an ACPI PM change that broke something else.

- ACPI power resources initialization fix preventing a NULL pointer
  from being dereferenced in the acpi_add_power_resource() error code
  path.

- ACPI dock station driver fix that adds missing locking to
  write_undock().

- ACPI resources allocation fix changing the scope of an old
  workaround so that it doesn't affect systems that aren't actually
  buggy.
