[Rafael J. Wysocki]

Hi Linus,

Please pull from the git repository at

  git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git pm+acpi-3.9-rc6

to receive ACPI and power management fixes for v3.9-rc6 with top-most commit
6cb437acd93a01fdbd6bac9c78ac8159c644e576

  Merge branch 'acpi-fixes' into fixes

on top of commit 07961ac7c0ee8b546658717034fe692fd12eefa9

  Linux 3.9-rc5

Included are:

- Revert of a recent cpuidle change that caused Nehalem machines
  to hang on boot from Alex Shi.

- USB power management fix addressing a crash in the port device
  object's release routine.

- Device PM QoS fix for a potential deadlock related to sysfs
  interface.

- Fix for a cpufreq crash when the /cpus Device Tree node is missing.
  From Paolo Pisati.

- Fix for a build issue on ia64 related to the fact that the
  Boot Graphics Resource Table (BGRT) is only useful on x86 with
  EFI.  From Tony Luck.

- Two fixes for ACPI handles being set incorrectly for device
  objects that don't correspond to any ACPI namespace nodes in
  the I2C and SPI subsystems.

- Fix for compiler warnings related to CONFIG_PM_DEVFREQ being
  unset from Rajagopal Venkat.

- Fix for a symbol definition typo in cpufreq_governor.h from
  Borislav Petkov.

Thanks!

      cpuidle / ACPI: recover percpu ACPI processor cstate

Borislav Petkov (1):
      cpufreq: Correct header guards typo

Paolo Pisati (1):
      cpufreq: check OF node /cpus presence before dereferencing it

Rafael J. Wysocki (4):
      USB / PM: Don't try to hide PM QoS flags from usb_port_device_release()
      PM / QoS: Avoid possible deadlock related to sysfs access
      ACPI / SPI: Use parent's ACPI_HANDLE() in acpi_register_spi_devices()
      ACPI / I2C: Use parent's ACPI_HANDLE() in acpi_i2c_register_devices()

Rajagopal Venkat (1):
      PM / devfreq: Fix compiler warnings for CONFIG_PM_DEVFREQ unset

Tony Luck (1):
      ACPI / BGRT: Don't let users configure BGRT on non X86 systems
