      spi/omap2_mcspi.c: Force CS to be in inactive state after off-mode transition · 42ce7fd6
      Gregory CLEMENT authored 
      
When SPI wake up from OFF mode, CS is in the wrong state: force it to the
inactive state.

During the system life, I monitored the CS behavior using a oscilloscope.
I also activated debug in omap2_mcspi, so I saw when driver disable the clocks
and restore context when device is not used.Each time the CS was in the correct
state.  It was only when system was put suspend to ram with off-mode activated
that on resume the CS was in wrong state( ie activated).

Changelog:
* Change from v1 to v2:
  - Rebase on linus/master (after 2.6.37-rc1)
  - Do some clean-up and fix indentation on both patches
  - Add more explanations for patch 2

* Change from v2 to v3:
  - Use directly resume function of spi_master instead of using function
  - from spi_device as Grant Likely pointed it out.
  - Force this transition explicitly for each CS used by a device.

* Change from v3 to v4:
  - Patch clean-up according to Kevin Hilman and checkpatch.
  - Now force CS to be in inactive state only if it was inactive when it was
    suspended.

* Change from v4 to v5:
  - Rebase on linus/master (after 2.6.37-rc3)
  - Collapse some lines as pointed by Grant Likely
  - Fix a spelling

* Change from v5 to v6:
  - Rebase on linus/master (after 2.6.37-rc7)
  - Use CONFIG_SUSPEND instead of CONFIG_PM
  - Didn't use legacy PM methods anymore. Instead, add a struct dev_pm_ops and
    add the resume method there.
  - Fix multi-line comment style

* Change from v6 to v7:
  - Rebase on linus/master (after 2.6.37-rc8)
  - Drop an extra line

      pata_cs5536: avoid implicit MSR API inclusion on x86-64 · ff5dd32b
      Jeff Garzik authored 
      We don't need or want MSR usage here, on x86-64.
x86-64 was disabled intentionally in Kconfig, but commit
9272dcc2

 changed that.

      ACPI / ACPICA: Disable GPEs during initialization · 5acdb1af
      Rafael J. Wysocki authored 
      GPEs with corresponding _Lxx/_Exx control methods need to be disabled
during initialization in case they have been enabled by the BIOS, so
that they don't fire up until they are enabled by acpi_update_gpes().
