[PATCH 0/5] Convert ARM subarchitectures to generic wfi macro.

[PATCH 0/5] Convert ARM subarchitectures to generic wfi macro.

[Nick Bowler]

This series cleans up all remaining ARM subarchitectures that I could
find to use the generic wfi macro.  As I don't have any of the boards in
question, I've only compile-tested these patches to the extent that I
was able.

See the previous discussion in https://lkml.org/lkml/2011/8/19/433 for
more background.

Nick Bowler (5):
  ARM: realview: Use wfi macro in platform_do_lowpower.
  ARM: exynos4: Use wfi macro in platform_do_lowpower.
  ARM: shmobile: Use wfi macro in platform_cpu_die.
  ARM: tegra: Use wfi macro in platform_do_lowpower.
  ARM: omap4: Kill private do_wfi macro.

[PATCH 1/5] ARM: realview: Use wfi macro in platform_do_lowpower.

[Nick Bowler]

Current Realview CPU hotplug code includes a hardcoded WFI instruction,
in ARM encoding.  The hardcoded instruction is both hard to understand
and doomed to failure when building the kernel in Thumb-2 mode.
