[PATCH v2 0/5] OMAP3: PM: Fixes for low power code

Santosh Shilimkar [off-list ref] writes:

The series does below fixes to the omap3 low power code.
	1. Use supported ARMv7 instructions instead of the legacy ones
	2. Fix the MMU on sequence
	3. Fix the cache flush scenario when only L1 lost.
	4. Remove all un-necessary context save registers
	5. Disable C-bit before cache clean

V2:
- Rebased series on top of pm-core branch where the Dave Martin's
  Thumb2 patches are merged.
- Dropped set_cr() patch since it's already merged in pm-core branch
- Fixed the hang issue reported by Kevin Hilman with OMAP3630

Thanks for the updates.

I've been testing the previous series along with Paul's integration
branch and things look good.

Will re-test with this updated version and queue for 2.6.39 (branch:
for_2.6.39/pm-misc)

Thanks,

Kevin

It's generated against latest pm-core branch and tested suspend
and cpuilde on OMAP3630 ZOOM.
