This patch proposes a system-wide sysctl-aware default for the
high-resolution timer slack value, which may be changed from 0
to HRTIMER_MAX_SLACK nanoseconds. Default system-wide and per-task
values are HRTIMER_DEFAULT_SLACK. Per-task value isn't inherited
across fork(); instead, newborn task
Use ZERO_OR_NULL_PTR allocation pointer checking where allocation
function may return ZERO_SIZE_PTR.

Hi Mark,
Here is a consolidated series which adds DT support for twl regulator
driver and adds support for VDD1/2/3 regulator and support for
fixed LDO V1V8 and V2V1. The patches are based on -next and tested
on omap3 beagle and omap4 panda boards.
I have dropped the patch updating the dts

To be able to attach consumers to these supplies from board
files we need to have regulator_init_data for them.

Not a strong reason. I thought making it an inline would introduce
slightly less new execution when adding this code (realizing that

The two patches were originally in [PATCH V6 0/7] add a generic cpufreq driver.
I seperated them and hope they can go to upstream earlier.
Richard Zhao (2):
ARM: add cpufreq transiton notifier to adjust loops_per_jiffy for smp
cpufreq: OMAP: remove loops_per_jiffy recalculate for smp
If CONFIG_SMP, cpufreq skips loops_per_jiffy update, because different
arch has different per-cpu loops_per_jiffy definition.
