Hi Greg,
I am sending extra patches on omap-thermal driver, under staging.
There are couple of fixes based on Dan Carpenter's review on
the last patch set I sent. On top of these, there are some
changes on the naming convention for this driver. This rename
is based on previous review cycles that

This patch changes the data structures of this driver so
that readonly data can reside only in the conf pointer.
Now each register has a struct to hold its configuration info,
to be used base on chip version for instance, and a
struct of values to be written, like register shadow and priv data.
This patch updates the documentation to remove
all warnings and errors reported by scripts/kernel-doc.
Most are missing arguments due to wrong format.

In order to save power, it would be useful to schedule light weight work on cpus
that aren't IDLE instead of waking up an IDLE one.
By idle cpu (from scheduler's perspective) we mean:
- Current task is idle task
- nr_running == 0
- wake_list is empty
This is already implemented for timers as
Check for current cpu's idleness is already done in implementation of
sched_select_cpu() which is called by get_nohz_timer_target(). So, no need to
call idle_cpu() twice, once from sched_select_cpu() and once from timer and
hrtimer before calling get_nohz_timer_target().
This patch removes calls
queue_work() queues work on current cpu. This may wake up an idle CPU, which is
actually not required.
Some of these works can be processed by any CPU and so we must select a non-idle
CPU here. The initial idea was to modify implementation of queue_work(), but
that may end up breaking lots of
Phylib uses workqueues for multiple purposes. There is no real dependency of
scheduling these on the cpu which scheduled them.
On a idle system, it is observed that and idle cpu wakes up many times just to

In order to save power, it would be useful to schedule light weight work on cpus
that aren't IDLE instead of waking up an IDLE one.
By idle cpu (from scheduler's perspective) we mean:
- Current task is idle task
- nr_running == 0
- wake_list is empty
This is already implemented for timers as

Booting with 32 TBytes memory hits BUG at mm/page_alloc.c:552! (output below).
The key hint is "page 4294967296 outside zone".
4294967296 = 0x1 (bit 32 is set).
The problem is in include/linux/mmzone.h:
530 static inline unsigned zone_end_pfn(const struct zone *zone)
531 {

I figured the main reason to add this warning was to prevent people to

This keyboard backlight device causes a 10 second delay to boot. Add it
to the quirk list with HID_QUIRK_NO_INIT_REPORTS.

Okay, so I think that for 3.9 we want the patch below, and if eventually
hardware root cause / workaround is found for GM45, we can have it merged
