I would like to use omap dmtimer for a PWM driver (for the backlight
on my display).
But there are two difficulties.
Unfortunately Jon Hunter (who has helped me with dmtimers before)
seems to have disappeared. So I guess I get to do it myself :-)
Following two patches make dmtimers more usable.

Sony Vaio Z1 series require "reboot=pci" for reboot and power off.
This patch is to add them machines to quirk table and set pci reboot
default.

No, I haven't had time to look at this. And frankly, I don't even have
an idea what to look for if
This is no need for dmtimer.h to be in the 'plat' include directory,
and it makes it hard to write drivers which use it (such as a
PWM driver). So move it to linux/omap-dmtimer.h.

It is perfectly appropriate to set the counter register
when the timer isn't running. The value set will be where
the counter starts counting from.

Previously, set_page_dirty is called every time after writting one summary info

To avoid redundant set_page_dirty, we only call set_page_dirty before release

Hi,
I've been working (on and off) on blk-mq for a while now, and
I think it's finally time to polish it off and get it posted
for review with inclusion for 3.13. It's fairly well contained
and these core bits should not impact any drivers. There's
a series of prep patches in front of the meat pat

Add an API to return free tags, blk-mq-tag will use it.
Note, this just returns a snapshot of free tags number. blk-mq-tag has
two usages of it. One is for info output for diagnosis. The other is to
quickly check if there are free tags for request dispatch checking.
Neither requ
A driver that simply completes IO it receives, it does no
transfers. Written to fascilitate testing of the blk-mq code.
It supports various module options to use either bio queueing,
rq queueing, or mq mode.

In my usage, sometimes the percpu APIs are called with irq locked,
sometimes not. lockdep complains there is potential deadlock. Let's
always use percpucounter lock in irq safe way. There should be no
performance penality, as all those are slow code path.

Hi,
Thanks for your review.
I resent patch v3 after removing wrong wrapping.
I made one toggle function because enable/disable functions have redundant
codes and another reviewer suggested it.
Is it better to separate it into two functions?
Thanks,
Hyunhee Kim.

Make percpu_ida percpu size/batch configurable. The block-mq-tag will
use it.
After block-mq uses percpu_ida to manage tags, performance is improved.
My test is done in a 2 sockets machine, 12 process cross the 2 sockets.
So if there is lock contention or ipi, should be stressed

This reference count has been around since before git history, but the only
place where it's used is in blk_execute_rq, and ther it is entirely useless
as it is incremented before submitting the request and decremented in the
end_io handler before waking up the submitter t
From: Shaohua Li
Add a new API to iterate free ids. blk-mq-tag will use it.
Note, this doesn't guarantee to iterate all free ids restrictly. Caller
should be aware of this. blk-mq uses it to do sanity check for request
timedout, so can tolerate the limitation.

We don't need truncate protection for block devices, so add a flag
bypassing this cache line dirtying twice for every IO. This easily
contributes to 5-10% of the CPU time on high IOPS O_DIRECT testing.

blk-mq reuses the request potentially immediately, since the most
cache hot is always given out first. This means that rq->csd could
be reused between csd->func() being called and csd_unlock() being
called. This isn't a problem, since we never use wait == 1 for
the smp call function. Add CSD_FLAG_W
