This is my first pull request since taking on maintenance for the

So when hot-plugging CPU and assigning new CPU number to hot-added CPU,
the mask has wrong value. The mask is used by CSF schduler to create

VM uses nr_swap_pages as one of information when it does
anonymous reclaim so that VM is able to throttle amount of swap.
Normally, the nr_swap_pages is equal to freeable space of swap disk
but for zram, it doesn't match because zram can limit memory usage
by knob(ie, mem_limit) so although VM
Currently, swap_slot_free_notify is used for zram to free
duplicated copy page for memory efficiency when it knows
there is no reference to the swap slot.
Let's extend it to be able to use it for other purpose
so this patch generalizes it so that zram can get more hints
from VM.
Signed-off-by:
VM uses nr_swap_pages as one of information when it reclaims
anonymous page because nr_swap_pages means how many freeable
space in swap so VM is able to throttle swap out if it found
there is no more space in swap.
But for zram-swap, there is size gap between virtual disksize
and physical memory
This patch implement SWAP_GET_FREE handler in zram so that VM can
know how many zram has freeable space.
VM can use it to stop anonymous reclaiming once zram is full.

Changing the rate of a "slow" clock can take 10s of milliseconds
while changing the rate of a "fast" clock can be done in a few
microseconds. With one prepare mutex a task that's trying to
change the rate of a fast clock may have to wait for a slow
clock's rate to change before it can proceed.
The prepare mutex in the common clock framework can lead to tasks waiting a
long time for other tasks to finish a frequency switch or prepare/unprepare
step. In my particular case I have a clock controlled by a co-processor that
can take 10s of milliseconds to change rate. I've seen scenarios
In the near future we're going to move the prepare lock to a
per-clock ww_mutex. Use the lockless functions here for printing
the rate and accuracy so that we don't run into AA deadlocks in
the future.

When we move this code to use ww_mutex we'll need to call
__clk_get_rate() and __clk_get_accuracy(), instead of their
non-underscore counterparts, while holding the clock's prepare
mutex. Move the recalculation of these values into the underscore
functions so that we can call __clk_get_rate() and
In the near future we're going to move the prepare lock to be a
per-clock ww_mutex. __clk_lookup() is called very deep in the
set-rate path and we would like to avoid having to take all the
locks in the clock tree to search for a clock (basically
defeating the purpose of introducing per-clock

Hi, Jean-Michel
Some platforms which using Samsung exynos SoC, we write u-boot related

Tested by plugging a Logitech ConferenceCam C3000e USB camera
and controlling pan/tilt from the userspace using the VIDIOC_S_CTRL ioctl.
Verified that it can pan and tilt at

When CONFIG_PM_DEBUG=y, we provide a sysfs file (/sys/power/pm_test) for

git-grep reveals that hwdrv_apci1500.c is the only file in comedi that uses
dev->hw_dev in calls to dev_{err,warn}(). The rest of the drivers pass
dev->class_dev to these macros instead. Switch the dev_warn() calls in
this driver to use dev->class_dev as well, for consistency.
