When implementing movablemem_map boot option, we introduced an array
movablemem_map.map[] to store the memory ranges to be set as ZONE_MOVABLE.
Since ZONE_MOVABLE is the latst zone of a node, if user didn't specify
the whole node memory range, we need to extend it to the node end so that
we can
We now provide an option for users who don't want to specify physical
memory address in kernel commandline.

* SRAT:|_| |_| |_| |_| ..

Here, we do two things:
1) patch1 ~ patch2: Prevent memblock from allocating memory in memory
to be set as ZONE_MOVABLE.
2) patch3: Provide movablemem_map=acpi option for users who
don't want to specify physical address in kernel
On linux, the pages used by kernel could not be migrated. As a result,
if a memory range is used by kernel, it cannot be hot-removed. So if
we want to hot-remove memory, we should prevent kernel from using it.
The way now used to prevent this is specify a memory range by

As Michael mentioned, set affinity and select queue will not work very
well when CPU IDs are not consecutive, this can happen with hot unplug.
Fix this bug by traversal the online CPUs, and create a per cpu variable
to find the mapping from CPU to the preferable virtual-queue.
Cc: Rusty Russell
Add a cpu notifier to virtio-net, so that we can reset the
virtqueue affinity if the cpu hotplug happens. It improve
the performance through enabling or disabling the virtqueue
affinity after doing cpu hotplug.

For anyone who cares about resource control setting up the memory
control group in combination with user namespaces is strongly
recommended.
User namespaces are a particular problem when it comes to resource
control. Not all of the resources you can create with a user namespace

Ok, I redid them against tip:x86/cpu and am running build tests. Will

The platform data is used not only by wlcore-based drivers, but also
by wl1251. Move it up in the directory hierarchy to reflect this.
Additionally, make it truly optional. At the moment, disabling
platform data while wl1251_sdio or wlcore_sdio are enabled doesn't
work, but it will be necessary

I think it would be better to have INIT_LIST_HEAD() during @entry
initialization.
Hello,
When using the leds-pwm module with external PWM chips connected through
I2C, the kernel will panic when settings a trigger. In this case, PWM
calls can sleep, and should be deferred.
Patch 1 and 2 add the necessary API to the PWM subsystem, and update
matching drivers.
Patch 3 updates
Calls to some external PWM chips can sleep. To help users,
add pwm_cansleep() API.

Call to led_pwm_set() can happen inside atomic context, like triggers.
If the PWM call can sleep, defer using a worker.

In case of the fixed speed set up for NIC
(e.g. ethtool -s eth0 autoneg off speed 100 duplex full)
with ethernet cable plugged off, mentioned algorithm
slows down NIC speed, so the further hooking up gives
no result. AFAIK, this behaviour
