We've encountered a particular platform that under some circumstances
always has the power fault detected status raised. The pciehp irq handler
would loop forever because it thinks it is handling new events when in
fact the power fault is not new. This patch fixes that by masking off
the power faul

Since f2545b2d4ce1 ("jump_label: Reorder hotplug lock and
jump_label_lock"), it has become impossible to switch a static key

As using the normal static key API under the hotplug lock is
pretty much impossible, let's provide a variant of some of them
that require the hotplug lock to have already been taken.
These function are only meant to be used in CPU hotplug callbacks.

The Timer/PWM Module (TPM) supports input capture, output compare,
and the generation of PWM signals to control electric motor and power
management applications. The counter, compare and capture registers
are clocked by an asynchronous clock that can remain enabled in low
power modes. TPM can suppo

IMX Timer/PWM Module (TPM) supports both timer and pwm function while
this patch only adds the timer support. PWM would be added later.
The TPM counter, compare and capture registers are clocked by an
asynchronous clock that can remain enabled in low power modes.
NOTE: We observed in a very small

There is enough space to not use acronyms in the commit subject line.

Hi Peter,

Sorry for the mistake. It should be CFS.

Yes, so that the inc is a load-store, and thus
There is no enough error handling in block device adding/registration
path, for example,
device_add_disk()
blk_register_queue()
When kernel returns from device_add_disk(), no return value to tell
us it was successful or not --- that suggests it would always succeed,
and according to this assump

This patch is created to solve CamelCase issue. The
members 'IEs' and 'IELength' of struct wlan_bssid_ex
are modified to 'ies' and 'ielength' to solve CamelCase.
And all the places where these variables are referenced
inside rtl8188eu driver are also changed.
