b1f048c147 staging: lustre: llite: reduce indent in ll_dir_read
Instead of making a large chunk of code conditional
based on if a page is valid we reverse the page
validity test and exit the loop if the page is invalid
instead. This allows a section of code to reduce its
indentation one level.

Port the xattr functionality to the new xattr_handler API.
This is smallest changes needed to move to this new API. The
function ll_removexattr can be replaced by generic_removexattr
as well since it also uses the xattr_handler set xattr backend.
To tell the difference between the two cases we test the flag
passed in for XATTR_REPLACE. The ll_getxattr function is
replaced by the generic_getxattr function.

1beba52d46 android: binder: Remove deprecated create_singlethread_workqueue
The workqueue is being used to run deferred work for the android binder.

The "binder_deferred_workqueue" queues only a single work item and hence
does not require ordering. Also, this workqueue is not being used on a
memory recliam path. Hence, the singlethreaded workqueue has been
replaced with the use of system_wq.

System workqueues have been able to handle high level of concurrency
for a long time now and hence it's not required to have a singlethreaded
workqueue just to gain concurrency. Unlike a dedicated per-cpu workqueue
created with create_singlethread_workqueue(), system_wq allows multiple
work items to overlap executions even on the same CPU; however, a
per-cpu workqueue doesn't have any CPU locality or global ordering
guarantee unless the target CPU is explicitly specified and thus the
increase of local concurrency shouldn't make any difference.

Pull thermal updates from Zhang Rui:

 - Fix a race condition when updating cooling device, which may lead to
   a situation where a thermal governor never updates the cooling
   device.  From Michele Di Giorgio.

 - Fix a zero division error when disabling the forced idle injection
   from the intel powerclamp.  From Petr Mladek.

 - Add suspend/resume callback for intel_pch_thermal thermal driver.
   From Srinivas Pandruvada.

 - Another two fixes for clocking cooling driver and hwmon sysfs I/F.
   From Michele Di Giorgio and Kuninori Morimoto.

[ Hmm.  That suspend/resume callback for intel_pch_thermal doesn't look
  like a fix, but I'm letting it slide..  - Linus ]
