Mel Gorman ed4a6d7f06 mm: compaction: add /sys trigger for per-node memory compaction
Add a per-node sysfs file called compact.  When the file is written to,
each zone in that node is compacted.  The intention that this would be
used by something like a job scheduler in a batch system before a job
starts so that the job can allocate the maximum number of hugepages
without significant start-up cost.

Linus Torvalds a69eee4988 Revert "ath9k: Group Key fix for VAPs"
This reverts commit 03ceedea97, since it
breaks resume from suspend-to-ram on Rafael's Acer Ferrari One.
NetworkManager thinks everything is ok, but it can't connect to the AP
to get an IP address after the resume.

In fact, it even breaks resume for non-ath9k chipsets: reverting it also
fixes Rafael's Toshiba Protege R500 with the iwlagn driver.  As Johannes
says:

  "Indeed, this patch needs to be reverted. That mac80211 change is wrong
   and completely unnecessary."

Grant Likely 44504b2beb of: change of_match_device to work with struct device
The of_node pointer is now stored directly in struct device, so
of_match_device() should work with any device, not just struct of_device.

This patch changes the interface to of_match_device() to accept a
struct device instead of struct of_device.

Grant Likely 4018294b53 of: Remove duplicate fields from of_platform_driver
.name, .match_table and .owner are duplicated in both of_platform_driver
and device_driver.  This patch is a removes the extra copies from struct
of_platform_driver and converts all users to the device_driver members.

This patch is a pretty mechanical change.  The usage model doesn't change
and if any drivers have been missed, or if anything has been fixed up
incorrectly, then it will fail with a compile time error, and the fixup
will be trivial.  This patch looks big and scary because it touches so
many files, but it should be pretty safe.

Christoph Hellwig 8018ab0574 sanitize vfs_fsync calling conventions
Now that the last user passing a NULL file pointer is gone we can remove
the redundant dentry argument and associated hacks inside vfs_fsynmc_range.

The next step will be removig the dentry argument from ->fsync, but given
the luck with the last round of method prototype changes I'd rather
defer this until after the main merge window.

Praveen Kalamegham ac81860ea0 PCI: hotplug: pciehp: Removed check for hotplug of display devices
Removed check to prevent hotplug of display devices within pciehp.
Originally this was thought to have been required within the PCI
Hotplug specification for some legacy devices.  However there is
no such requirement in the most recent revision. The check prevents
hotplug of not only display devices but also computational GPUs
which require serviceability.

Felix Radensky 3322340a9d PCI: Allow manual resource allocation for PCI hotplug bridges
At the moment only PCI-E briges can be flagged as hotplug, thus
allowing manual resource preallocation via pci=hpmemsize=nnM and
pci=hpiosize=nnM kernel parameters. Some PCI hotplug bridges, e.g.
PLX 6254 can also benefit from this functionalily, as kernel fails
to properly allocate their resources when hotplug device is added
and PCI bus is rescanned.

This patch adds header quirk for PLX 6254 that marks this bridge
as hotplug. Other PCI bridges with similar problems can use it
as well.

Arnaud Patard 3804a89bfb RTC: rtc-cmos: Fix binary mode support
As a follow-up to the thread about RTC support for some Loongson 2E/2F
boards, this patch tries to address the "REVISIT"/"FIXME" comments about
rtc binary mode handling and allow rtc to work with rtc in binary mode.
I've also raised the message about 24-h mode not supported to warning
otherwise, one may end up with no rtc without any message in the kernel
log.
