Besides some fixes and cleanups in the code there are three more
important changes to point out this time:
* New IOMMU driver for the ARM SHMOBILE platform
* An IOMMU-API extension for non-paging IOMMUs (required for
upcoming PAMU driver)
* Rework of the way the Tegra IOMMU driver accesses its
registetrs - register windows are easier to extend now.
There are also a few changes to non-iommu code, but that is acked by the
respective maintainers.

A new driver has been added to support the PWM mode of the timer counter
blocks found on Atmel AT91 SoCs. The VT8500 driver now supports changing
the PWM signal polarity and the TI drivers (EHRPWM and ECAP) gained
suspend and resume functionality.
User drivers can now query the core for whether access to a PWM device
will sleep (if the PWM chip is on a slow bus such as I2C or SPI).
The pwm-backlight driver now handles the backlight BL_CORE_FBBLANK state
in addition to the FB layer's blanking states.
To round things off, a few fixes and cleanups are also included.

Pull user namespace and namespace infrastructure changes from Eric W Biederman:
"This set of changes starts with a few small enhnacements to the user
namespace. reboot support, allowing more arbitrary mappings, and
support for mounting devpts, ramfs, tmpfs, and mqueuefs as just the
user namespace root.
I do my best to document that if you care about limiting your
unprivileged users that when you have the user namespace support
enabled you will need to enable memory control groups.
There is a minor bug fix to prevent overflowing the stack if someone
creates way too many user namespaces.
The bulk of the changes are a continuation of the kuid/kgid push down
work through the filesystems. These changes make using uids and gids
typesafe which ensures that these filesystems are safe to use when
multiple user namespaces are in use. The filesystems converted for
3.9 are ceph, 9p, afs, ocfs2, gfs2, ncpfs, nfs, nfsd, and cifs. The
changes for these filesystems were a little more involved so I split
the changes into smaller hopefully obviously correct changes.
XFS is the only filesystem that remains. I was hoping I could get
that in this release so that user namespace support would be enabled
with an allyesconfig or an allmodconfig but it looks like the xfs
changes need another couple of days before it they are ready."

No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data consolidation,
OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee Jones. In
particular, the debugfs and the sysct interfaces got extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the twl-core
driver, with a much needed module id lookup code improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the palmas
GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra and
Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and ab9540 based
devices to switch to the new abx500 pin-ctrl driver.
- The max8925 now has device tree and irqdomain support thanks to Qing Xu.
- The recently added rtsx driver got a few cleanups and fixes for a better
card detection code path and now also supports the RTS5227 chipset, thanks
to Wei Wang and Roger Tseng.

Merge tag 'mfd-3.9-1' of git://git.kernel.org/pub/scm/linux/kernel/git/sameo/mfd-2.6
Pull MFS updates from Samuel Ortiz:
"This is the MFD pull request for the 3.9 merge window.
No new drivers this time, but a bunch of fairly big cleanups:
- Roger Quadros worked on a OMAP USBHS and TLL platform data
consolidation, OMAP5 support and clock management code cleanup.
- The first step of a major sync for the ab8500 driver from Lee
Jones. In particular, the debugfs and the sysct interfaces got
extended and improved.
- Peter Ujfalusi sent a nice patchset for cleaning and fixing the
twl-core driver, with a much needed module id lookup code
improvement.
- The regular wm5102 and arizona cleanups and fixes from Mark Brown.
- Laxman Dewangan extended the palmas APIs in order to implement the
palmas GPIO and rt drivers.
- Laxman also added DT support for the tps65090 driver.
- The Intel SCH and ICH drivers got a couple fixes from Aaron Sierra
and Darren Hart.
- Linus Walleij patchset for the ab8500 driver allowed ab8500 and
ab9540 based devices to switch to the new abx500 pin-ctrl driver.
- The max8925 now has device tree and irqdomain support thanks to
Qing Xu.
- The recently added rtsx driver got a few cleanups and fixes for a
better card detection code path and now also supports the RTS5227
chipset, thanks to Wei Wang and Roger Tseng."

Commit 81732c3b2f ("tty vt: Fix line garbage in virtual console on
command line edition") broke insert_char() in multiple ways. Then
commit b1a925f44a ("tty vt: Fix a regression in command line edition")
partially fixed it. However, the buffer being moved is still too large
and overflowing beyond the end of the current line, corrupting existing
characters on the next line.
Example test case:
echo -e "abc\nde\x1b[A\x1b[4h \x1b[4l\x1b[B"
Expected result:
ab c
de
Current result:
ab c
e
Needless to say that this is very annoying when inserting words in the
middle of paragraphs with certain text editors.

Merge tag 'stable/for-linus-3.9-rc0-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/konrad/xen
Pull Xen update from Konrad Rzeszutek Wilk:
"This has two new ACPI drivers for Xen - a physical CPU offline/online
and a memory hotplug. The way this works is that ACPI kicks the
drivers and they make the appropiate hypercall to the hypervisor to
tell it that there is a new CPU or memory. There also some changes to
the Xen ARM ABIs and couple of fixes. One particularly nasty bug in
the Xen PV spinlock code was fixed by Stefan Bader - and has been
there since the 2.6.32!
Features:
- Xen ACPI memory and CPU hotplug drivers - allowing Xen hypervisor
to be aware of new CPU and new DIMMs
- Cleanups
Bug-fixes:
- Fixes a long-standing bug in the PV spinlock wherein we did not
kick VCPUs that were in a tight loop.
- Fixes in the error paths for the event channel machinery"
Fix up a few semantic conflicts with the ACPI interface changes in
drivers/xen/xen-acpi-{cpu,mem}hotplug.c.

Tegra only supports, and always enables, device tree. Remove all ifdefs
and runtime checks for DT support from the driver. Platform data is
therefore no longer required. Rework the driver to parse the device tree
directly into struct sdhci_tegra.

Many MMC capability flags are platform-dependent and are traditionally set
in platform data. With DT often each such capability requires a special
binding. Add bindings for MMC_CAP_SD_HIGHSPEED, MMC_CAP_MMC_HIGHSPEED,
MMC_CAP_POWER_OFF_CARD and MMC_CAP_SDIO_IRQ capabilities. Also add code to
DT parser to look up "keep-power-in-suspend" and "enable-sdio-wakeup"
bindings and set MMC_PM_KEEP_POWER and MMC_PM_WAKE_SDIO_IRQ respectively,
if found.

Some SD/MMC interfaces use 2 power regulators: one to power the card itself
(Vcc) and another one to pull signal lines up (VccQ). In case of eMMC and
UHS SD cards the regulators also have to be configured to supply different
voltages. The preferred order of turning supply power on and off is to
turn Vcc first on and last off.
