3e9a97082f This patch series contains a major revamp of how we collect entropy
from interrupts for /dev/random and /dev/urandom.  The goal is to
 addresses weaknesses discussed in the paper "Mining your Ps and Qs:
 Detection of Widespread Weak Keys in Network Devices", by Nadia
 Heninger, Zakir Durumeric, Eric Wustrow, J. Alex Halderman, which will
 be published in the Proceedings of the 21st Usenix Security Symposium,
 August 2012.  (See https://factorable.net for more information and an
 extended version of the paper.)

27c1ee3f92 Merge branch 'akpm' (Andrew's patch-bomb)
Merge Andrew's first set of patches:
 "Non-MM patches:

   - lots of misc bits

   - tree-wide have_clk() cleanups

   - quite a lot of printk tweaks.  I draw your attention to "printk:
     convert the format for KERN_<LEVEL> to a 2 byte pattern" which
     looks a bit scary.  But afaict it's solid.

   - backlight updates

   - lib/ feature work (notably the addition and use of memweight())

   - checkpatch updates

   - rtc updates

   - nilfs updates

   - fatfs updates (partial, still waiting for acks)

c1d7e01d78 ipc: use Kconfig options for __ARCH_WANT_[COMPAT_]IPC_PARSE_VERSION
Rather than #define the options manually in the architecture code, add
Kconfig options for them and select them there instead.  This also allows
us to select the compat IPC version parsing automatically for platforms
using the old compat IPC interface.

7041717e7c arch/arm/mach-netx/fb.c: reuse dummy clk routines for CONFIG_HAVE_CLK=n
mach-netx had its own implementation of clk routines like, clk_get{put},
clk_enable{disable}, etc.  And with introduction of following patchset:

  https://lkml.org/lkml/2012/4/24/154

we get compilation error for multiple definition of these routines.

Sascha had following suggestion to deal with it:

  http://www.spinics.net/lists/arm-kernel/msg179369.html

So, remove this code completely.

We have support for a few new drivers:
 - Samsung s2mps11
 - Wolfson Microelectronics wm5102 and wm5110
 - Marvell 88PM800 and 88PM805
 - TI twl6041
 
 We also have our regular driver improvements:

Fix up mostly trivial conflicts, with the exception of
drivers/usb/host/ehci-omap.c in particular, which had some
re-organization of the reset sequence (commit 1a49e2ac96: "EHCI:
centralize controller initialization") that clashed with commit
2761a63945 ("mfd: USB: Fix the omap-usb EHCI ULPI PHY reset fix
issues").

In particular, commit 2761a63945 moved the usb_add_hcd() to the
*middle* of the reset sequence, which clashes fairly badly with the
reset sequence re-organization (although it could have been done inside
the new omap_ehci_init() function).

I left that part of commit 2761a63945 just undone.

  of additional kernel mapping for some specific use cases) as well as

9ec97169e7 Merge branch 'for-3.6' of git://gitorious.org/linux-pwm/linux-pwm
Pull PWM subsystem from Thierry Reding:
 "The new PWM subsystem aims at collecting all implementations of the
  legacy PWM API and to eventually replace it completely.

  The subsystem has been in development for over half a year now and
  many drivers have already been converted.  It has been in linux-next
  for a couple of weeks and there have been no major issues so I think
  it is ready for inclusion in your tree."

Arnd Bergmann <arnd@arndb.de>:
 "Very much Ack on the new subsystem.  It uses the interface
  declarations as the previously separate pwm drivers, so nothing
  changes for now in the drivers using it, although it enables us to
  change those more easily in the future if we want to.

  This work is also one of the missing pieces that are required to
  eventually build ARM kernels for multiple platforms, which is
  currently prohibited (amongs other things) by the fact that you cannot
  have more than one driver exporting the pwm functions."

97ef952a20 ARM: dma-mapping: add support for DMA_ATTR_SKIP_CPU_SYNC attribute
This patch adds support for DMA_ATTR_SKIP_CPU_SYNC attribute for
dma_(un)map_(single,page,sg) functions family. It lets dma mapping clients
to create a mapping for the buffer for the given device without performing
a CPU cache synchronization. CPU cache synchronization can be skipped for
the buffers which it is known that they are already in 'device' domain (CPU
caches have been already synchronized or there are only coherent mappings
for the buffer). For advanced users only, please use it with care.

64ccc9c033 common: dma-mapping: add support for generic dma_mmap_* calls
Commit 9adc5374 ('common: dma-mapping: introduce mmap method') added a
generic method for implementing mmap user call to dma_map_ops structure.

This patch converts ARM and PowerPC architectures (the only providers of
dma_mmap_coherent/dma_mmap_writecombine calls) to use this generic
dma_map_ops based call and adds a generic cross architecture
definition for dma_mmap_attrs, dma_mmap_coherent, dma_mmap_writecombine
functions.

The generic mmap virt_to_page-based fallback implementation is provided for
architectures which don't provide their own implementation for mmap method.

9fc377799b USB patches for 3.6-rc1
Here's the big USB patch set for the 3.6-rc1 merge window.
 
 Lots of little changes in here, primarily for gadget controllers and drivers.
 There's some scsi changes that I think also went in through the scsi tree, but
 they merge just fine.  All of these patches have been in the linux-next tree
 for a while now.

01ad8063a5 ARM: dt: tegra trimslice: add vbus-gpio property
On TrimSlice, Tegra's USB1 port may be routed to either an external micro
USB port, or an internal USB->SATA bridge for SSD or HDD. This muxing is
controlled by a GPIO. Whilst not strictly a VBUS GPIO, the TrimSlice
board files caused this GPIO to be set appropriately to enable the SATA
bridge by passing it as the VBUS GPIO to the USB driver. Echo this same
configuration in device tree to enable the SATA bridge.

An alternative might be to implement a full USB bus mux driver. However,
that seems over-complex right now.

b5409430ff ARM: Kirkwood: Fix PHY disable clk problems
Commit 98d9986 (ARM: Kirkwood: Replace clock gating) and the fix 5fb2ce
(ARM: Kirkwood: clk_register_gate_fn: add fn assignment) introduced a custom
variant of clock gating which allows to define a function to be called
before gating the clock off.

This is used to disable the SATA and PCIe PHYs if the respective clocks
are unused after initialization.

However, of these two drivers, the SATA driver may be compiled as a module.
The driver re-enables the clocks at module init but the PHYs stay disabled.

Since the custom clock gating disabled the PHYs when gating the clock off,
it should also re-enable them when enabling the clock gate.  This is done by
adding a second function that may be used to enable the PHYs.

f479db44d2 ARM: Kirkwood: Ensure runit clock always ticks.
Marvell engineers tell us:

	It seems that many units use the RUNIT clock.
	SPI, UART, NAND, TWSI, ...
	So it's not possible to clock gate it.

Currently the SPI, NAND and TWSI driver will clk_prepaure_enable()
this clk, but since we have no idea what ... is, and turning this clk
off results in a hard lock, unconditionally enable runit.

3d55c29fb2 ARM: tegra: harmony: add regulator supply name and its input supply
Name the regulator as per board schematics and adds its
supply name info in regulator data.
Add the always on fixed regulator to refer the battery supply.

Use this fixed regulator for input supply of some of PMIC
regulator

This patch was originally part of a 2-patch series. Patch 2 got applied
to the regulator tree as 7c7fac3 "regulator: tps6586x: add support for
input supply" without this patch. This broke regulator support on
Harmony.

97e7292ab5 arm-soc: clk changes
Clock support is moving to the clk subsystem. These tegra, omap and imx
 changes are for code that is still platform specific and not (yet)
 part of that subsystem.
