Since initial support was provided for the Nomadik I2C driver, it
has been converted to an AMBA device. AMBA devices are probed in
a slightly different way to other devices, so we have to identify
them using an "arm,primecell" compatible string. As well as doing
just that, this patch specifies which regulators the controller
should use and requests a clock-speed. The latter is provided as
more of an example, as it's the same as the recently changed
default configuration.

There was a plan to place ab8500_irq_get_virq() calls in each AB8500

Device Tree to collect our IRQ numbers, it's actually better to allow
the core to do this during device registration time. So the IRQ number
we pull from its resource has already been converted to a virtual IRQ.

however, the AB8500 uses the GIC as it's interrupt controller. If

of_irq_find_parent is a handy function to use outside the confines of
the Open Firmware subsystem. One such use-case is when the IRQ Domain
wishes to find an IRQ domain for a given device node. Currently it can
not take any notice of the 'interrupt-parent' property. Instead it
just uses the first IRQ controller as it climbs the Device Tree. If
we were to use this as a precursor the resultant controller is more
likely to be correct.

This reverts commit 970e178985.
Nikolay Ulyanitsky reported thatthe 3.6-rc5 kernel has a 15-20%
performance drop on PostgreSQL 9.2 on his machine (running "pgbench").
Borislav Petkov was able to reproduce this, and bisected it to this
commit 970e178985 ("sched: Improve scalability via 'CPU buddies' ...")
apparently because the new single-idle-buddy model simply doesn't find
idle CPU's to reschedule on aggressively enough.
Mike Galbraith suspects that it is likely due to the user-mode spinlocks
in PostgreSQL not reacting well to preemption, but we don't really know
the details - I'll just revert the commit for now.
There are hopefully other approaches to improve scheduler scalability
without it causing these kinds of downsides.

Currently the MFD core supports remapping MFD cell interrupts using an
irqdomain but only if the MFD is being instantiated using device tree
and only if the device tree bindings use the pattern of registering IPs
in the device tree with compatible properties. This will be actively
harmful for drivers which support non-DT platforms and use this pattern
for their DT bindings as it will mean that the core will silently change
remapping behaviour and it is also limiting for drivers which don't do
DT with this particular pattern. There is also a potential fragility if
there are interrupts not associated with MFD cells and all the cells are
omitted from the device tree for some reason.
Instead change the code to take an IRQ domain as an optional argument,
allowing drivers to take the decision about the parent domain for their
interrupts. The one current user of this feature is ab8500-core, it has
the domain lookup pushed out into the driver.

A bigger set of updates than I'm entirely comfortable with - things
backed up a bit due to travel. As ever the majority of these are small,
focused updates for specific drivers though there are a couple of core
changes. There's been good exposure in -next.
The AT91 patch fixes a build break.

ASoC: Updates for 3.6
A bigger set of updates than I'm entirely comfortable with - things
backed up a bit due to travel. As ever the majority of these are small,
focused updates for specific drivers though there are a couple of core
changes. There's been good exposure in -next.
The AT91 patch fixes a build break.
Pull GFS2 fixes from Steven Whitehouse:
"Here are three GFS2 fixes for the current kernel tree. These are all
related to the block reservation code which was added at the merge
window. That code will be getting an update at the forthcoming merge
window too. In the mean time though there are a few smaller issues
which should be fixed.
The first patch resolves an issue with write sizes of greater than 32
bits with the size hinting code. The second ensures that the
allocation data structure is initialised when using xattrs and the
third takes into account allocations which may have been made by other
nodes which affect a reservation on the local node."
* git://git.kernel.org/pub/scm/linux/kernel/git/steve/gfs2-3.0-fixes:
GFS2: Take account of blockages when using reserved blocks
GFS2: Fix missing allocation data for set/remove xattr
GFS2: Make write size hinting code common
Pull x86 platform driver updates from Matthew Garrett:
"A few small updates for 3.6 - a trivial regression fix and a couple of
conformance updates for the gmux driver, plus some tiny fixes for
asus-wmi, eeepc-laptop and thinkpad_acpi."
* 'for_linus' of git://cavan.codon.org.uk/platform-drivers-x86:
thinkpad_acpi: buffer overflow in fan_get_status()
eeepc-laptop: fix device reference count leakage in eeepc_rfkill_hotplug()
platform/x86: fix asus_laptop.wled_type description
asus-laptop: HRWS/HWRS typo
drivers-platform-x86: remove useless #ifdef CONFIG_ACPI_VIDEO
apple-gmux: Fix port address calculation in gmux_pio_write32()
apple-gmux: Fix index read functions
apple-gmux: Obtain version info from indexed gmux
Pull i2c embedded fixes from Wolfram Sang:
"The last bunch of (typical) i2c-embedded driver fixes for 3.6.
Also update the MAINTAINERS file to point to my tree since people keep
asking where to find their patches."
* 'i2c-embedded/for-current' of git://git.pengutronix.de/git/wsa/linux:
i2c: algo: pca: Fix mode selection for PCA9665
MAINTAINERS: fix tree for current i2c-embedded development
i2c: mxs: correctly setup speed for non devicetree
i2c: pnx: Fix read transactions of >= 2 bytes
i2c: pnx: Fix bit definitions
shared memory mapping is dirtied and unmapped. The lower file was being
released when the eCryptfs file was closed and the dirtied pages could not be
written out.
- Adds a call to the lower filesystem's ->flush() from ecryptfs_flush().
- Fixes a regression, introduced in 2.6.39, when a file is renamed on top of
another file. The target file's inode was not being evicted and the space
taken by the file was not reclaimed until eCryptfs was unmounted.

Merge tag 'ecryptfs-3.6-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs
Pull ecryptfs fixes from Tyler Hicks:
- Fixes a regression, introduced in 3.6-rc1, when a file is closed
before its shared memory mapping is dirtied and unmapped. The lower
file was being released when the eCryptfs file was closed and the
dirtied pages could not be written out.
- Adds a call to the lower filesystem's ->flush() from
ecryptfs_flush().
- Fixes a regression, introduced in 2.6.39, when a file is renamed on
top of another file. The target file's inode was not being evicted
and the space taken by the file was not reclaimed until eCryptfs was
unmounted.
* tag 'ecryptfs-3.6-rc6-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs:
eCryptfs: Copy up attributes of the lower target inode after rename
eCryptfs: Call lower ->flush() from ecryptfs_flush()
eCryptfs: Write out all dirty pages just before releasing the lower file
Pull one more DMA-mapping fix from Marek Szyprowski:
"This patch fixes very subtle bug (typical off-by-one error) which
might appear in very rare circumstances."
* 'fixes-for-3.6' of git://git.linaro.org/people/mszyprowski/linux-dma-mapping:
