The clock driver now supports a muxable ahb clock. Update the dtsi
with the proper compatible and add the new parent clocks.
This also adds the new pll6/4 output for pll6 on sun7i-a20. The
output is not used on sun4/5i.
Also use assigned-clocks to reparent ahb to pll6. We want ahb to
have a stable, non-changing clock rate. cpu/axi clock rate changes

x86_64, asm: Work around AMD SYSRET SS descriptor attribute issue
AMD CPUs don't reinitialize the SS descriptor on SYSRET, so SYSRET with
SS == 0 results in an invalid usermode state in which SS is apparently
equal to __USER_DS but causes #SS if used.
Work around the issue by setting SS to __KERNEL_DS __switch_to, thus
ensuring that SYSRET never happens with SS set to NULL.
This was exposed by a recent vDSO cleanup.

"This lays a little of the groundwork for upcoming Shared Virtual
Memory support — fixing some bogus #defines for capability bits and
adding the new ones, and starting to use the new wider page tables
where we can, in anticipation of actually filling in the new fields
therein.
It also allows graphics devices to be assigned to VM guests again.
This got broken in 3.17 by disallowing assignment of RMRR-afflicted
devices. Like USB, we do understand why there's an RMRR for graphics
devices — and unlike USB, it's actually sane. So we can make an
exception for graphics devices, just as we do USB controllers.
Finally, tone down the warning about the X2APIC_OPT_OUT bit, due to
persistent requests. X2APIC_OPT_OUT was added to the spec as a nasty
hack to allow broken BIOSes to forbid us from using X2APIC when they
do stupid and invasive things and would break if we did.
Someone noticed that since Windows doesn't have full IOMMU support for
DMA protection, setting the X2APIC_OPT_OUT bit made Windows avoid
initialising the IOMMU on the graphics unit altogether.
This means that it would be available for use in "driver mode", where
the IOMMU registers are made available through a BAR of the graphics
device and the graphics driver can do SVM all for itself.
So they started setting the X2APIC_OPT_OUT bit on *all* platforms with
SVM capabilities. And even the platforms which *might*, if the
planets had been aligned correctly, possibly have had SVM capability
but which in practice actually don't"

- Changes in the way that the atmel_mxt trackpads are probed. The
laptop driver is trying to be smart and not instantiate the devices
that don't answer to probe. For the trackpad that can come up in
two modes (bootloader or regular), this gets complicated since the
driver already knows how to handle the two modes including the
actual addresses used. So now the laptop driver needs to know more
too, instantiating the regular address even if the bootloader one
is the probe that passed.

platform/chrome: chromeos_laptop - instantiate Atmel at primary address
The new Atmel MXT driver expects i2c client's address contain the
primary (main address) of the chip, and calculates the expected
bootloader address form the primary address. Unfortunately chrome_laptop
does probe the devices and if touchpad (or touchscreen, or both) comes
up in bootloader mode the i2c device gets instantiated with the
bootloader address which confuses the driver.
To work around this issue let's probe the primary address first. If the
device is not detected at the primary address we'll probe alternative
addresses as "dummy" devices. If any of them are found, destroy the
dummy client and instantiate client with proper name at primary address
still.

RCU pathwalk breakage when running into a symlink overmounting something
Calling unlazy_walk() in walk_component() and do_last() when we find
a symlink that needs to be followed doesn't acquire a reference to vfsmount.
That's fine when the symlink is on the same vfsmount as the parent directory
(which is almost always the case), but it's not always true - one _can_
manage to bind a symlink on top of something. And in such cases we end up
with excessive mntput().

direct-io: only inc/dec inode->i_dio_count for file systems
do_blockdev_direct_IO() increments and decrements the inode
->i_dio_count for each IO operation. It does this to protect against
truncate of a file. Block devices don't need this sort of protection.
For a capable multiqueue setup, this atomic int is the only shared
state between applications accessing the device for O_DIRECT, and it
presents a scaling wall for that. In my testing, as much as 30% of
system time is spent incrementing and decrementing this value. A mixed
read/write workload improved from ~2.5M IOPS to ~9.6M IOPS, with
better latencies too. Before:
clat percentiles (usec):
| 1.00th=[ 33], 5.00th=[ 34], 10.00th=[ 34], 20.00th=[ 34],

In other setups, Robert Elliott reported seeing good performance
improvements:
https://lkml.org/lkml/2015/4/3/557
The more applications accessing the device, the worse it gets.
Add a new direct-io flags, DIO_SKIP_DIO_COUNT, which tells
do_blockdev_direct_IO() that it need not worry about incrementing
or decrementing the inode i_dio_count for this caller.

Btrfs: prevent list corruption during free space cache processing
__btrfs_write_out_cache is holding the ctl->tree_lock while it prepares
a list of bitmaps to record in the free space cache. It was dropping
the lock while it worked on other components, which made a window for
free_bitmap() to free the bitmap struct without removing it from the
list.
This changes things to hold the lock the whole time, and also makes sure
we hold the lock during enospc cleanup.
