Some system's ACPI video backlight control interface is broken and the
native backlight control interface should be used by default. This patch
sets the use_native_backlight parameter to true for those systems so
that video backlight control interface will not be created. For detailed
models that are added here, reference the following list.
Note that the user specified kernel cmdline option will always have the
highest priority, i.e. if use_native_backlight=0 is specified and the
system is in the DMI table, the video module will not skip registering
backlight interface for it.

Some devices have duplicate entries in there brightness levels table, ie
on my Dell Latitude E6430 the table looks like this:
[ 3.686060] acpi backlight index 0, val 80
[ 3.686095] acpi backlight index 1, val 50
[ 3.686122] acpi backlight index 2, val 5
[ 3.686147] acpi backlight index 3, val 5
[ 3.686172] acpi backlight index 4, val 5
[ 3.686197] acpi backlight index 5, val 5
[ 3.686223] acpi backlight index 6, val 5
[ 3.686248] acpi backlight index 7, val 5
[ 3.686273] acpi backlight index 8, val 6
[ 3.686332] acpi backlight index 9, val 7
[ 3.686356] acpi backlight index 10, val 8
[ 3.686380] acpi backlight index 11, val 9
etc.
Notice that brightness values 0-5 are all mapped to 5. This means that
if userspace writes any value between 0 and 5 to the brightness sysfs attribute
and then reads it, it will always return 0, which is somewhat unexpected.
This is a problem for ie gnome-settings-daemon, which uses read-modify-write
logic when the users presses the brightness up or down keys. This is done
this way to take brightness changes from other sources into account.
On this specific laptop what happens once the brightness has been set to 0,
is that gsd reads 0, adds 5, writes 5, and on the next brightness up key press
again reads 0, so things get stuck at the lowest brightness setting.
Filtering out the duplicate table entries, makes any write to brightness
read back as the written value as one would expect, fixing this.

In ed1f50c3a ("net: add skb_checksum_setup") we introduced some checksum
functions in core driver. Subsequent change b5cf66cd1 ("xen-netfront:
use new skb_checksum_setup function") made use of those functions to
replace its own implementation.
However with that change netfront is broken. It sees a lot of checksum
error. That's because its own implementation of checksum function was a
bit hacky (dereferencing skb->data directly) while the new function was
implemented using ip_hdr(). The network header is not reset before skb
is passed to the new function. When the new function tries to do its
job, it's confused and reports error.
The fix is simple, we need to reset network header before passing skb to
checksum function. Netback is not affected as it already does the right
thing.

If CLK_SET_RATE_PARENT is set for a clkoutx2 clock, calling
clk_set_rate() on the clock "skips" the x2 multiplier as there are no
set_rate and round_rate functions defined for the clkoutx2.
This results in getting double the requested clock rates, breaking the
display on omap3430 based devices. This got broken when
d0f58bd3bba3877fb1af4664c4e33273d36f00e4 and related patches were merged
for v3.14, as omapdss driver now relies more on the clk-framework and
CLK_SET_RATE_PARENT.
This patch implements set_rate and round_rate for clkoutx2.
Tested on OMAP3430, OMAP3630, OMAP4460.

The following patchset contains Netfilter fixes for your net tree,
they are:
* Fix nf_trace in nftables if XT_TRACE=n, from Florian Westphal.
* Don't use the fast payload operation in nf_tables if the length is
not power of 2 or it is not aligned, from Nikolay Aleksandrov.
* Fix missing break statement the inet flavour of nft_reject, which
results in evaluating IPv4 packets with the IPv6 evaluation routine,

* Fix wrong kconfig symbol in nft_meta to match the routing realm,
from Paul Bolle.
* Allocate the NAT null binding when creating new conntracks via
ctnetlink to avoid that several packets race at initializing the
the conntrack NAT extension, original patch from Florian Westphal,
revisited version from me.
* Fix DNAT handling in the snmp NAT helper, the same handling was being
done for SNAT and DNAT and 2.4 already contains that fix, from
Francois-Xavier Le Bail.

The generic sched_clock registration function was previously
done lockless, due to the fact that it was expected to be called
only once. However, now there are systems that may register
multiple sched_clock sources, for which the lack of locking has
casued problems:
If two sched_clock sources are registered we may end up in a
situation where a call to sched_clock() may be accessing the
epoch cycle count for the old counter and the cycle count for the
new counter. This can lead to confusing results where
sched_clock() values jump and then are reset to 0 (due to the way
the registration function forces the epoch_ns to be 0).
Fix this by reorganizing the registration function to hold the
seqlock for as short a time as possible while we update the
clock_data structure for a new counter. We also put any
accumulated time into epoch_ns instead of resetting the time to
0 so that the clock doesn't reset after each successful
registration.

Today, if
xfs_sb_read_verify
xfs_sb_verify
xfs_mount_validate_sb
detects superblock corruption, it'll be extremely noisy, dumping
2 stacks, 2 hexdumps, etc.
This is because we call XFS_CORRUPTION_ERROR in xfs_mount_validate_sb
as well as in xfs_sb_read_verify.
Also, *any* errors in xfs_mount_validate_sb which are not corruption
per se; things like too-big-blocksize, bad version, bad magic, v1 dirs,
rw-incompat etc - things which do not return EFSCORRUPTED - will
still do the whole XFS_CORRUPTION_ERROR spew when xfs_sb_read_verify
sees any error at all. And it suggests to the user that they
should run xfs_repair, even if the root cause of the mount failure
is a simple incompatibility.
I'll submit that the probably-not-corrupted errors don't warrant
this much noise, so this patch removes the warning for anything
other than EFSCORRUPTED returns, and replaces the lower-level
XFS_CORRUPTION_ERROR with an xfs_notice().

When xfs_readsb() does the very first read of the superblock,
it makes a guess at the length of the buffer, based on the
sector size of the underlying storage. This may or may
not match the filesystem sector size in sb_sectsize, so
we can't i.e. do a CRC check on it; it might be too short.
In fact, mounting a filesystem with sb_sectsize larger
than the device sector size will cause a mount failure
if CRCs are enabled, because we are checksumming a length
which exceeds the buffer passed to it.
So always read twice; the first time we read with NULL
buffer ops to skip verification; then set the proper
read length, hook up the proper verifier, and give it
another go.
Once we are sure that we've got the right buffer length,
we can also use bp->b_length in the xfs_sb_read_verify,
rather than the less-trusted on-disk sectorsize for
secondary superblocks. Before this we ran the risk of
passing junk to the crc32c routines, which didn't always
handle extreme values.

My earlier commit 10e6e65 deserves a layer or two of brown paper
bags. The logic in that commit means that a CRC failure on the
primary superblock will *never* result in an error return.
Hopefully this fixes it, so that we always return the error
if it's a primary superblock, otherwise only if the filesystem
has CRCs enabled.

Fix tegra_init_cache() to check whether the system has a PL310 cache
before touching the PL310 registers. This prevents access to non-existent
registers on Tegra114 and later.

The powernow-k8 driver maintains a per-cpu data-structure called
powernow_data that is used to perform the frequency transitions.
It initializes this data structure only for the policy->cpu. So,
accesses to this data structure by other CPUs results in various
problems because they would have been uninitialized.
Specifically, if a cpu (!= policy->cpu) invokes the drivers' ->get()
function, it returns 0 as the KHz value, since its per-cpu memory
doesn't point to anything valid. This causes problems during
suspend/resume since cpufreq_update_policy() tries to enforce this
(0 KHz) as the current frequency of the CPU, and this madness gets
propagated to adjust_jiffies() as well. Eventually, lots of things
start breaking down, including the r8169 ethernet card, in one
particularly interesting case reported by Pierre Ossman.
Fix this by initializing the per-cpu data-structures of all the CPUs
in the policy appropriately.

When building a kernel image with only CONFIG_CPU_IDLE but no CONFIG_PM,
we will get the following link error.
LD init/built-in.o

make[1]: *** [vmlinux] Error 1
Since pm-imx6q.c has been a collection of library functions that access
CCM low-power registers used by not only suspend but also cpuidle and
other drivers, let's build pm-imx6q.c independently of CONFIG_PM to fix
above error.

Pull ARM fixes from Russell King:
"A range of ARM fixes. Biggest change is the stage-2 attributes used
for for hyp mode which were wrong. I've killed some bits in a couple
of DT files which turned out not to be required, and a few other
fixes.
One fix touches code outside of arch/arm, which is related to sorting
out the DMA masks correctly. There is a long standing issue with the
conversion from PFNs to addresses where people assume that shifting an
unsigned long left by PAGE_SHIFT results in a correct address. This
is not the case with C: the integer promotion happens at assignment
after evaluation. This fixes the recently introduced dma_max_pfn()
function, but there's a number of other places where we try this
directly on an unsigned long in the mm code"
