8024206dbf ARM: tegra: cleanup
This branch includes various cleanup of the core Tegra support.
 
 * Unification of the separate board-dt-tegra*.c files into a single
   tegra.c, now that everything is DT-driven and basically identical.
 * Use of_clk_get() in the Tegra clocksource driver so that clocks are
   described in DT rather than hard-coding clock names.
 * Some cleanup of the PMC-related code, with the aim that the PMC
   "driver" contains more of the code that touches PMC registers, rather
   than spreading PMC register accesses through other files.
 * Conversion of the "PMC" driver to acquire resources describe in device
   tree rather than hard-coding them.
 * Use of common code for the CPU sleep TLB invalidation.
 
 This branch is based on the previous fixes pull request.

5c1ff33640 ext4: fix free space estimate in ext4_nonda_switch()
Values stored in s_freeclusters_counter and s_dirtyclusters_counter
are both in cluster units.  Remove the cluster to block conversion
applied to s_freeclusters_counter causing an inflated estimate of
free space because s_dirtyclusters_counter is not similarly
converted.  Rename free_blocks and dirty_blocks to better reflect
the units these variables contain to avoid future confusion.  This
fix corrects ENOSPC failures for xfstests 127 and 231 on bigalloc
file systems.

bcb1385096 ext4: fix deadlock with quota feature
We didn't mark hidden quota files with S_NOQUOTA flag and thus quota was

Merge tag 'tegra-for-3.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra into next/fixes-non-critical

From Stephen Warren <swarren@wwwdotorg.org>:

ARM: tegra: minor fixes

This branch contains a variety of small build and run-time fixes that
weren't important enough for 3.9.

* Enable CPU errata WARs in secondary reset handler as a preparation
  for multi-platform support, and a related fix.
* Don't touch DBLGAR in reset/resume handlers, so enable the code to
  run on A15 cores.
* Minor build fixes.
* A fix to the Tegra clock driver.
* Some error-handling fixes.

This branch is based on the previous fixes-for-mmc pull request.

* tag 'tegra-for-3.10-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/swarren/linux-tegra:
  ARM: tegra: powergate: Don't error out if new state == old state
  ARM: tegra: Export tegra_powergate_sequence_power_up()
  memory: tegra30: Fix build error w/o PM
  ARM: tegra: fix ignored return value of regulator_enable
  ARM: tegra: fix the logical detection of power on sequence of warm boot CPUs
  ARM: tegra: Fix unchecked return value
  ARM: tegra: don't unlock MMIO access to DBGLAR
  clk: tegra: No 7.1 super clk dividers on Tegra20
  ARM: tegra: remove save/restore of CPU diag register
  ARM: tegra: add CPU errata WARs to Tegra reset handler
  ARM: dts: tegra: fix the activate polarity of cd-gpio in mmc host

0c7c3e67ab nfsd4: don't close read-write opens too soon
Don't actually close any opens until we don't need them at all.

This means being left with write access when it's not really necessary,
but that's better than putting a file that might still have posix locks
held on it, as we have been.

eb2099f31b nfsd4: release lockowners on last unlock in 4.1 case
In the 4.1 case we're supposed to release lockowners as soon as they're
no longer used.

It would probably be more efficient to reference count them, but that's
slightly fiddly due to the need to have callbacks from locks.c to take
into account lock merging and splitting.

For most cases just scanning the inode's lock list on unlock for
matching locks will be sufficient.

e5072664f8 blkcg: fix "scheduling while atomic" in blk_queue_bypass_start
Since 749fefe677 in v3.7 ("block: lift the initial queue bypass mode
on blk_register_queue() instead of blk_init_allocated_queue()"),
the following warning appears when multipath is used with CONFIG_PREEMPT=y.

This patch moves blk_queue_bypass_start() before radix_tree_preload()
to avoid the sleeping call while preemption is disabled.

0a01216c45 The imx fixes for 3.9, take 5:
* A couple imx35 clock fixes for regressions caused by common clock
   framework conversion.  The admux and iomux get disabled by common
   clock framework late initcall, and hence causes problems.
 * Add missing twd clock lookup in device tree.  This becomes required
   since commit bd60345 (ARM: use device tree to get smp_twd clock)
   forces all DT boot to find lookup from device tree.
 * Fix imx6q ldb_di clock parents mismatch per reference manual.

13ab6aeb49 ARM: at91: change "Unknown" qualifier SoC subtype handling
An AT91 SoC that doesn't have a subtype is shown as "Unknown"
in the Linux log message which is not correct.
This was leading to confusion so, add a "none" qualifier to
the subtype property and set this one in the appropriate cases.

fbf8e13d31 ARC: [kbuild] Allow platforms to disable LLSC for !SMP as well
Currently ARC_HAS_LLSC can be influenced by platform for SMP only using
ARC_HAS_COH_LLSC. For !SMP it defaults to "y".

It turns out that some customers can't support it all, even in UP.
So we change the semantics, and use a negative dependency ARC_CANT_LLSC.
Any platform (independent of SMP or !SMP) can select it to disable LLSC.

2bb4b70b1d ARM: imx: provide twd clock lookup from device tree
While booting from device tree, imx6q used to provide twd clock lookup
by calling clk_register_clkdev() in clock driver.  However, the commit
bd60345 (ARM: use device tree to get smp_twd clock) forces DT boot to
look up the clock from device tree.  It causes the failure below when
twd driver tries to get the clock, and hence kernel has to calibrate the
local timer frequency.

 smp_twd: clock not found -2
 ...
 Calibrating local timer... 396.13MHz.

Fix the regression by providing twd clock lookup from device tree, and
remove the unused twd clk_register_clkdev() call from clock driver.

cab1e0a36c ARM: clk-imx35: Bugfix iomux clock
This patch enables iomuxc_gate clock. It is necessary to be able to
reconfigure iomux pads. Without this clock enabled, the
clk_disable_unused function will disable this clock and the iomux pads
are not configurable anymore. This happens at every boot. After a reboot
(watchdog system reset) the clock is not enabled again, so all iomux pad
reconfigurations in boot code are without effect.

The iomux pads should be always configurable, so this patch always
enables it.
