cc9a672ee5 tcp: allow tcp_sacktag_one() to tag ranges not aligned with skbs
This commit allows callers of tcp_sacktag_one() to pass in sequence
ranges that do not align with skb boundaries, as tcp_shifted_skb()
needs to do in an upcoming fix in this patch series.

In fact, now tcp_sacktag_one() does not need to depend on an input skb
at all, which makes its semantics and dependencies more clear.

ba8c4dc998 mmc: esdhc: fix errors when booting kernel on Freescale eSDHC version 2.3
When eSDHC module is enabled on P5020/P3041/P2041/P1010 with eSDHC
version 2.3, there is following errors:

mmc0: Timeout waiting for hardware interrupt.
mmc0: error -110 whilst initialising SD card
mmc0: Unexpected interrupt 0x02000000.
mmc0: Timeout waiting for hardware interrupt.
mmc0: error -110 whilst initialising SD card
mmc0: Unexpected interrupt 0x02000000.

It is because eSDHC controller has different bit setting for PROCTL
register at 0x28 comparing SD specification.
This patch sets DMAS bits correctly for byte operation and does not
change the default value of other field of PROCTL register.

For other FSL chips, such as MPC8536/P2020, PROCTL[DMAS]
bits are reserved and even if they are set to wrong bits, it will not
take effective.

5f2f389040 ASoC: wm_hubs: Improve single ended line output enable performance
The enable of the single ended line outputs on wm_hubs devices performs
better if the output is enabled prior to starting VMID. Since inactive
outputs are held at VMID anyway there is little cost to doing this for
unused outputs. Add callbacks into wm_hubs and keep track of which outputs
are really active so we can disable them once we're active.

Says Jens:

 "Time to push off some of the pending items.  I really wanted to wait
  until we had the regression nailed, but alas it's not quite there yet.
  But I'm very confident that it's "just" a missing expire on exit, so
  fix from Tejun should be fairly trivial.  I'm headed out for a week on
  the slopes.

  - Killing the barrier part of mtip32xx.  It doesn't really support
    barriers, and it doesn't need them (writes are fully ordered).

  - A few fixes from Dan Carpenter, preventing overflows of integer
    multiplication.

  - A fixup for loop, fixing a previous commit that didn't quite solve
    the partial read problem from Dave Young.

  - A bio integer overflow fix from Kent Overstreet.

  - Improvement/fix of the door "keep locked" part of the cdrom shared
    code from Paolo Benzini.

  - A few cfq fixes from Shaohua Li.

  - A fix for bsg sysfs warning when removing a file it did not create
    from Stanislaw Gruszka.

  - Two fixes for floppy from Vivek, preventing a crash.

  - A few block core fixes from Tejun.  One killing the over-optimized
    ioc exit path, cleaning that up nicely.  Two others fixing an oops
    on elevator switch, due to calling into the scheduler merge check
    code without holding the queue lock."

Tejun Heo
d8c66c5d59 block: fix lockdep warning on io_context release put_io_context()
11a3122f6c "block: strip out locking optimization in put_io_context()"
removed ioc_lock depth lockdep annoation along with locking
optimization; however, while recursing from put_io_context() is no
longer possible, ioc_release_fn() may still end up putting the last
reference of another ioc through elevator, which wlil grab ioc->lock
triggering spurious (as the ioc is always different one) A-A deadlock
warning.

As this can only happen one time from ioc_release_fn(), using non-zero
subclass from ioc_release_fn() is enough.  Use subclass 1.

3) Off by ones and other bug fixes in netprio_cgroup from Neil Horman.

4) ipv4 TCP reset generation needs to respect any network interface

6) Fix SKB under-allocation bug in sh_eth, from Yoshihiro Shimoda.

7) Revert skge PCI mapping changes that are causing crashes for some

8) IPV4 route lookups fill in the wildcarded fields of the given flow
   lookup key passed in, which is fine most of the time as this is
   exactly what the caller's want.  However there are a few cases that
   want to retain the original flow key values afterwards, so handle
   those cases properly.  Fix from Julian Anastasov.

9) IGB/IXGBE VF lookup bug fixes from Greg Rose.

10) Properly null terminate filename passed to ethtool flash device
    method, from Ben Hutchings.

11) S3 resume fix in via-velocity from David Lv.

12) Fix double SKB free during xmit failure in CAIF, from Dmitry

3682a3946d PCI: Fix pci cardbus removal
During test busn_res allocation with cardbus, found pci card removal is not
working anymore, and it turns out it is broken by:

|commit 79cc9601c3
|Date:   Tue Nov 22 21:06:53 2011 -0800
|
|    PCI: Only call pci_stop_bus_device() one time for child devices at remove

The above changed the behavior of pci_remove_behind_bridge that
yenta_cardbus depended on.  So restore the old behavoir of
pci_remove_behind_bridge (which requires stopping and removing of all
devices) by:

1. rename pci_remove_behind_bridge to __pci_remove_behind_bridge, and let
   __pci_remove_bus_device() call it instead.
2. add pci_stop_behind_bridge that will stop devices behind a bridge
3. add back pci_remove_behind_bridge that will stop and remove devices
   under bridge.

8161fe91d8 PCI: set pci sriov page size before reading SRIOV BAR
For an SRIOV device, PCI_SRIOV_SYS_PGSIZE should be set before
the PCI_SRIOV_BAR are queried.  The sys pagesize defaults to 4k,
so this change is required on powerpc box with 64k base page size.
    
This is a regression caused due to moving SRIOV init to sriov_enable().

This is default, a manual workaround (without this patch)

V2: Add dev_warn if the workaround is hit. This should reveal
how common such setups are (via google) and point to possible

04da0c8196 xfs: use a normal shrinker for the dquot freelist
Stop reusing dquots from the freelist when allocating new ones directly, and
implement a shrinker that actually follows the specifications for the
interface.  The shrinker implementation is still highly suboptimal at this
point, but we can gradually work on it.

This also fixes an bug in the previous lock ordering, where we would take
the hash and dqlist locks inside of the freelist lock against the normal
lock ordering.  This is only solvable by introducing the dispose list,
and thus not when using direct reclaim of unused dquots for new allocations.

As a side-effect the quota upper bound and used to free ratio values in
/proc/fs/xfs/xqm are set to 0 as these values don't make any sense in the
new world order.

1e056dddab ARM: OMAP2xxx: PM: fix OMAP2xxx-specific UART idle bug in v3.3
On OMAP2420-based systems, the PM code ignores the state of the UART
functional clocks when determining what idle state to enter.  This
breaks the serial port now that the UART driver's clock behavior can
be controlled via the PM autosuspend timeout.

To fix, remove the special-case idle handling for the UARTs in the
OMAP2420/2430 PM idle code added by commit
4af4016c53 ("OMAP3: PM: UART: disable
clocks when idle and off-mode support").

Tested on Nokia N800.  This patch is a collaboration between Tony
Lindgren <tony@atomide.com> and Paul Walmsley <paul@pwsan.com>.

7205335358 ARM: orion: Fix USB phy for orion5x.
The patch "ARM: orion: Consolidate USB platform setup code.", commit
4fcd3f374a broke USB on TS-7800 and
other orion5x boards, because the wrong type of PHY was being passed
to the EHCI driver in the platform data. Orion5x needs EHCI_PHY_ORION
and all the others want EHCI_PHY_NA.

Allow the mach- code to tell the generic plat-orion code which USB PHY
enum to place into the platform data.

Version 2: Rebase to v3.3-rc2.

b065403710 ARM: orion: Fix Orion5x GPIO regression from MPP cleanup
Patchset "ARM: orion: Refactor the MPP code common in the orion
platform" broke at least Orion5x based platforms. These platforms have
pins configured as GPIO when the selector is not 0x0. However the
common code assumes the selector is always 0x0 for a GPIO lines. It
then ignores the GPIO bits in the MPP definitions, resulting in that
Orion5x machines cannot correctly configure there GPIO lines.

The Fix removes the assumption that the selector is always 0x0.
In order that none GPIO configurations are correctly blocked,
Kirkwood and mv78xx0 MPP definitions are corrected to only set the
GPIO bits for GPIO configurations.

This third version, which does not contain any whitespace changes,
and is rebased on v3.3-rc2.

otherwise the allmodconfig build fails on sparc64.
