Linus Torvalds e95003c3f9 NFS client bugfixes for Linux 3.14
Highlights include stable fixes for the following bugs:
 
 - General performance regression due to NFS_INO_INVALID_LABEL being set
   when the server doesn't support labeled NFS
 - Hang in the RPC code due to a socket out-of-buffer race
 - Infinite loop when trying to establish the NFSv4 lease
 - Use-after-free bug in the RPCSEC gss code.
 - nfs4_select_rw_stateid is returning with a non-zero error value on success
 
 Other bug fixes:
 
 - Potential memory scribble in the RPC bi-directional RPC code
 - Pipe version reference leak
 - Use the correct net namespace in the new NFSv4 migration code

Couple of small issues solved:
   - Suspend/Resume call-backs require CONFIG_PM_SLEEP
   - Some drivers written for 32bit architectures fail when compiled
     with a 64bit compiler. The fixes will future proof the drivers.

 "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"

The PHY library has been subject to some changes, new drivers and DT
interactions over the past few months. Add myself as a maintainer for
the core PHY library parts and drivers. Make sure the PHY library entry
also covers the Device Tree files which have a close interaction with
the MDIO bus, PHY connection and Ethernet PHY mode parsing.

Ben Dooks f15c586d1d of_mdio: fix phy interrupt passing
The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.

Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:

- Set phy->irq if node has irq property and mdio->irq is NULL
- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above

This fixes the issue:
 net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI

to the correct:
 net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

Thomas Petazzoni 4b636b535d net: ethernet: update dependency and help text of mvneta
With the introduction of the support for Armada 375 and Armada 38x,
the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
driver can no longer work. This commit replaces this dependency by a
dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
driver.

In addition to this, it takes this opportunity to adjust the
description and help text to indicate that the driver can is also used
for Armada 38x. Note that Armada 375 cannot use this driver as it has
a completely different networking unit, which will require a separate
driver.

John W. Linville says:

====================
Please pull this batch of fixes intended for the 3.14 stream...

For the iwlwifi one, Emmanuel says:

"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."

On top of that...

Dan Carpenter fixes a typo/thinko in ath5k.

Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),
and one which fixes an incorrect return code when failing to enable
the NIC.

Russell King fixes a NULL pointer dereference in hostap.

Stanislaw Gruszka fixes a DMA coherence issue in the rtl8187 driver.

Please let me know if there are problems!

Daniel Borkmann ffd5939381 net: sctp: fix sctp_connectx abi for ia32 emulation/compat mode
SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit
emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of
'struct sctp_getaddrs_old' which includes a struct sockaddr pointer,
sizeof(param) check will always fail in kernel as the structure in
64bit kernel space is 4bytes larger than for user binaries compiled
in 32bit mode. Thus, applications making use of sctp_connectx() won't
be able to run under such circumstances.

Introduce a compat interface in the kernel to deal with such
situations by using a 'struct compat_sctp_getaddrs_old' structure
where user data is copied into it, and then sucessively transformed
into a 'struct sctp_getaddrs_old' structure with the help of
compat_ptr(). That fixes sctp_connectx() abi without any changes
needed in user space, and lets the SCTP test suite pass when compiled
in 32bit and run on 64bit kernels.

Some hardware may not support standard 64x64 cursors.  Add
a drm cap to query the cursor size from the kernel.  Some examples
include radeon CIK parts (128x128 cursors) and armada (32x64 or 64x32).
This allows things like device specific ddxes to remove asics specific
logic and also allows xf86-video-modesetting to work properly with hw
cursors on this hardware. Default to 64 if the driver doesn't specify
a size.

Commit a55409066 ("drm/nv50-: map TTM_PL_SYSTEM through a BAR for CPU

mem->mm_node is not a nouveau_mem for AGP-using pre-NV50 cards, but a
drm_mm_node, as created by the ttm_bo_manager_func. As such, extend the
untiled check to explicitly include all pre-nv50 cards.
