Input: adp5588-keys - get value from data out when dir is out

As discussed here: http://ez.analog.com/message/35852, the 5587 revC and
5588 revB spec sheets contain a mistake in the GPIO_DAT_STATx register
description.

According to R.Shnell at ADI, as well as my own observations, it should
read: "GPIO data status (shows GPIO state when read for inputs)".

This commit changes the get value function accordingly.

Input: da9052_onkey - use correct register bit for key status

The wrong register bit of the DA9052/3 PMIC registers was
used to determine the status on the ONKEY.

Also a failure in reading the status register will no longer
result in the work queue being rescheduled as that would result
in a (potentially) endless retry.

nfsd: fix lost nfserrno() call in nfsd_setattr()

There is a regression in
	208d0ac 2014-01-07 nfsd4: break only delegations when appropriate
which deletes an nfserrno() call in nfsd_setattr() (by accident,
probably), and NFSD becomes ignoring an error from VFS.

net: af_key: fix sleeping under rcu

There's a kmalloc with GFP_KERNEL in a helper

called under rcu_read_lock. Adjust pfkey_sadb2xfrm_user_sec_ctx to have
a gfp argument and adjust the users.

selinux: add gfp argument to security_xfrm_policy_alloc and fix callers

security_xfrm_policy_alloc can be called in atomic context so the
allocation should be done with GFP_ATOMIC. Add an argument to let the
callers choose the appropriate way. In order to do so a gfp argument
needs to be added to the method xfrm_policy_alloc_security in struct
security_operations and to the internal function
selinux_xfrm_alloc_user. After that switch to GFP_ATOMIC in the atomic
callers and leave GFP_KERNEL as before for the rest.
The path that needed the gfp argument addition is:
security_xfrm_policy_alloc -> security_ops.xfrm_policy_alloc_security ->
all users of xfrm_policy_alloc_security (e.g. selinux_xfrm_policy_alloc) ->
selinux_xfrm_alloc_user (here the allocation used to be GFP_KERNEL only)

Now adding a gfp argument to selinux_xfrm_alloc_user requires us to also
add it to security_context_to_sid which is used inside and prior to this
patch did only GFP_KERNEL allocation. So add gfp argument to
security_context_to_sid and adjust all of its callers as well.

ath9k: Fix sequence number assignment for non-data frames

Since commit 558ff225de80ac95b132d3a115ddadcd64498b4f (ath9k: fix
ps-poll responses under a-mpdu sessions) non-data frames would have
gotten a sequence number from a TIDs sequence counter instead of
using the global sequence counter.

This can lead to instable connections.

To fix this only select the correct TID if we are processing a
data frame. Furthermore, prevent non-data frames to get a sequence
number from a TID sequence counter by adding a check to
ath_tx_setup_buffer.

Revert "rt2x00: rt2800lib: Update BBP register initialization for RT53xx"

This reverts commit eac40d9631a7db43570df859fa8a9922e9623607. It cause
random connection drops on RT5390 PCI adapters.

On Mediatek there is different driver version available for RT53xx chip
based on bus type (2.5.0.3 for PCI and 2.6.1.3 for USB). Hence possibly
we should set registers differently based on bus type. But is also
possible that new driver (i.e. 2.6.1.3) was not verified on RT53xx USB.

Until we figure out how to initialize registers properly for RT53xx just
revert commit eac40d9631a7db43570df859fa8a9922e9623607 since it cause
regression.

sparc64: don't treat 64-bit syscall return codes as 32-bit

When checking a system call return code for an error,
linux_sparc_syscall was sign-extending the lower 32-bit value and
comparing it to -ERESTART_RESTARTBLOCK. lseek can return valid return
codes whose lower 32-bits alone would indicate a failure (such as 4G-1).
Use the whole 64-bit value to check for errors. Only the 32-bit path
should sign extend the lower 32-bit value.

ATHEROS-ALX: Use dma_set_mask_and_coherent and fix a bug

1. For the 64 bits dma mask use dma_set_mask_and_coherent instead of
   dma_set_mask and dma_set_coherent_mask.

2. For the 32 bits dma mask dma_set_coherent_mask is only called if
   dma_set_mask fails, which is unusual. Assuming this as a bug, fixes
   it by replacing calls to dma_set_mask and dma_set_coherent_mask by a
