Pull regmap PM fix from Mark Brown:
"A simple fix to stop us leaking a runtime PM reference in the case
where we fail to enable a device."
* tag 'regmap-v3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/broonie/regmap:

Even in failed case of pm_runtime_get_sync, the usage_count
is incremented. In order to keep the usage_count with correct
value and runtime power management to behave correctly, call
pm_runtime_put(_sync) in such case.

git://git.kernel.org/pub/scm/linux/kernel/git/tyhicks/ecryptfs
Pull ecryptfs fixes from Tyler Hicks:
"Minor code cleanups and new Kconfig option to disable /dev/ecryptfs
The code cleanups fix up W=1 compiler warnings and some unnecessary
checks. The new Kconfig option, defaulting to N, allows the rarely
used eCryptfs kernel to userspace communication channel to be compiled
out. This may be the first step in it being eventually removed."
Hmm. I'm not sure whether these should be called "fixes", and it
probably should have gone in the merge window. But I'll let it slide.

When the userspace messaging (for the less common case of userspace key
wrap/unwrap via ecryptfsd) is not needed, allow eCryptfs to build with
it removed. This saves on kernel code size and reduces potential attack
surface by removing the /dev/ecryptfs node.

It is sufficient to check the return code of

This is meant to remove a compiler warning. It should not make any

payload_len should be initialized when it is passed to
write_tag_64_packet() as a pointer. If that call fails, this function

Currently we use the link register to branch up high in the early MMU on
syscall entry path. Unfortunately, this trashes the link stack as the
address we are going to is not associated with the earlier mflr.
This patch simply converts us to used the count register (volatile over
syscalls anyway) instead. This is much better at predicting in this
scenario and doesn't trash link stack causing a bunch of additional
branch mispredicts later. Benchmarking this on POWER8 saves a bunch of
cycles on Anton's null syscall benchmark here:

virtio_rng feeds the randomness buffer handed by the core directly
into the scatterlist, since commit bb347d98079a547e80bd4722dee1de61e4dca0e8.
However, if CONFIG_HW_RANDOM=m, the static buffer isn't a linear address
(at least on most archs). We could fix this in virtio_rng, but it's actually
far easier to just do it in the core as virtio_rng would have to allocate
a buffer every time (it doesn't know how much the core will want to read).

Setting net.ipv6.conf.<interface>.accept_ra=2 causes the kernel
to accept RAs even when forwarding is enabled. However, enabling
forwarding purges all default routes on the system, breaking
connectivity until the next RA is received. Fix this by not
purging default routes on interfaces that have accept_ra=2.

up stack ndo_start_xmit already hold lock.
fec_enet_start_xmit needn't spin lock.
stat_xmit just update fep->cur_tx
fec_enet_tx just update fep->dirty_tx
Reserve a empty bdb to check full or empty
cur_tx == dirty_tx means full
cur_tx == dirty_tx +1 means empty
So needn't is_full variable.
Fix spin lock deadlock

This is a resubmission.
Added kfree() in ax88179_get_eeprom to prevent memory leakage.
Modified "__le16 rxctl" to "u16 rxctl" in "struct ax88179_data" and removed pointless casts.
Removed asix_init and asix_exit functions and added "module_usb_driver(ax88179_178a_driver)".
Fixed endianness issue on big endian systems and verified this driver on iBook G4.
Removed steps that change net->features in ax88179_set_features function.
Added "const" to ethtool_ops structure and fixed the coding style of AX88179_BULKIN_SIZE array.
Fixed the issue that the default MTU is not 1500.
Added ax88179_change_mtu function and enabled the hardware jumbo frame function to support an
MTU higher than 1500.
Fixed indentation and empty line coding style errors.
The _nopm version usb functions were added to access register in suspend and resume functions.
Serveral variables allocted dynamically were removed and replaced by stack variables.
ax88179_get_eeprom were modified from asix_get_eeprom in asix_common.
This patch adds a driver for ASIX's AX88179 family of USB 3.0/2.0
to gigabit ethernet adapters. It's based on the AX88xxx driver but
the usb commands used to access registers for AX88179 are completely different.
This driver had been verified on x86 system with AX88179/AX88178A and
Sitcomm LN-032 USB dongles.

This patch doesn't change how the code works because in the current
kernel gfp is always GFP_KERNEL. But gfp was obviously intended
instead of GFP_KERNEL.

I had a report recently of a user trying to use dropwatch to localise some frame
loss, and they were getting false positives. Turned out they were using a user
space SCTP stack that used raw sockets to grab frames. When we don't have a
registered protocol for a given packet, we record it as a drop, even if a raw
socket receieves the frame. We should only record the drop in the event a raw
socket doesnt exist to receive the frames
Tested by the reported successfully

This is another flurry of fixes intended for the 3.9 stream...
A mac80211 pull from Johannes:
"Seth fixes a stupid bug I introduced into one of his earlier patches,
Chun-Yeow fixes mesh forwarding and Felix fixes monitor mode. I myself
fixed a small locking issue and, the biggest change here, removed some
nl80211 information with which sometimes the per wiphy information was
getting too large for the typical 4k-minus-overhead. In my -next tree I
have a patch to allow splitting that and add back the information
removed now."
An iwlwifi pull from Johannes:
"I have a fix for a pretty important bug regarding DMA mapping, that
could cause the DMA engine to overwrite data we wanted to send to it, so
that the next time we send it it would be bad. This particularly affects
calibration results. Other than that, three little fixes for the MVM
driver."
But wait, there's more!
Avinash Patil fixes an incorrectly timed delay in mwifiex.
Bing Zhao prevents a crash in SD8688 caused by failing to properly
set a flag before issuing a command.
Felix Fietkau is the big here this time, providing a trio of minor
ath9k fixes and correcting the advertised interface combinations for
rt2x00 when mesh support is disabled.
Finally, Hauke Mehrtens gives us a patch that correctlin initializes
a spin lock in the bcma code.
Please let me know if there are problems!

For SD8688, FUNC_INIT command is queued before fw_ready flag is
set. This causes the following crash as lbs_thread blocks any
command if fw_ready is not set.

Fix it by setting fw_ready flag prior to queuing FUNC_INIT command.

If CONFIG_MAC80211_MESH is not set, cfg80211 will now allow advertising
interface combinations with NL80211_IFTYPE_MESH_POINT present.
Add appropriate ifdefs to avoid running into errors.
