e76d67f035 mac80211: mesh: factor out common plink close/estab code
Reject and accepted close events always put the host in the
holding state and compute a reason code based only on the
current state.  Likewise on establish we always do the same
setup.  Put these in functions to save some duplicated code.

4efec45134 mac80211: consolidate calls to plink_frame_tx
Do all frame transfers in one place at the end of the
big switch statements.  sta->plid and sta->reason can
be passed in any case, since they are only used for
the frames that need them.  Remove assignments to locals
for values already stored in the sta structure.

According to IEEE 802.11-2012 (8.4.2.104), no peering
management element exists with length 7. This code is checking
to see if llid is present to ignore close frames with different
llid, which would be IEs with length 8.

2e3049b79c mac80211: do not compute offset from ssn in Rx AMPDU reordering buffer
Currently, frames that go into the reordering buffer are stored at
index ieee80211_sn_sub(sn, tid_rx->ssn) % tid_rx->buf_size.

The offset calculation to the starting sequence number (SSN) is
useless and just adds overhead so simply use sn % tid_rx->buf_size.

This means the reordering buffer will start to be filled somewhere
in the middle (at SSN % buf_size) and continue to get used from
there, but there's no reason to start from the beginning.

Old userspace sending either flag will have it treated as

also send both the no-ir flag and the old no-ibss flags.
Newer userspace will have to be aware of older kernels.

96039f735e ARM: mvebu: re-enable PCIe on Armada 370 DB
Commit 14fd8ed0a7 ("ARM: mvebu: Relocate Armada 370/XP PCIe
device tree nodes") relocated the PCIe controller DT nodes one level
up in the Device Tree, to reflect a more correct representation of the
hardware introduced by the mvebu-mbus Device Tree binding.

However, while most of the boards were properly adjusted accordingly,
the Armada 370 DB board was left unchanged, and therefore, PCIe is
seen as not enabled on this board. This patch fixes that by moving the
PCIe controller node one level-up in armada-370-db.dts.

b6dda00cdd ARM: mvebu: use the virtual CPU registers to access coherency registers
The Armada XP provides a mechanism called "virtual CPU registers" or
"per-CPU register banking", to access the per-CPU registers of the
current CPU, without having to worry about finding on which CPU we're
running. CPU0 has its registers at 0x21800, CPU1 at 0x21900, CPU2 at
0x21A00 and CPU3 at 0x21B00. The virtual registers accessing the
current CPU registers are at 0x21000.

However, in the Device Tree node that provides the register addresses
for the coherency unit (which is responsible for ensuring coherency
between processors, and I/O coherency between processors and the
DMA-capable devices), a mistake was made: the CPU0-specific registers
were specified instead of the virtual CPU registers. This means that
the coherency barrier needed for I/O coherency was not behaving
properly when executed from a CPU different from CPU0. This patch
fixes that by using the virtual CPU registers.

commit b8d181e408 (staging: drm/imx: add drm plane support) added a file

ERROR: "ipu_plane_disable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!
ERROR: "ipu_plane_enable" [drivers/staging/imx-drm/ipuv3-crtc.ko] undefined!

Additionally, it added a call to imx_drm_crtc_id which also fails with a
link error as above.  To fix this, we adjust the make target with the proper
objs, which will change the name of the resulting .ko.  We also add an
EXPORT_SYMBOL_GPL for imx_drm_crtc_id.

cb4855b49d Staging: vt6655-6: potential NULL dereference in hostap_disable_hostapd()
We fixed this to use free_netdev() instead of kfree() but unfortunately
free_netdev() doesn't accept NULL pointers.  Smatch complains about
this, it's not something I discovered through testing.

8778ac6be2 ASoC: Fix build without CONFIG_GPIOLIB
snd_soc_jack_gpio stuff is currently enabled for CONFIG_GPIOLIB
explicitly with ifdef, and this causes build errors on some drivers
such as:
  sound/soc/omap/rx51.c:220:33: error: array type has incomplete element type

Remove ifdef and provide dummy functions for CONFIG_GPIOLIB=n case
instead.

3de00ee4ce staging: comedi: s626: fix value written by s626_set_dac()
I broke `s626_set_dac()` by changing the type of the `dacdata` parameter
from `short` to `unsigned short`.  It's actually designed to take a
signed value in the range -0x1fff to +0x2000 although values above
0x1fff get clamped to 0x1fff.  (We could change the `maxdata` value to
0x1ffe to avoid the clamping, but `maxdata` values are usually a power
of 2 minus 1.)  The bug results in all negative values passed to the
function being changed to +0x1fff by the clamp.  Change the parameter
type to `int16_t` to fix the problem.

d4855e1fc0 tty: Reset hupped state on open
A common security idiom is to hangup the current tty (via vhangup())
after forking but before execing a root shell. This hangs up any
existing opens which other processes may have and ensures subsequent
opens have the necessary permissions to open the root shell tty/pty.

Reset the TTY_HUPPED state after the driver has successfully
returned the opened tty (perform the reset while the tty is locked
to avoid racing with concurrent hangups).
