9f8466c6e0 ARM: vt8500: Add missing NULL terminator in dt_compat
When I tried booting a stih415 Dual core A9 with multi_v7_defconfig, it
failed to boot. The issues seems to be changing by enabling or disabling
VT8550 platform. Having a quick look at dt_compat list, it seems to miss
a NULL terminator, which means of_flat_dt_match will compat check will
cross the boundary of dt_compat and fault at some point , which is what
was happening in my case.

Without this patch if we try to boot multi_v7_defconfig you might notice
that some of the platforms might fault if they fall after vt8500 in
machine-desc list. Other platforms which fall before vt8500 in mdesc list
will not fault.

7e94984495 clk: tegra: remove USB from clk init table
The USB clocks are just clock gates, so no need to set a specific clock.
In fact trying to set a specific clock is just a NOP if the requested
clockrate is the same as those of the parent (clk_m) or will trigger a
WARN_ON() if rates don't match up.

As we are not setting a specific rate, nor activating the clocks at
init, there is no point in keeping the the usb entries in the clock init
table.

This is the pull request for AMD Sun/Hainan support.  I've
split it out separately from my regular fixes stream.  Hainan
is a new SI asic with no UVD or DCE hardware.  The patches are
minimally invasive; basically just pci ids and skipping UVD and
DCE init for this family.  Most of the changes to si.c are just
the golden register tables for the family.

3ccfc1b1d2 Merge branch 'for-davem' of git://git.kernel.org/pub/scm/linux/kernel/git/linville/wireless
John W. Linville says:

====================
This pull request is intended for the 3.10 series.  It contains a
variety of fixes for problems discovered during the merge window and
after 3.10-rc1.

For the mac80211 bits, Johannes says the following:

"This is what I have:
 * a patch from Felix to fix RCU usage in his rate table code
 * a patch from Ilan to add the wdev id to some notifications so they can
   actually be used by userspace
 * Sasha Levin found an issue in how hwsim handles devices
 * a fix for a bug in the wiphy_register() error path that's been there forever
 * three fixes for WoWLAN
 * AP mode frame matching was erroneously giving frames to all virtual AP
   interfaces (reported by Jouni)
 * a fix for HT handling in my CSA changes, found by Sujith
 * a fix for some locking simplifications gone wrong
 * Ben Greear found more cfg80211/mac80211 state confusion
 * and a fix for another bug found by Jouni: local state changes need to be
   reported by mac80211 to cfg80211 so it disconnects properly."

And for the iwlwifi bits, he says:

"I have fixes for a firmware crash during resume, multicast RX,
aggregation and a workaround for a firmware scanning bug."

Along with those...

Albert Pool adds a USB ID to the rtl8192cu driver.

Arend van Spriel restores a driver option support flag that had been
removed from 3.9 due to a bug in that version of the driver.

Felix Fietkau fixes a trio of ath9k issues with a series of small
patches.

Geert Uytterhoeven provides a Kconfig fix for ath9k (which you also
merged, so it isn't in the diff here).

Larry Finger gives us a fix for a build warning on big-endian systems
for rtlwifi.

Rafał Miłecki adds some core IDs to the bcma driver.

Sujith Manoharan fixes a module unloading crash in ath9k, and corrects
some calibration settings for AR9485.

This patch fixes a potential race with concurrently running asynchronous
write requests.  The values for device's RX control register are now
stored in dynamically allocated buffers so each URB submission has it's
own copy.  Doing it the old way is data clobbering prone.

This patch is against latest 'net' tree.

dab73b4eb9 TTY: Fix tty miss restart after we turn off flow-control
I meet emacs hang in start if I do the operation below:
  1: echo 3 > /proc/sys/vm/drop_caches
  2: emacs BigFile
  3: Press CTRL-S follow 2 immediately

Then emacs hang on, CTRL-Q can't resume, the terminal
hang on, you can do nothing with this terminal except
close it.

The reason is before emacs takeover control the tty,
we use CTRL-S to XOFF it. Then when emacs takeover the
control, it may don't use the flow-control, so emacs hang.
This patch fix it.

This patch will fix a kind of strange tty relation hang problem,
I believe I meet it with vim in ssh, and also see below bug report:

421b40a628 tty/vt: Fix vc_deallocate() lock order
Now that the tty port owns the flip buffers and i/o is allowed
from the driver even when no tty is attached, the destruction
of the tty port (and the flip buffers) must ensure that no
outstanding work is pending.

Unfortunately, this creates a lock order problem with the
console_lock (see attached lockdep report [1] below).

For single console deallocation, drop the console_lock prior
to port destruction. When multiple console deallocation,
defer port destruction until the consoles have been
deallocated.

tty_port_destroy() is not required if the port has not
been used; remove from vc_allocate() failure path.

dbd2df859a serial: 8250_dw: Add valid clk pointer check
Commit ffc3ae6dd "serial: 8250_dw: Enable runtime PM" introduced runtime
PM management, which enables/disables the clk without checking if the clk
is valid. However, this driver allows to be probed without a defined clk,
using clock-frequency, as a fallback.

Therefore, on platforms that are device tree probed using clock-frequency
instead of clk, we get an ugly NULL pointer dereference.

This patch fixes it by simply adding a check before accessing the clk api.

5e427ec2d0 x86: Fix bit corruption at CPU resume time
In commit 78d77df715 ("x86-64, init: Do not set NX bits on non-NX
capable hardware") we added the early_pmd_flags that gets the NX bit set
when a CPU supports NX. However, the new variable was marked __initdata,
because the main _use_ of this is in an __init routine.

However, the bit setting happens from secondary_startup_64(), which is
called not only at bootup, but on every secondary CPU start.  Including
resuming from STR and at CPU hotplug time.  So the value cannot be
__initdata.

774d5f14ee NFSv4.1 Fix a pNFS session draining deadlock
On a CB_RECALL the callback service thread flushes the inode using
filemap_flush prior to scheduling the state manager thread to return the
delegation. When pNFS is used and I/O has not yet gone to the data server
servicing the inode, a LAYOUTGET can preceed the I/O. Unlike the async
filemap_flush call, the LAYOUTGET must proceed to completion.

If the state manager starts to recover data while the inode flush is sending
the LAYOUTGET, a deadlock occurs as the callback service thread holds the
single callback session slot until the flushing is done which blocks the state
manager thread, and the state manager thread has set the session draining bit
which puts the inode flush LAYOUTGET RPC to sleep on the forechannel slot
table waitq.

Separate the draining of the back channel from the draining of the fore channel
by moving the NFS4_SESSION_DRAINING bit from session scope into the fore
and back slot tables.  Drain the back channel first allowing the LAYOUTGET
call to proceed (and fail) so the callback service thread frees the callback
slot. Then proceed with draining the forechannel.

90dae4ebf0 gpio: mxs: Use set and clear capabilities of the gpio controller
The current driver doesn't use the set and clear registers found on the
mxs gpio controller.

This leads the generic gpio controller to be using some internal value
to avoid looking up the value stored in the registers, making it behave
pretty much like a cache.

This raises some coherency problem when a gpio is not modified by the
gpio controller, while it can easily be fixed by using the set and clear
registers.

2519f9abce gpio-langwell: fix irq conflicts when DT is not used
When DT is not used IOAPIC does not register irq domain. As result
IOAPIC won't care about gpio-langwell's virq and may cause conflict if
an irq number is equal to gpio-langwell's virq mapped beforehand.

This patch tells gpio_langwell to not ignore irq_base if != 0 and
preferably use it to avoid the conflict.

If DT is used, irq_base can safely be 0.

When CONFIG_I2C=m, meaning we can't build the drivers in with I2C support.
Thus don't allow the drivers to be compiled as built-in when CONFIG_I2C=m.

The real fix though is to break the driver apart into a SPI part, an I2C part
and a common part. But that's something for 3.11 while this is something for
3.10/stable.
