There are some corner cases where the driver could get stuck with a full
tid queue that is paused, leading to a software tx queue hang.
Since the tx queueing rework, pausing per-tid queues on aggregation
session setup is no longer necessary. The driver will assign sequence
numbers to buffered frames when a new session is established, in order
to get the correct starting sequence number.
mac80211 prevents new frames from entering the queue during setup.

When the amount of noise fluctuates strongly, low immunity settings
can sometimes disrupt signal detection on AR913x chips. When that
happens, no OFDM/CCK errors are reported anymore, and ANI tunes the
radio to the lowest immunity settings.
Usually rx/tx fails as well in that case.
To fix this, keep noise immunity settings at or above ANI default level,
which will keep radio parameters at or above INI values.

When we're performing reauthentication (in order to elevate the
security level from an unauthenticated key to an authenticated one) we
do not need to issue any encryption command once authentication
completes. Since the trigger for the encryption HCI command is the
ENCRYPT_PEND flag this flag should not be set in this scenario.
Instead, the REAUTH_PEND flag takes care of all necessary steps for
reauthentication.

Commit 1c2e004183 introduced an event handler for the encryption key
refresh complete event with the intent of fixing some LE/SMP cases.
However, this event is shared with BR/EDR and there we actually want to
act only on the auth_complete event (which comes after the key refresh).
If we do not do this we may trigger an L2CAP Connect Request too early
and cause the remote side to return a security block error.

This reverts commit d2bee8fb6e.
Enabling autosuspend for Intel Bluetooth devices has been shown to not
work reliable. It does work for some people with certain combinations
of USB host controllers, but for others it puts the device to sleep and
it will not wake up for any event.
These events can be important ones like HCI Inquiry Complete or HCI
Connection Request. The events will arrive as soon as you poke the
device with a new command, but that is not something we can do in
these cases.
Initially there were patches to the xHCI USB controller that fixed
this for some people, but not for all. This could be well a problem
somewhere in the USB subsystem or in the USB host controllers or
just plain a hardware issue somewhere. At this moment we just do
not know and the only safe action is to revert this patch.

brcmfmac has been broken on my cubietruck with a BCM43362:

brcmfmac: brcmf_c_preinit_dcmds: Firmware version = wl0:
Apr 22 2013 14:50:00 version 5.90.195.89.6 FWID 01-b30a427d
since commit 53036261033: "brcmfmac: update core reset and disable routines".
The problem is that since this commit brcmf_chip_ai_resetcore no longer sets
BCMA_IOCTL itself before bringing the core out of reset, instead relying on
brcmf_chip_ai_coredisable to do so. But brcmf_chip_ai_coredisable is a nop
of the chip is already in reset. This patch modifies brcmf_chip_ai_coredisable
to always set BCMA_IOCTL even if the core is already in reset.
This fixes brcmfmac hanging in firmware loading on my board.

Implement a recv budget so that in cases of high traffic we still allow other

Without this, we can encounter a host of issues during high wireless traffic
reception depending on system load including rcu stall's detected (ARM),
soft lockups, failure to service critical tasks such as watchdog resets,
and triggering of the tx stuck tasklet.
The same thing was proposed previously by Ben:

Allow switching back to legacy Tx columns so we'll stop doing

Despite having low legacy rates in the LQ table lower entries
it doesn't help much in case we're doing aggregations as the

After being idle for a long time (>5sec) the rs statistics
will be stale so we prefer to reset rs and start from legacy
rates again. This gives better results when the attenuation
increased signficantly (e.g. we got further from the AP) and
after a while we start Tx
Note that the first Tx after the idle period will still go out
in the old modulation and rate but this seemed a simpler approach
compared to adding a timer or modifying mac80211 for this.

This patch fixes I/O errors with the sym53c8xx_2 driver when the disk
returns QUEUE FULL status.
When the controller encounters an error (including QUEUE FULL or BUSY
status), it aborts all not yet submitted requests in the function
sym_dequeue_from_squeue.
This function aborts them with DID_SOFT_ERROR.
If the disk has full tag queue, the request that caused the overflow is
aborted with QUEUE FULL status (and the scsi midlayer properly retries
it until it is accepted by the disk), but the sym53c8xx_2 driver aborts
the following requests with DID_SOFT_ERROR --- for them, the midlayer
does just a few retries and then signals the error up to sd.
The result is that disk returning QUEUE FULL causes request failures.
The error was reproduced on 53c895 with COMPAQ BD03685A24 disk
(rebranded ST336607LC) with command queue 48 or 64 tags. The disk has
64 tags, but under some access patterns it return QUEUE FULL when there
are less than 64 pending tags. The SCSI specification allows returning
QUEUE FULL anytime and it is up to the host to retry.

Commit 8f619b5429 ("powerpc/ppc64: Do not turn AIL (reloc-on
interrupts) too early") added code to set the AIL bit in the LPCR
without checking whether the kernel is running in hypervisor mode. The
result is that when the kernel is running as a guest (i.e., under
PowerKVM or PowerVM), the processor takes a privileged instruction
interrupt at that point, causing a panic. The visible result is that
the kernel hangs after printing "returning from prom_init".
This fixes it by checking for hypervisor mode being available before
setting LPCR. If we are not in hypervisor mode, we enable relocation-on
interrupts later in pSeries_setup_arch using the H_SET_MODE hcall.

Merge tag 'ntb-3.15' of git://github.com/jonmason/ntb
Pull PCIe non-transparent bridge fixes and features from Jon Mason:
"NTB driver bug fixes to address issues in list traversal, skb leak in
ntb_netdev, a typo, and a leak of msix entries in the error path.
Clean ups of the event handling logic, as well as a overall style
cleanup. Finally, the driver was converted to use the new
pci_enable_msix_range logic (and the refactoring to go along with it)"
* tag 'ntb-3.15' of git://github.com/jonmason/ntb:
ntb: Use pci_enable_msix_range() instead of pci_enable_msix()
ntb: Split ntb_setup_msix() into separate BWD/SNB routines
ntb: Use pci_msix_vec_count() to obtain number of MSI-Xs
NTB: Code Style Clean-up
NTB: client event cleanup
ntb: Fix leakage of ntb_device::msix_entries[] array
NTB: Fix typo in setting one translation register
ntb_netdev: Fix skb free issue in open
ntb_netdev: Fix list_for_each_entry exit issue
The vfs merge caused a latent bug to show up:

where the reason is that <linux/ceph_debug.h> is included much too late
for the "pr_fmt()" define.
The include of <linux/ceph_debug.h> needs to be the first include in the
file, but fs/ceph/ioctl.c had for some reason missed that, and it wasn't
noticeable until some unrelated header file changes brought in an
indirect earlier include of <linux/kernel.h>.

Pull vfs updates from Al Viro:
"The first vfs pile, with deep apologies for being very late in this
window.
Assorted cleanups and fixes, plus a large preparatory part of iov_iter
work. There's a lot more of that, but it'll probably go into the next
merge window - it *does* shape up nicely, removes a lot of
boilerplate, gets rid of locking inconsistencie between aio_write and
splice_write and I hope to get Kent's direct-io rewrite merged into
the same queue, but some of the stuff after this point is having
(mostly trivial) conflicts with the things already merged into
mainline and with some I want more testing.
This one passes LTP and xfstests without regressions, in addition to
usual beating. BTW, readahead02 in ltp syscalls testsuite has started
giving failures since "mm/readahead.c: fix readahead failure for
memoryless NUMA nodes and limit readahead pages" - might be a false
positive, might be a real regression..."
