Driver incorrectly validates command completion: instead of waiting
for a command to be acknowledged it continues execution. Most of the
time driver gets acknowledge of the command completion in a tasklet
before it executes the next one. But sometimes it sends the next
command before it gets acknowledge for the previous one. In such a
case one of the following error messages appear in the log:
Failed to send SYSTEM_CONFIG: Already sending a command.
Failed to send ASSOCIATE: Already sending a command.
Failed to send TX_POWER: Already sending a command.
After that you need to reload the driver to get it working again.
This bug occurs during roaming (reported by Sam Varshavchik)

The 'ath9k_hw_update_regulatory_maxpower'
helper function has been introduced by
commit a55f858852
(ath9k_hw: Cleanup TX power calculation for AR9287).
Updating of the max_power_level value has been moved
into the helper function in that change, however the
removed code from 'ath9k_hw_ar9287_set_txpower' has
not been replaced with a call of the new helper
function.
Due to that missing call, retrieving tx power for 2x2
and 3x3 chainmask is not handled properly. During the
calculation of the tx power for 2x2 and 3x3 chainmasks
the values are reduced. Those reductions must be
compensated during retrieving.
Fix this by adding the missing call of the helper
function.

In order to unifying regulatory limit handling
commit ca2c68cc7b
(ath9k_hw: clean up tx power handling) introduced
a new helper function 'ath9k_hw_apply_txpower',
and the direct calls of 'ah->eep_ops->set_txpower'
has been replaced by a call of the helper function.
This caused a change in the behaviour of the
'ath9k_hw_set_txpowerlimit' function. The purpose
of that function is to calculate and store the
rate txpower table and the regulatory limit without
touching the hardware registers. Before the commit,
the 'test' parameter of the function was passed to
the 'ah->eep_ops->set_txpower'. Now the calling of
the 'set_txpower' function happens indirectly through
'ath9k_hw_apply_txpower', so the 'test' argument of
the 'set_txpower' is always 'false'.
This patch restores the original behaviour of
'ath9k_hw_set_txpowerlimit' by adding a new
argument to 'ath9k_hw_apply_txpower.'

Using coherent DMA memory with the OMAP DMA engine results in
unpredictable behaviour due to memory ordering issues; as things stand,
there is no guarantee that data written to coherent DMA memory will be
visible to the DMA hardware.
This is because the OMAP dma_write() accessor contains no barriers,
necessary on ARMv6 and above. The effect of this can be seen in comments
in the OMAP serial driver, which incorrectly talks about cache flushing
for the coherent DMA stuff.
Rather than adding barriers to the accessors, add it in the DMA support
code just before we enable DMA, and just after we disable DMA. This
avoids having barriers for every DMA register access.

The ARM PCS mandates that the length and stride bits of the fpscr are
cleared on entry to and return from a public interface. Although signal
handlers run asynchronously with respect to the interrupted function,
the handler itself expects to run as though it has been called like a
normal function.
This patch updates the state mirroring the VFP hardware before entry to
a signal handler so that it adheres to the PCS. Furthermore, we disable
VFP to ensure that we trap on any floating point operation performed by
the signal handler and synchronise the hardware appropriately. A check
is inserted after the signal handler to avoid redundant flushing if VFP
was not used.

Erratum #326103 ("FSR write bit incorrect on a SWP to read-only memory")
only affects the ARM 1136 core prior to r1p0. The workaround
disassembles the faulting instruction to determine whether it was a read
or write access on all v6 cores.
An issue has been reported on the ARM 11MPCore whereby loading the
faulting instruction may happen in parallel with that page being
unmapped, resulting in a deadlock due to the lack of TLB broadcasting
in hardware:
http://lists.infradead.org/pipermail/linux-arm-kernel/2012-March/091561.html
This patch limits the workaround so that it is only used on affected
cores, which are known to be UP only. Other v6 cores can rely on the

made the assumption that all the phy ids an lldd registers to libsas are
unique. However, in the "multi-chip" case mvsas does a rather annoying
duplication of phy ids in the array passed to libsas. So, for example,
chip0 has phy0-3 at ha phy index 0-3 and chip1 has its phy0-3 at ha phy
index 4-7. The more natural model would be to create a scsi_host (and
sas_ha) per chip (controller), but for now revert the naming fix which
unfortunately means dealing with unpredictable end-device names for a
bit longer.

16) Dummy device needs ->ndo_uninit handler to properly handle
->ndo_init failures. From Hiroaki SHIMODA.
17) Fix TX fragmentation in ath9k driver, from Sujith Manoharan.
18) Missing RTNL lock in ixgbe PM resume, from Benjamin Poirier.
19) Missing iounmap in farsync WAN driver, from Julia Lawall.
20) With LRO/GRO, tcp_grow_window() is easily tricked into not growing
the receive window properly, and this hurts performance. Fix from
Eric Dumazet.
21) Network namespace init failure can leak net_generic data, fix from
Julian Anastasov.
22) Fix skb_over_panic due to mis-accounting in TCP for partially ACK'd
SKBs. From Eric Dumazet.
23) New IDs for qmi_wwan driver, from Bjørn Mork.
24) Fix races in ax25_exit(), from Eric W. Biederman.
25) IPV6 TCP doesn't handle TCP_MAXSEG socket option properly, copy over
logic from the IPV4 side. From Neal Cardwell.

The following build warning is seen in some configurations.
drivers/hwmon/ad7314.c: In function 'ad7314_show_temperature':
drivers/hwmon/ad7314.c:70: warning: 'data' may be used uninitialized in this function
Fix by overloading the return value from ad7314_spi_read with both data and
error code (the returned data is really u16 and needs to be converted into a
signed value anyway).

This gets rid of the unused default senses array, and replaces the
incorrect use of IRQ_TYPE_NONE with the new IRQ_TYPE_DEFAULT for
the initial set_trigger() call when mapping an interrupt.
This in turn makes us read the HW state and update the irq desc
accordingly.

This is meant typically to allow a PIC driver's irq domain map() callback
to establish sane defaults for the interrupt (and make sure that the HW
and the irq_desc are in sync as far as the trigger is concerned).
The irq core may not call the set_trigger callback if it thinks the
trigger is already set to the right setting, so we need to ensure new
descriptors are properly synchronized with the hardware.

mpic_is_ipi() takes a virq and immediately converts it to a hw_irq.
However, one of the two call sites calls it with a ... hw_irq. The
other call site also happens to have the hw_irq at hand, so let's
change it to just take that as an argument. Also change mpic_is_tm()
for consistency.
