TPC support has been observed to cause some tx power fluctuations on
some devices with at least AR934x and AR938x chips.
Disable it for now until the bugs have been found and fixed

sc->nbcnvifs tracks assigned beacon slots, not enabled beacons.
Therefore, it cannot be used to decide if cur_conf->enable_beacon (bool)
should be updated, or if beacons have been enabled already.
With the current code (depending on the order of calls), beacons often
do not get enabled in an AP+STA setup.
To fix tracking of enabled beacons, convert cur_conf->enable_beacon to a
bitmask of enabled beacon slots.

Master change notifications may occur other than when joining or
leaving a bridge, for example when being added to or removed from
a bond or Open vSwitch.
Previously in those cases rocker_port_bridge_leave() was called
which results in a null-pointer dereference as rocker_port->bridge_dev
is NULL because there is no bridge device.
This patch makes provision for doing nothing in such cases.

On s390x, gcc 4.8 compiles this part of tcp_v6_early_demux()
struct dst_entry *dst = sk->sk_rx_dst;
if (dst)
dst = dst_check(dst, inet6_sk(sk)->rx_dst_cookie);
to code reading sk->sk_rx_dst twice, once for the test and once for
the argument of ip6_dst_check() (dst_check() is inline). This allows
ip6_dst_check() to be called with null first argument, causing a crash.
Protect sk->sk_rx_dst access by READ_ONCE() both in IPv4 and IPv6
TCP early demux code.

Statistics' state-machine in bnx2x driver must be synced with various driver
flows, but its current locking scheme manages to be wasteful [using 2 locks +
additional local variable] and prone to race-conditions at the same time,
as the state-machine and 'action' are being accessed under different locks.
In addition, current 'safe exec' isn't in fact safe, since the only guarantee
it gives is that DMA transactions are over, but ramrods might still be running.
This patch cleans up said logic, leaving us with a single lock for the entire
flow and removing the possible races.
Changes from v2:
- Switched into mutex locking from semaphore locking.
- Release locks on error flows.
Changes from v1:
Failure to acquire lock fails flow instead of printing a warning and
allowing access to the critical section.

====================
pull-request: can 2015-03-22
this is a pull-request of 7 patches for net/master.
Ahmed S. Darwish fixes another two problems in the kvaser_usb driver. A patch
by Colin Ian King for the gs_usb driver adds a missing check for kzalloc
allocation failures. Two patches by Stephane Grosjean for the peak_usb driver
add missing support for ISO / non-ISO mode switching. Andri Yngvason
contributes a patch to fix the state handling in the flexcan driver. The last
patch by Andreas Werner for the flexcan driver add missing EPROBE_DEFER
handling for the transceiver regulator.

Return EPROBE_DEFER if Regulator returns EPROBE_DEFER
If the Flexcan driver is built into kernel and a regulator is used to
enable the CAN transceiver, the Flexcan driver may not use the regulator.
When initializing the Flexcan device with a regulator defined in the device
tree, but not initialized, the regulator subsystem returns EPROBE_DEFER, hence
the Flexcan init fails.
The solution for this is to return EPROBE_DEFER if regulator is not initialized
and wait until the regulator is initialized.

Current driver code arbitrarily assumes a max outstanding tx
value of 16 parallel transmissions. Meanwhile, the device
firmware provides its actual maximum inside its reply to the
CMD_GET_SOFTWARE_INFO message.
Under heavy tx traffic, if the interleaved transmissions count
increases above the limit reported by firmware, the firmware
breaks up badly, reports a massive list of internal errors, and
the candump traces hardly matches the actual frames sent and
received.
On the other hand, in certain models, the firmware can support
up to 48 tx URBs instead of just 16, increasing the driver
throughput by two-fold and reducing the possibility of -ENOBUFs.
Thus dynamically set the driver's max tx URBs value according
to firmware replies.

Device domains never span IOMMU hardware units, which allows the
domain ID space for each IOMMU to be an independent address space.
Therefore we can have multiple, independent domains, each with the
same domain->id, but attached to different hardware units. This is
also why we need to do a heavy-weight search for VM domains since
they can span multiple IOMMUs hardware units and we don't require a
single global ID to use for all hardware units.
Therefore, if we call iommu_detach_domain() across all active IOMMU
hardware units for a non-VM domain, the result is that we clear domain
IDs that are not associated with our domain, allowing them to be
re-allocated and causing apparent coherency issues when the device
cannot access IOVAs for the intended domain.
This bug was introduced in commit fb170fb4c548 ("iommu/vt-d: Introduce
helper functions to make code symmetric for readability"), but is
significantly exacerbated by the more recent commit 62c22167dd70
("iommu/vt-d: Fix dmar_domain leak in iommu_attach_device") which calls
domain_exit() more frequently to resolve a domain leak.

This patch is a fix to "iommu/arm-smmu: add support for iova_to_phys
through ATS1PR".
According to ARM documentation, translation registers are optional even
in SMMUv1, so ID0_S1TS needs to be checked to verify their presence.
Also, we check that the domain is a stage-1 domain.

Jan Kara pointed out that if there is an inode which is constantly
getting dirtied with I_DIRTY_PAGES, an inode with an updated timestamp
will never be written since inode->dirtied_when is constantly getting
updated. We fix this by adding an extra field to the inode,
dirtied_time_when, so inodes with a stale dirtytime can get detected
and handled.
In addition, if we have a dirtytime inode caused by an atime update,
and there is no write activity on the file system, we need to have a
secondary system to make sure these inodes get written out. We do
this by setting up a second delayed work structure which wakes up the
CPU much more rarely compared to writeback_expire_centisecs.

We currently have a problem that SELinux policy is being enforced when
creating debugfs files. If a debugfs file is created as a side effect of
doing some syscall, then that creation can fail if the SELinux policy
for that process prevents it.
This seems wrong. We don't do that for files under /proc, for instance,
so Bruce has proposed a patch to fix that.
While discussing that patch however, Greg K.H. stated:
"No kernel code should care / fail if a debugfs function fails, so
please fix up the sunrpc code first."
This patch converts all of the sunrpc debugfs setup code to be void
return functins, and the callers to not look for errors from those
functions.
This should allow rpc_clnt and rpc_xprt creation to work, even if the
kernel fails to create debugfs files for some reason.
Symptoms were failing krb5 mounts on systems using gss-proxy and
selinux.

alloc_init_open_stateowner can return an already freed entry if there is
a race to put openowners in the hashtable.
In commit 7ffb588086e9, we changed it so that we allocate and initialize
an openowner, and then check to see if a matching one got stuffed into
the hashtable in the meantime. If it did, then we free the one we just
allocated and take a reference on the one already there. There is a bug
here though. The code will then return the pointer to the one that was
allocated (and has now been freed).
This wasn't evident before as this race almost never occurred. The Linux
kernel client used to serialize requests for a single openowner. That
has changed now with v4.0 kernels, and this race can now easily occur.

locks_delete_lock_ctx() is called inside the loop, so we
should use list_for_each_entry_safe.
Fixes: 8634b51f6ca2 (locks: convert lease handling to file_lock_context)

Micron has released an updated firmware (MU02) for M510/M550/MX100
drives to fix the issues with queued TRIM. Queued TRIM remains broken on
M500 but is working fine on later drives such as M600 and MX200.
Tweak our blacklist to reflect the above.

Pull late GPIO fixes from Linus Walleij:
"Here are the (hopefully) last GPIO fixes for v4.0. Nothing
controversial whatsoever, just fixes:
- syscon GPIO fix for Keystone DSP GPIOs
- pin number translation fix for ACPI GPIO
- a smallish compiler warning fix on the mpc8xxx driver"

Now GPIO syscon driver produces bunch of warnings during the
boot of Kesytone 2 SoCs:
gpio-syscon soc:keystone_dsp_gpio@02620240: can't read the dir register offset!
gpio-syscon soc:keystone_dsp_gpio@2620244: can't read the dir register offset!
This message unintentionally was added using dev_err(), but its
actual log level is debug, because third cell of "ti,syscon-dev" is
optional.
Hence change it to dev_dbg() as it should be.
This patch fixes commit:

If GPIO driver use pin mapping, need to translate pin number
between ACPI table and GPIO driver.
This issue is found on one platform with Cherryview gpio
controller, kernel is hang when executed _PS0 method of
one ACPI device, since without this translation, it access
invalid gpiodesc array.
Verified it works again with this patch.

Pull ARM SoC fixes from Olof Johansson:
"The latest and greatest fixes for ARM platform code. Worth pointing
out are:
- Lines-wise, largest is a PXA fix for dealing with interrupts on DT
that was quite broken. It's still newish code so while we could
have held this off, it seemed appropriate to include now
- Some GPIO fixes for OMAP platforms added a few lines. This was
also fixes for code recently added (this release).
- Small OMAP timer fix to behave better with partially upstreamed
platforms, which is quite welcome.
- Allwinner fixes about operating point control, reducing
overclocking in some cases for better stability.
plus a handful of other smaller fixes across the map"

Without proper regulator support for individual boards, it is dangerous
to have overclocked/overvoltaged OPPs in the list. Cpufreq will increase
the frequency without the accompanying voltage increase, resulting in
an unstable system.
Remove them for now. We can revisit them with the new version of OPP
bindings, which support boost settings and frequency ranges, among
other things.
