multicast filtering from Alex, set_tim debouncing from Ilan,
per-interface debugfs cleanups from Stanislaw, an error return fix from

And for the iwlwifi bits, Johannes says:
"Andrei changed an instance of kmalloc+memdup to kmemdup, Stanislaw
removed the now unused 5ghz_disable module parameter. I also have a
number of fixes from Ilan, Emmanuel and myself, Emmanuel also continued
working on Bluetooth coexistence."
For the sizeable batch of Bluetooth bits, Gustavo says:
"This is our first batch of patches for 3.10. The biggest changes of this pull
request are from Johan Hedberg, he implemented a HCI request framework to make
life easier when we have to send many HCI commands and a block and wait for
all of the to finish, we were able to fix a few issues in stack with the
introduction of this framework.
Other than that Dean Jenkins did a good work cleaning the RFCOMM code, the
refcnt infrastructure was removed and now we use NULL pointer checks to know
when a object was freed or not. That code was buggy and now it looks a way
better.
The rest of changes are clean ups, fixes and small improvements all over the
Bluetooth subsystem."
Regarding the wl12xx bits, Luca says:
"Some patches intended for 3.10. Mostly bug fixes and other small
improvements."
On top of that, there are updates to brcmfmac, brcmsmac, b43, ssb and
bcma, as well as mwifiex, rt2x00, and ath9k and a few others. The most
notable bit is the addition of a new driver in the rtlwifi family.

If authentication (or association with FT) is requested by
userspace, mac80211 currently doesn't tell cfg80211 that it
disconnected from the AP. That leaves inconsistent state:
cfg80211 thinks it's connected while mac80211 thinks it's
not. Typically this won't last long, as soon as mac80211
reports the new association to cfg80211 the old one goes
away. If, however, the new authentication or association
doesn't succeed, then cfg80211 will forever think the old
one still exists and will refuse attempts to authenticate
or associate with the AP it thinks it's connected to.
Anders reported that this leads to it taking a very long
time to reconnect to a network, or never even succeeding.
I tested this with an AP hacked to never respond to auth
frames, and one that works, and with just those two the
system never recovers because one won't work and cfg80211
thinks it's connected to the other so refuses connections
to it.
To fix this, simply make mac80211 tell cfg80211 when it is
no longer connected to the old AP, while authenticating or
associating to a new one.

The cnic module is responsible for initializing various bnx2x structs
via callbacks provided by the bnx2x module.
One such struct is the queue object for the FCoE queue.
If a device is working in AFEX mode and its configuration allows FCoE yet
the cnic module is not loaded, it's very likely a null pointer dereference
will occur, as the bnx2x will erroneously access the FCoE's queue object.
Prevent said access until cnic properly registers itself.

Invoking arch_flush_lazy_mmu_mode() results in calls to

Since lazy MMU is not used on bare metal we can patch away
arch_flush_lazy_mmu_mode() so that it is never called in such
environment.

Cc: <stable@vger.kernel.org> SEE NOTE ABOVE
In paravirtualized x86_64 kernels, vmalloc_fault may cause an oops
when lazy MMU updates are enabled, because set_pgd effects are being
deferred.
One instance of this problem is during process mm cleanup with memory
cgroups enabled. The chain of events is as follows:
- zap_pte_range enables lazy MMU updates
- zap_pte_range eventually calls mem_cgroup_charge_statistics,
which accesses the vmalloc'd mem_cgroup per-cpu stat area
- vmalloc_fault is triggered which tries to sync the corresponding
PGD entry with set_pgd, but the update is deferred
- vmalloc_fault oopses due to a mismatch in the PUD entries
The OOPs usually looks as so:

If AR_CRCErr, AR_PHYErr, AR_DecryptCRCErr or AR_MichaelErr is indicated
in the rx status word, but AR_RxFrameOK is also set, the descriptor
contents are typically invalid. This can show up as a warning about
invalid MCS rates in a frame. Even with those checks in place, a
descriptor with invalid MCS rates can still sometimes make it through to
the driver (mostly on older hardware like AR91xx).
Detect such errors in the last descriptor of a frame and discard the
whole frame if present.

As the comment in ath_get_next_rx_buf indicates, if a descriptor with
the done bit set follows one with the done bit cleared, both descriptors
should be discarded, however the driver is not doing that yet.
To fix this, use the rs->rs_more flag as an indicator that the following
frame should be discarded. This also helps with the split buffer case:
if the first part of the frame is discarded, the following parts need to
be discarded as well, since they contain no valid header or usable data.

The functions in the rt2x00mmio module has been
moved from the rt2x00pci module. Each function
uses the rt2x00pci prefix which is a bit confusing.
Use the r2x000mmio prefix for each function to make
it consistent with the module name.
The renamed functions are used by several modules,
and updating the names in all of them would result
in a big patch. In order to keep the patch simple,
add compatibility defines for the old function
names. This allows to update the names in each
module separately. After each module is updated,
the defines can be removed.

"I suddenly noticed that a one-line issue that I _thought_ I had fixed
with the nfs41_walk_client_list patch was apparently still there in
the pull request I sent earlier today. I'm very sorry for not
catching that in time.

NFSv4: Doh! Typo in the fix to nfs41_walk_client_list
This patch fix the regression introduced by the commit 3202bf0157
"arm: mvebu: Improve the SMP support of the interrupt controller":
GPIO IRQ were no longer delivered to the CPUs.
To be delivered to a CPU an interrupt must be enabled at CPU level and
at interrupt source level. Before the offending patch, all the
interrupts were enabled at source level during map() function. Mask()
and unmask() was done by handling the per-CPU part. It was fine when
running in UP with only one CPU.
The offending patch added support for SMP, in this case mask() and
unmask() was done by handling the interrupt source level part. The
per-CPU level part was handled by the affinity API to select the CPU
which will receive the interrupt. (Due to some hardware limitation
only one CPU at a time can received a given interrupt).
For "normal" interrupt __setup_irq() was called when an irq was
registered. irq_set_affinity() is called from this function, which
enabled the interrupt on one of the CPUs. Whereas for GPIO IRQ which
were chained interrupts, the irq_set_affinity() was never called and
none of the CPUs was selected to receive the interrupt.
With this patch all the interrupt are enable on the current CPU during
map() function. Enabling the interrupts on a CPU doesn't depend
anymore on irq_set_affinity() and then the chained irq are not anymore
a special case. However the CPU which will receive the irq can still
be modify later using irq_set_affinity().
Tested with Mirabox (A370) and Openblocks AX3 (AXP), rootfs mounted
over NFS, compiled with CONFIG_SMP=y/N.

Make sure that we set the status to 0 on success. Missed in testing
because it never appears when doing multiple mounts to _different_
servers.
