John W. Linville says:
====================
This is one more set of fixes intended for the 3.11 stream...
For the mac80211 bits, Johannes says:
"I have three more patches for the 3.11 stream: Felix's fix for the
fairly visible brcmsmac crash, a fix from Simon for an IBSS join bug I
found and a fix for a channel context bug in IBSS I'd introduced."
Along with those...
Sujith Manoharan makes a minor change to not use a PLL hang workaroun
for AR9550. This one-liner fixes a couple of bugs reported in the Red Hat
bugzilla.
Helmut Schaa addresses an ath9k_htc bug that mangles frame headers
during Tx. This fix is small, tested by the bug reported and isolated
to ath9k_htc.
Stanislaw Gruszka reverts a recent iwl4965 change that broke rfkill
notification to user space.
Please let me know if there are problems!

drivers/platform/olpc/olpc-ec.c: initialise earlier
|
|
Being a low-level component, various drivers (e.g. olpc-battery) assume
that it is ok to communicate with the OLPC Embedded Controller during
probe. Therefore the OLPC EC driver must be initialised before other
drivers try to use it. This was the case until it was recently moved
out of arch/x86 and restructured around commits ac2504151f5a ("Platform:
OLPC: turn EC driver into a platform_driver") and 85f90cf6ca56 ("x86:
OLPC: switch over to using new EC driver on x86").
Use arch_initcall so that olpc-ec is readied earlier, matching the
previous behaviour.
Fixes a regression introduced in Linux-3.6 where various drivers such as
olpc-battery and olpc-xo1-sci failed to load due to an inability to
communicate with the EC. The user-visible effect was a lack of battery
monitoring, missing ebook/lid switch input devices, etc.

The PLL hang workaround is required only for AR9330 and

is enabled for AR9340 also (DB120 etc.), since it uses a PLL
design identical to AR9330. This is not required for AR9485 and AR9550.

ath9k_htc adds padding between the 802.11 header and the payload during
TX by moving the header. When handing the frame back to mac80211 for TX
status handling the header is not moved back into its original position.
This can result in a too small skb headroom when entering ath9k_htc
again (due to a soft retransmission for example) causing an
skb_under_panic oops.
Fix this by moving the 802.11 header back into its original position
before returning the frame to mac80211 as other drivers like rt2x00
or ath5k do.

Already existing property flags are filled wrong for properties created from
initial FDT. This could cause problems if this DYNAMIC device-tree functions
are used later, i.e. properties are attached/detached/replaced. Simply dumping
flags from the running system show, that some initial static (not allocated via
kzmalloc()) nodes are marked as dynamic.
I putted some debug extensions to property_proc_show(..) :
..
+ if (OF_IS_DYNAMIC(pp))
+ pr_err("DEBUG: xxx : OF_IS_DYNAMIC\n");
+ if (OF_IS_DETACHED(pp))
+ pr_err("DEBUG: xxx : OF_IS_DETACHED\n");
when you operate on the nodes (e.g.: ~$ cat /proc/device-tree/*some_node*) you
will see that those flags are filled wrong, basically in most cases it will dump
a DYNAMIC or DETACHED status, which is in not true.
(BTW. this OF_IS_DETACHED is a own define for debug purposes which which just
make a test_bit(OF_DETACHED, &x->_flags)
If nodes are dynamic kernel is allowed to kfree() them. But it will crash
attempting to do so on the nodes from FDT -- they are not allocated via
kzmalloc().

libertas driver."
Along with the above...

but probe (via_init_one()) returns zero. That can lead to null pointer dereference

When a event is being bound to a VCPU there is a window between the
EVTCHNOP_bind_vpcu call and the adjustment of the local per-cpu masks
where an event may be lost. The hypervisor upcalls the new VCPU but
the kernel thinks that event is still bound to the old VCPU and
ignores it.
There is even a problem when the event is being bound to the same VCPU
as there is a small window beween the clear_bit() and set_bit() calls
in bind_evtchn_to_cpu(). When scanning for pending events, the kernel
may read the bit when it is momentarily clear and ignore the event.
Avoid this by masking the event during the whole bind operation.

The sizeof() argument in init_evtchn_cpu_bindings() is incorrect
resulting in only the first 64 (or 32 in 32-bit guests) ports having
their bindings being initialized to VCPU 0.
In most cases this does not cause a problem as request_irq() will set
the irq affinity which will set the correct local per-cpu mask.
However, if the request_irq() is called on a VCPU other than 0, there
is a window between the unmasking of the event and the affinity being
set were an event may be lost because it is not locally unmasked on
any VCPU. If request_irq() is called on VCPU 0 then local irqs are
disabled during the window and the race does not occur.
Fix this by initializing all NR_EVENT_CHANNEL bits in the local
per-cpu masks.

There are possible HW configurations in which PFs will have SR-IOV capability
but will have Max VFs set to 0 - this happens when there are Multi-Function
devices where the VFs are allocated to only some of the PFs.
DMAE is configured to support VFs only if the configuring PF has supported VFs.
In case the first PF to be loaded will be one without supported VFs, it will
not configure DMAE to the VF-supporting mode. When VFs of other PFs will be
loaded later on, they will not be able to communicate with their PF.
This changes the requirement for configuring DMAE for VF-supporting mode;
If the device has SR-IOV capabilities there must be some PF that has
max supported VFs > 0, thus it will configure the DMAE for supporting VFs.

asynchronously, the various callbacks need a robust sanity check before
attempting to access the SR-IOV database and members since there are numerous

After notification that DCBX configuration has ended arrived to the driver,
the driver configured the FW/HW in sleepless context.
As a result, it was possible to reach a race (mostly with CNIC registration)
in which the configuration will return a timeout, failing to set the DCBX
results correctly.
This patch moves the configuration following the DCBX end into the slowpath

drm/i915: Don't deref pipe->cpu_transcoder in the hangcheck code
|

This fixes a WARN in i915_gem_free_object when the
obj->pages_pin_count isn't 0.
v2: Add locking to unmap, noticed by Chris Wilson. Note that even
though we call unmap with our own dev->struct_mutex held that won't
result in an immediate deadlock since we never go through the dma_buf
interfaces for our own, reimported buffers. But it's still easy to
blow up and anger lockdep, but that's already the case with our ->map
implementation. Fixing this for real will involve per dma-buf ww mutex
locking by the callers. And lots of fun. So go with the duct-tape
approach for now.

On sparc32, which includes <linux/swap.h> from <asm/pgtable_32.h>:
drivers/md/dm-cache-policy-mq.c:962:13: error: conflicting types for 'remove_mapping'
include/linux/swap.h:285:12: note: previous declaration of 'remove_mapping' was here
As mq_remove_mapping() already exists, and the local remove_mapping() is
used only once, inline it manually to avoid the conflict.
