cc05fcc4b0 ARM: OMAP: rx51: change musb mode to OTG
Peripheral-only mode got broken in v3.11-rc1 because of unknown reasons.
Change the mode to OTG, in practice that should work equally well even
when/if the regression gets fixed.

Note that the peripheral-only regression is a separate patch, this change
is still correct as the role is handled by hardware.

Commit b7e2e75a8c ("usb: gadget: drop unused USB_GADGET_MUSB_HDRC")
dropped a config symbol that was unused by the musb core, but it turns
out that board support code still had references to it.

As the core now handles both dual role and host-only modes, we can just
pass MUSB_OTG as mode from board files.

869c6a3ede i2c: mxs: fix broken timing calculation
The timing calculation is rather bogus and gives extremely wrong
results for higher frequencies (on an i.MX28). E.g. instead of 400 kHz
I measured 770 kHz.

Implement a calculation that adheres to the I2C spec and gives exact
results for I2C frequencies from 12.56 kHz to 960 kHz.

Also the bus_free and leadin parameters are programmed according to
the I2C spec for standard and fast mode.

This was tested on a Ka-Ro TX28 module with a DS1339, TSC2007, PCA9554
and SGTL5000 client.

948b26b6dd perf: Account freq events globally
Freq events may not always be affine to a particular CPU. As such,
account_event_cpu() may crash if we account per cpu a freq event
that has event->cpu == -1.

To solve this, lets account freq events globally. In practice
this doesn't change much the picture because perf tools create
per-task perf events with one event per CPU by default. Profiling a
single CPU is usually a corner case so there is no much point in
optimizing things that way.

fc3b86d673 perf: Roll back callchain buffer refcount under the callchain mutex
When we fail to allocate the callchain buffers, we roll back the refcount
we did and return from get_callchain_buffers().

However we take the refcount and allocate under the callchain lock
but the rollback is done outside the lock.

As a result, while we roll back, some concurrent callchain user may
call get_callchain_buffers(), see the non-zero refcount and give up
because the buffers are NULL without itself retrying the allocation.

The consequences aren't that bad but that behaviour looks weird enough and
it's better to give their chances to the following callchain users where
we failed.

c2e7fcf53c nohz: Include local CPU in full dynticks global kick
tick_nohz_full_kick_all() is useful to notify all full dynticks
CPUs that there is a system state change to checkout before
re-evaluating the need for the tick.

Unfortunately this is implemented using smp_call_function_many()
that ignores the local CPU. This CPU also needs to re-evaluate
the tick.

on_each_cpu_mask() is not useful either because we don't want to
re-evaluate the tick state in place but asynchronously from an IPI
to avoid messing up with any random locking scenario.

So lets call tick_nohz_full_kick() from tick_nohz_full_kick_all()
so that the usual irq work takes care of it.

2b047252d0 Fix TLB gather virtual address range invalidation corner cases
Ben Tebulin reported:

 "Since v3.7.2 on two independent machines a very specific Git
  repository fails in 9/10 cases on git-fsck due to an SHA1/memory
  failures.  This only occurs on a very specific repository and can be
  reproduced stably on two independent laptops.  Git mailing list ran
  out of ideas and for me this looks like some very exotic kernel issue"

and bisected the failure to the backport of commit 53a59fc67f ("mm:
limit mmu_gather batching to fix soft lockups on !CONFIG_PREEMPT").

That commit itself is not actually buggy, but what it does is to make it
much more likely to hit the partial TLB invalidation case, since it
introduces a new case in tlb_next_batch() that previously only ever
happened when running out of memory.

The real bug is that the TLB gather virtual memory range setup is subtly
buggered.  It was introduced in commit 597e1c3580 ("mm/mmu_gather:
enable tlb flush range in generic mmu_gather"), and the range handling
was already fixed at least once in commit e6c495a96c ("mm: fix the TLB
range flushed when __tlb_remove_page() runs out of slots"), but that fix
was not complete.

The problem with the TLB gather virtual address range is that it isn't
set up by the initial tlb_gather_mmu() initialization (which didn't get
the TLB range information), but it is set up ad-hoc later by the
functions that actually flush the TLB.  And so any such case that forgot
to update the TLB range entries would potentially miss TLB invalidates.

Rather than try to figure out exactly which particular ad-hoc range
setup was missing (I personally suspect it's the hugetlb case in
zap_huge_pmd(), which didn't have the same logic as zap_pte_range()
did), this patch just gets rid of the problem at the source: make the
TLB range information available to tlb_gather_mmu(), and initialize it
when initializing all the other tlb gather fields.

This makes the patch larger, but conceptually much simpler.  And the end
result is much more understandable; even if you want to play games with
partial ranges when invalidating the TLB contents in chunks, now the
range information is always there, and anybody who doesn't want to
bother with it won't introduce subtle bugs.

Ben verified that this fixes his problem.

If doms_new is NULL, partition_sched_domains() will reset ndoms_cur
to 0, and free old sched domains with free_sched_domains(doms_cur, ndoms_cur).
As ndoms_cur is 0, the cpumask will not be freed.

40a625daa8 gpio: pca953x: fix gpio input on gpio offsets >= 8
This change fixes a regression introduced by commit
f5f0b7aa8 (gpio: pca953x: make the register access by GPIO bank)

When the pca953x driver was converted to using 8-bit reads/writes
the bitmask in pca953x_gpio_get_value wasn't adjusted with a
modulus BANK_SZ and consequently looks at the wrong bits in the
input register.

08a67a58af drivers/gpio: simplify use of devm_ioremap_resource
Remove unneeded error handling on the result of a call to
platform_get_resource when the value is passed to devm_ioremap_resource.

Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more clear.

27b3eb9c06 mac80211: add APIs to allow keeping connections after WoWLAN
In order to be able to (securely) keep connections alive after
the system was suspended for WoWLAN, we need some additional
APIs. We already have API (ieee80211_gtk_rekey_notify) to tell
wpa_supplicant about the new replay counter if GTK rekeying
was done by the device while the host was asleep, but that's
not sufficient.

If GTK rekeying wasn't done, we need to tell the host about
sequence counters for the GTK (and PTK regardless of rekeying)
that was used while asleep, add ieee80211_set_key_rx_seq() for
that.

If GTK rekeying was done, then we need to be able to disable
the old keys (with ieee80211_remove_key()) and allocate the
new GTK key(s) in mac80211 (with ieee80211_gtk_rekey_add()).

If protocol offload (e.g. ARP) is implemented, then also the
TX sequence counter for the PTK must be updated, using the new
ieee80211_set_key_tx_seq() function.

the decryption failed for some reason, the stack used to not process
the PM and MOREDATA bits for that frame. The stack now always performs

encrypted data frames and NULLFUNC frames are now handled in the same way
