In the former case, the reason is that virmidi has an open code
calling snd_rawmidi_transmit_ack() with the value calculated outside
the spinlock. We may use snd_rawmidi_transmit() in a loop just for
consuming the input data, but even there, there is a race between
snd_rawmidi_transmit_peek() and snd_rawmidi_tranmit_ack().
Similarly in the latter case, it calls snd_rawmidi_transmit_peek() and
snd_rawmidi_tranmit_ack() separately without protection, so they are
racy as well.
The patch tries to address these issues by the following ways:
- Introduce the unlocked versions of snd_rawmidi_transmit_peek() and
snd_rawmidi_transmit_ack() to be called inside the explicit lock.
- Rewrite snd_rawmidi_transmit() to be race-free (the former case).
- Make the split calls (the latter case) protected in the rawmidi spin
lock.

Mac Mini 7,1 model with CS4208 codec reports the headphone jack
detection wrongly in an inverted way. Moreover, the advertised pins
for the audio input and SPDIF output have actually no jack detection.
This patch addresses these issues. The inv_jack_detect flag is set
for fixing the headphone jack detection, and the pin configs for audio
input and SPDIF output are marked as non-detectable.

The only remaining caller of genpd_poweron() is conditionally compiled
based on CONFIG_PM_GENERIC_DOMAINS_OF, so we get a warning when that is
unset.
By moving the locking/unlocking of the genpd outside genpd_poweron(), thus
to the caller, genpd_poweron() becomes redundant.
Within this context let's then rename the wrapper function,
__genpd_poweron(), to genpd_poweron() as it will then be consistent with
its friend genpd_poweroff().
This change silence the warning about the unused function.

ALSA timer core framework has no sync point at stopping because it's
called inside the spinlock. Thus we need a sync point at close for
avoiding the stray timer task. This is simply done by implementing
the close callback just calling del_timer_sync(). (It's harmless to
call it unconditionally, as the core timer itself cares of the already
deleted timer instance.)

futex.h's futex_atomic_cmpxchg_inatomic() does not use the
__futex_atomic_op() macro and needs its own PAN toggling. This was missed
when the feature was implemented.

The range of set_memory_* is currently restricted to the module address
range because of difficulties in breaking down larger block sizes.
vmalloc maps PAGE_SIZE pages so it is safe to use as well. Update the
function ranges and add a comment explaining why the range is restricted
the way it is.

The interrupts for EDID_READY or DDC_ERROR were never enabled in this
driver, so reading EDID always timed out when chip was powered down and
interrupts were used. Fix this and also remove clearing the interrupt
flags, they are cleared in POWER_DOWN mode anyhow (unlike the interrupt
enable flags) according to docs and my tests.

This patch fixes the calculation of pcc_chan for non-zero id.
After the compiler ignores the (unsigned long) cast the
pcc_mbox_channels pointer is type-cast and then the type-cast
offset is added which results in address outside of the range
leading to the kernel crashing.
We might add braces and make it:
pcc_chan = (struct mbox_chan *)
((unsigned long) pcc_mbox_channels +
(id * sizeof(*pcc_chan)));
but let's go with array approach here and use id as index.

assembly fixes, the other things are mostly board related:

which is bad. The fix in most cases is to load the value from data
section using a pointer. Let's also enable ARM_KERNMEM_PERMS so
DEBUG_RODATA gets selected by default. And while testing things,
I also added few more loadable driver modules to the defconfig that
I seem to need quite often.
- Fix a long standing omap5 RTC mystery and enable RTC where we need
to ensure the SoC msecure pin is high so we can write to the RTC

- Fix irq types for am437x
- A series of minor dts fixes for sbc-am57x and cl-som-am57x
- Fixes for torpedo dts to make WLAN behave and to remove a duplicate

This series also includes few minor changes that are not stricly
fixes, but would be good to get in during the early -rc cycle:
- Remove legacy mailbox platform data that is no longer needed
- Add the pdata-quirks needed for the new pwm-omap-dmtimer so

- Enable ti,mbox-send-noirq that's needed by wkup_m3 driver
