ASoC: Updates for v4.9
Apart from the cleanups done by Morimoto-san this has very much been a
driver focused release with very little generic change:
- A big factoring out of the simple-card code to allow it to be shared
more with the rcar generic card from Kuninori Morimoto.
- Removal of some operations duplicated on the CODEC level, again by
Kuninori Morimoto.
- Lots more machine support for x86 systems.
- New drivers for Nuvoton NAU88C10, Realtek RT5660 and RT5663.

ASoC: tlv320aic31xx: add explicit support for tlv320dac31xx
tlv320dac31xx is a subset of tlv320aic31xx:
- it does not have MIC inputs and ADC, thus capture is not supported,
- it has analog inputs AIN1/AIN2 that can be mixed into output.
Although tlv320dac31xx does work with tlv320aic31xx driver, this setup
does register non-existent widgets and non-existent capture stream.
Thus userspace lists non-existent objects in user interfaces, an can
access these, causing operations with device registers that are
declared as "reserved" in tlv320dac31xx datasheet.
This patch fixes this situation by separating controls/widgets/routes
into common, aic31xx-specific, and dac31xx-specific parts. Only parts
that match actual hardware (as declared in "compatible" device tree
property) are registered.

mm: check VMA flags to avoid invalid PROT_NONE NUMA balancing
The NUMA balancing logic uses an arch-specific PROT_NONE page table flag
defined by pte_protnone() or pmd_protnone() to mark PTEs or huge page
PMDs respectively as requiring balancing upon a subsequent page fault.
User-defined PROT_NONE memory regions which also have this flag set will
not normally invoke the NUMA balancing code as do_page_fault() will send
a segfault to the process before handle_mm_fault() is even called.
However if access_remote_vm() is invoked to access a PROT_NONE region of
memory, handle_mm_fault() is called via faultin_page() and
__get_user_pages() without any access checks being performed, meaning
the NUMA balancing logic is incorrectly invoked on a non-NUMA memory
region.
A simple means of triggering this problem is to access PROT_NONE mmap'd
memory using /proc/self/mem which reliably results in the NUMA handling
functions being invoked when CONFIG_NUMA_BALANCING is set.
This issue was reported in bugzilla (issue 99101) which includes some
simple repro code.
There are BUG_ON() checks in do_numa_page() and do_huge_pmd_numa_page()
added at commit c0e7cad to avoid accidentally provoking strange
behaviour by attempting to apply NUMA balancing to pages that are in
fact PROT_NONE. The BUG_ON()'s are consistently triggered by the repro.
This patch moves the PROT_NONE check into mm/memory.c rather than
invoking BUG_ON() as faulting in these pages via faultin_page() is a
valid reason for reaching the NUMA check with the PROT_NONE page table
flag set and is therefore not always a bug.

radix tree: fix sibling entry handling in radix_tree_descend()
The fixes to the radix tree test suite show that the multi-order case is
broken. The basic reason is that the radix tree code uses tagged
pointers with the "internal" bit in the low bits, and calculating the
pointer indices was supposed to mask off those bits. But gcc will
notice that we then use the index to re-create the pointer, and will
avoid doing the arithmetic and use the tagged pointer directly.
This cleans the code up, using the existing is_sibling_entry() helper to
validate the sibling pointer range (instead of open-coding it), and
using entry_to_node() to mask off the low tag bit from the pointer. And
once you do that, you might as well just use the now cleaned-up pointer
directly.
[ Side note: the multi-order code isn't actually ever used in the kernel
right now, and the only reason I didn't just delete all that code is
that Kirill Shutemov piped up and said:
"Well, my ext4-with-huge-pages patchset[1] uses multi-order entries.
It also converts shmem-with-huge-pages and hugetlb to them.
I'm okay with converting it to other mechanism, but I need
something. (I looked into Konstantin's RFC patchset[2]. It looks
okay, but I don't feel myself qualified to review it as I don't
know much about radix-tree internals.)"

having to count the items manually for TLV_DB_RANGE_HEAD()". In short,
TLV_DB_RANGE_HEAD macro was obsoleted.
In commit 46e860f76804 ("ALSA: rename TLV-related macros so that they're
friendly to user applications"), TLV-related macros are exposed for
applications in user land to get content of data structured by
Type/Length/Value shape. The commit managed to expose TLV-related macros
as many as possible, while obsoleted TLV_DB_RANGE_HEAD() was included to
the list of exposed macros.
This situation brings some confusions to application developers because
they might think all exposed macros have their own purpose and useful for
applications.
For the reason, this commit moves TLV_DB_RANGE_HEAD macro from UAPI header
to a header for kernel land, again. The above commit is done within the
same development period for kernel 4.9, thus not published yet. This
commit might certainly brings no confusions to user land.

MIPS: SMP: Fix possibility of deadlock when bringing CPUs online
This patch fixes the possibility of a deadlock when bringing up

The deadlock occurs because the set_cpu_online() is called before
synchronise_count_slave(). This can cause a deadlock if the boot CPU,
having scheduled another thread, attempts to send an IPI to the
secondary CPU, which it sees has been marked online. The secondary is
blocked in synchronise_count_slave() waiting for the boot CPU to enter
synchronise_count_master(), but the boot cpu is blocked in
smp_call_function_many() waiting for the secondary to respond to it's
IPI request.
Fix this by marking the CPU online in cpu_callin_map and synchronising
counters before declaring the CPU online and calculating the maps for
IPIs.

ASoC: exynos: organize the asoc audio into a menu
It is simple sound card time, we could assign different codec
to a interface without making a specific driver for it. The SPDIF
and I2S interface for Samsung would be possible used by
simple-sound-card, but not sure about the PCM.
Those S3C time entries are left alone as I don't think any new board
would need them.

ASoC: wm_adsp: Make DSP preloader a supply widget
Currently the DSP loading is split into two widgets, the preloader that
is a snd_soc_dapm_dai_link widget which starts a thread to download
the firmware, and the DSP itself which is a snd_soc_dapm_out_drv and
synchronises the thread back in to the DAPM sequence. This allows the
firmware download to be overlapped with the rest of the path bring up.
The use of a snd_soc_dapm_dai_link widget requires the preloader to be part
of the audio path in DAPM, really a supply widget is a better fit for the
preloader. The preloader is something that needs to be done for the DSP to
function, not a part of the audio path itself.
This change makes the DSP preloader widget a supply widget, which as well
as probably being a better fit will also make it much simpler to power up
the preloader widget to trigger firmware download to the core independently
of the audio path coming up.

ASoC: arizona: Attach SYSCLK to DSP preloaders
Currently SYSCLK is attached to every compressed DAI as this follows the
pattern of attaching clocks to the chips inputs and outputs, however, it is
really the DSP that requires the clock here. As firmware download can be a
significant part of the path startup time for these devices occasionally it
would be desirable to download the firmware in advance of the path being
brought up.
To help facilitate this early firmware loading this patch attaches the
SYSCLK to the DSP preloader widget. This also saves us adding a new route
to SYSCLK every time a new compressed DAI is created.

ASoC: wm_adsp: Move control cache sync out of preloader
As part of the work to download firmware before the audio path is brought
up the DSP will be put into a low power state between downloading firmware
to the core and starting it running. This will mean that the firmware ALSA
controls are not accessible in the hardware during this period of time.
To prepare for this change we gate access to the hardware in the ALSA
control handlers on the DSP being running rather than simply booted and
move the synchronisation of the control caches out of the preloader delayed
work and into the main DAPM thread after the DSP will have been brought out
of its low power state.

ASoC: wm_adsp: Separate concept of booted and running
Currently the wm_adsp driver has a flag that indicates the DSP is
"running", this flag is used to gate access to the hardware. However this
flag is actually set in the firmware download thread after the firmware has
been downloaded, but this is before the core is actually started running,
so really it currently indicates that the core has been booted and is
perhaps running.
This patch clearly separates out the concepts of booted (firmware is
downloaded) and running (code is executing on the DSP) within the wm_adsp
driver.

Merge branch 'hughd-fixes' (patches from Hugh Dickins)
Merge VM fixes from High Dickins:
"I get the impression that Andrew is away or busy at the moment, so I'm
going to send you three independent uncontroversial little mm fixes
directly - though none is strictly a 4.8 regression fix.
- shmem: fix tmpfs to handle the huge= option properly from Toshi
Kani is a one-liner to fix a major embarrassment in 4.8's hugepages
on tmpfs feature: although Hillf pointed it out in June, somehow
both Kirill and I repeatedly dropped the ball on this one. You
might wonder if the feature got tested at all with that bug in:
yes, it did, but for wider testing coverage, Kirill and I had each
relied too much on an override which bypasses that condition.
- huge tmpfs: fix Committed_AS leak just a run-of-the-mill accounting
fix in the same feature.
- mm: delete unnecessary and unsafe init_tlb_ubc() is an unrelated
fix to 4.3's TLB flush batching in reclaim: the bug would be rare,
and none of us will be shamed if this one misses 4.8; but it got
such a quick ack from Mel today that I'm inclined to offer it along
with the first two"

ASoC: tpa6130a2: fix volume setting when no stream is running
After moving tpa6130a2 power management to DAPM, if chip can be physically
powered off (either reset_gpio is defined, or regulator indeed removes
power), then volume change no longer works unless chip is on due to
a running stream.
Fix that by entering regcache cache_only mode while chip is off.
Move regcache calls to tpa6130a2_power() to get them at driver init time
as well.

ASoC: Intel: Skylake: Add module instance id generation APIs
Driver needs to send unique module instance id to firmware while
creating the module and uses this id to communicate with DSP for setting

But, we have upper bound of instance ID. The current IDs are coming from
topology but it doesn't know the upper bound and can't assign unique
id's subject to upper bounds as we can create a big graph but not all
parts running at same time.
This patch adds a 128bit unique id management routines which are built
on top of ffz() for faster implementation. Unfortunately ffz() works on
32bits values, so additional code is added on top of ffz() to create a
128bit unique id.

init_tlb_ubc() looked unnecessary to me: tlb_ubc is statically
initialized with zeroes in the init_task, and copied from parent to
child while it is quiescent in arch_dup_task_struct(); so I went to
delete it.
But inserted temporary debug WARN_ONs in place of init_tlb_ubc() to
check that it was always empty at that point, and found them firing:
because memcg reclaim can recurse into global reclaim (when allocating
biosets for swapout in my case), and arrive back at the init_tlb_ubc()
in shrink_node_memcg().
Resetting tlb_ubc.flush_required at that point is wrong: if the upper
level needs a deferred TLB flush, but the lower level turns out not to,
we miss a TLB flush. But fortunately, that's the only part of the
protocol that does not nest: with the initialization removed, cpumask
collects bits from upper and lower levels, and flushes TLB when needed.
