Pull power management and ACPI fixes from Rafael Wysocki:
"These are four fixes for bugs in the devfreq and cpufreq subsystems,
including two regression fixes (one for a recent regression and one
for a problem introduced in 4.2).
Specifics:
- Two fixes for cpufreq regressions, an acpi-cpufreq driver one
introduced during the 4.2 cycle when we started to preserve cpufreq
directories for offline CPUs and a general one introduced recently
(Srinivas Pandruvada).
- Two devfreq fixes, one for a double kfree() in an error code path
and one for a confusing sysfs-related failure (Geliang Tang, Tobias
Jakobi)"

When handling device GET_DESCRIPTOR, composite gadget driver fills
the bcdUSB field only if the gadget supports USB 3.0. Otherwise
the field is left unfilled.
For consistency, set bcdUSB to 0x0200 for gadgets that don't
support superspeed.
It's correct to use 0x0200 for any setting that doesn't use
superspeed, since USB 2.0 devices can restrict themselves to
full speed only. It is NOT correct to use 0x0210, since BOS
descriptors are handled only if gadget_is_superspeed() is
satisfied, otherwise it results in a stall.

Now that it is possible to build in multiple dma engines, we can no longer
require MUSB_PIO_ONLY to be set when using the sunxi musb glue.
This patch adds dummy dma hooks to make the musb glue work without
MUSB_PIO_ONLY. This hooks are fake because we do not support dma with
musb on sunxi. The Allwinnner Android kernels have some dma code, but it
is disabled as Allwinner never managed to get it to work.

This patch allows the dwc3 driver to run on the new Synopsys USB 3.1
IP core, albeit in USB 3.0 mode only.
The Synopsys USB 3.1 IP (DWC_usb31) retains mostly the same register
interface and programming model as the existing USB 3.0 controller IP
(DWC_usb3). However the GSNPSID and version numbers are different.
Add checking for the new ID to pass driver probe.
Also, since the DWC_usb31 version number is lower in value than the
full GSNPSID of the DWC_usb3 IP, we set the high bit to identify
DWC_usb31 and to ensure the values are higher.
Finally, add a documentation note about the revision numbering scheme.
Any future revision checks (for STARS, workarounds, and new features)
should take into consideration how it applies to both the 3.1/3.0 IP.

Commit 76c44f6d80 introduced the possibly for "Overflow" to be reported
by the snapshot device's status. Older userspace (e.g. lvm2) does not
handle the "Overflow" status response.
Fix this incompatibility by requiring newer userspace code, that can
cope with "Overflow", request the persistent store with overflow support
by using "PO" (Persistent with Overflow) for the snapshot store type.

The cleaner policy doesn't make use of the per cache block hint space in
the metadata (unlike the other policies). When switching from the
cleaner policy to mq or smq a NULL pointer crash (in dm_tm_new_block)
was observed. The crash was caused by bugs in dm-cache-metadata.c
when trying to skip creation of the hint btree.
The minimal fix is to change hint size for the cleaner policy to 4 bytes
(only hint size supported).

The commit 55ce74d4bfe1b9444436264c637f39a152d1e5ac (md/raid1: ensure
device failure recorded before write request returns) is causing crash in
the LVM2 testsuite test shell/lvchange-raid.sh. For me the crash is 100%
reproducible.
The reason for the crash is that the newly added code in raid1d moves the
list from conf->bio_end_io_list to tmp, then tests if tmp is non-empty and
then incorrectly pops the bio from conf->bio_end_io_list (which is empty
because the list was alrady moved).
Raid-10 has a similar bug.

The Atmel sdhci device needs a new quirk. sdhci_set_clock set the Clock
Control Register to 0 before computing the new value and writing it.
It disables the internal clock which causes a reset mecanism. If we
write the new value before this reset mecanism is done, it will prevent
the stabilisation of the internal clock, so a delay is needed. This
delay is about 2-3 cycles of the base clock. To be safe, a 1 ms delay is
used.

shci-pxav3 driver is enabling by default the
SDHCI_QUIRK_CAP_CLOCK_BASE_BROKEN quirk. However this quirk is not
required for Armada 38x and leads to wrong clock setting in the divider.

Starting with commit 7d607f917008 ("mmc: host: omap_hsmmc: use
devm_regulator_get_optional() for vmmc") MMC on omap3 stopped working
for legacy booting.
This is because legacy booting sets up some of the resource in the
platform init code, and for optional regulators always seem to
return -EPROBE_DEFER for the legacy booting.
Let's fix the issue by checking for device tree based booting for
now. Then when omap3 boots in device tree only mode, this patch
can be just reverted.

This reverts commit c55d7a0553643a7e8f120688b82b594471084d3c.
Without reverting this commit we get "unbalanced disables for pbias_mmc_omap4"
errors on omap4430. It seems that 4430 and 4460 behave in a different way for
the PBIAS regulator registers and until that has been debugged further we
cannot rely on the regulator status registers in hardare on 4430.

Most distributions end up enabling SWIOTLB already with 32-bit
kernels due to the combination of CONFIG_HYPERVISOR_GUEST|CONFIG_XEN=y
as those end up requiring the SWIOTLB.
However for those that are not interested in virtualization and
run in 32-bit they will discover that: "32-bit PAE 4.2.0 kernel
(no IOMMU code) would hang when writing to my USB disk. The kernel
spews million(-ish messages per sec) to syslog, effectively
"hanging" userspace with my kernel.
Oct 2 14:33:06 voodoochild kernel: [ 223.287447] nommu_map_sg:
overflow 25dcac000+1024 of device mask ffffffff
Oct 2 14:33:06 voodoochild kernel: [ 223.287448] nommu_map_sg:

Oct 2 14:33:06 voodoochild kernel: [ 223.287449] nommu_map_sg:
overflow 25dcac000+1024 of device mask ffffffff
... etc ..."
Enabling it makes the problem go away.
N.B. With a6dfa128ce5c414ab46b1d690f7a1b8decb8526d
"config: Enable NEED_DMA_MAP_STATE by default when SWIOTLB is selected"
we also have the important part of the SG macros enabled to make this
work properly - in case anybody wants to backport this patch.

ASoC: Fixes for v4.3
Quite a few fixes here but they're all very small and driver specific,
none of them really stand out if you aren't using the relevant hardware
but they're all useful if you do happen to have an affected device.

3w controller don't dma map small single SGL entry commands but instead

perf_regs.c does not get built on Powerpc as CONFIG_PERF_REGS is false.
So the weak definition for 'sample_regs_masks' doesn't get picked up.
Adding perf_regs.o to util/Build unconditionally, exposes a redefinition
error for 'perf_reg_value()' function (due to the static inline version
in util/perf_regs.h). So use #ifdef HAVE_PERF_REGS_SUPPORT' around that
function.

Pull strscpy fixes from Chris Metcalf :
"This patch series fixes up a couple of architecture issues where
strscpy wasn't configured correctly (missing on h8300, duplicating
local and asm-generic copies on powerpc and tile).
It also adds a use of zero_bytemask() to the final store for strscpy
to avoid writing uninitialized data to the destination. However, to
make this work we had to add support for zero_bytemask() to the two
architectures that didn't have it (alpha and tile), because they were
providing their own local copies, but didn't provide the
zero_bytemask() that was previously only required when building with
CONFIG_DCACHE_WORD_ACCESS"
[ Side note: there is still no actual users of strscpy except for the
one preexisting use in arch/tile that predates the generic version.
So this is all about fixing the infrastructure so that we eventually
can start using it. - Linus ]
