Pull libnvdimm fixes from Dan Williams:
- A collection of crash and deadlock fixes for DAX that are also tagged
for -stable. We will look to re-enable DAX pmd mappings in 4.5, but
for now 4.4 and -stable should disable it by default.
- A fixup to ext2 and ext4 to mirror the same warning emitted by XFS
when mounting with "-o dax"
* 'libnvdimm-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/nvdimm/nvdimm:
block: protect rw_page against device teardown
mm, dax: fix DAX deadlocks (COW fault)
dax: disable pmd mappings
ext2, ext4: warn when mounting with dax enabled
- Revert three recent intel_pstate driver commits one of which
introduced a regression and the remaining two depend on the
problematic one (Rafael Wysocki).
- Fix breakage related to the recently introduced ACPI _CCA object
support in the PCI DMA setup code (Suravee Suthikulpanit).
- Fix up the recently introduced ACPI CPPC support to only
use the hardware-reduced version of the PCCT structure as
the only architecture to support it (ARM64) will only use
hardware-reduced ACPI anyway (Ashwin Chaugule).
- Fix a cpufreq mediatek driver build problem (Arnd Bergmann).
- Fix the SMBus transaction handling implementation in the ACPI
core to avoid re-entrant calls to wait_event_timeout() which
makes intermittent boot stalls related to the Smart Battery
Subsystem initialization go away and revert a workaround of
another problem with the same underlying root cause (Chris
Bainbridge).
- Fix the generic wakeup interrupts framework to avoid using
invalid IRQ numbers (Dmitry Torokhov).
- Remove a redundant check from the ACPI EC driver (Markus Elfring).
- Modify the intel_pstate driver so it can support more Atom flavors
than just one (Baytrail) and add support for Atom Airmont cores
(which require new freqnency tables) to it (Philippe Longepe).
- Clean up MSR-related symbols in turbostat (Len Brown).

Pull more power management and ACPI updates from Rafael Wysocki:
"These are mostly fixes and cleanups (ACPI core, PM core, cpufreq, ACPI

It turned out that many HP laptops suffer from the same problem as
fixed in commit [c932b98c1e47: ALSA: hda - Apply pin fixup for HP
ProBook 6550b]. But, it's tiresome to list up all such PCI SSIDs, as
there are really lots of HP machines.
Instead, we do a bit more clever, try to check the supposedly dock and
built-in headphone pins, and apply the fixup when both seem valid.
This rule can be applied generically to all models using the same
quirk, so we'll fix all in a shot.

Now all important things are there:

There is also ttyUSB0, but it is not usable, at least not for at.
The device works well with qmi and ModemManager-NetworkManager.

This patch fixes a bug introduced by previous commit,
which incorrectly checkes the of_node of the end-point device.
Instead, it should check the of_node of the host bridge.

Instead of using a page pool, we can save memory by only allocating room
for 64 entries for the ppa command. Introduce a ppa_cache to allocate only
the required memory for the ppa list.

This patch fixes a memory leak that occurs when an endpoint fails to enqueue
the request. If that happens the complete function will never be called, thus
never freeing the request.

This makes sure f_midi doesn't try to enqueue data when the IN endpoint is

Fixes commit 09a75e8577
("usb: dwc2: refactor common low-level hw code to platform.c")
The above commit consolidated the low-level phy access into a common
location. This change made the otg clk a requirement and broke some
platforms when it was moved into platform.c.
So make clk handling optional again.

When searching for PHYs, any error was treated as if the PHY did not
exist or was not specified. Thus the probe function did not
correctly return error conditions such as -EPROBE_DEFER.
Fixed so that only a non-existing PHY is ignored and any other error
is returned.
