Pull USB/PHY updates from Greg KH:
"Here is the big USB and PHY driver updates for 4.11-rc1.
Nothing major, just the normal amount of churn in the usb gadget and

drivers.
All have been in linux-next for a long time with no reported issues"

git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
Pull powerpc updates from Michael Ellerman:
"Highlights include:
- Support for direct mapped LPC on POWER9, giving Linux direct access
to devices that may be on there such as a UART.
- Memory hotplug support for the Power9 Radix MMU.
- Add new AUX vectors describing the processor's cache geometry, to
be used by glibc.
- The ability for a guest to ask the hypervisor to resize the guest's
hash table, and in addition support for doing so automatically when
memory is hotplugged into/out-of the guest. This allows the hash
table to be sized based on the current memory usage of the guest,
rather than the maximum possible memory usage.
- Implementation of optprobes (kprobe optimisation) for powerpc.
In addition there's the topic branch shared with the KVM tree, which
includes support for guests to use the Radix MMU on Power9.

By default CONFIG_INTEL_IOMMU_DEFAULT_ON is not set and thus
dmar_disabled variable is set.
Intel IOMMU driver based on above doesn't set intel_iommu_enabled
variable.
The commit b0119e870837 ("iommu: Introduce new 'struct iommu_device'")
mistakenly assumes it never happens and tries to unregister not ever
registered resources, which crashes the kernel at boot time:
BUG: unable to handle kernel NULL pointer dereference at 0000000000000008
IP: iommu_device_unregister+0x31/0x60

In the transition from using rproc_da_to_va(), the type of the load
offset became unsigned. This causes the subsequent check to let negative
values less than p_memsz + mem_size through and we write outside of the
buffer.
Change the type back to a signed value to catch this.

git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl
Pull pin control updates from Linus Walleij:
"Pin control bulk changes for the v4.11 kernel cycle.
Core changes:
- Switch the generic pin config argument from 16 to 24 bits, only use
8 bits for the configuration type. We might need to encode more
information about a certain setting than we need to encode
different generic settings.
- Add a cross-talk API to the pin control GPIO back-end, utilizing
pinctrl_gpio_set_config() from GPIO drivers that want to set up a
certain pin configuration in the back-end.
This also includes the .set_config() refactoring of the GPIO chips,
so that they pass a generic configuration for things like
debouncing and single ended (typically open drain). This change has
also been merged in an immutable branch to the GPIO tree.
- Take hogs with a delayed work, so that we finalize probing a pin
controller before trying to get any hogs.
- For pin controllers putting all group and function definitions into
the device tree, we now have generic code to deal with this and it
is used in two drivers so far.
- Simplifications of the pin request conflict check.
- Make dt_free_map() optional.
Updates to drivers:
- pinctrl-single now use the generic helpers to generate dynamic
group and function tables from the device tree.
- Texas Instruments IOdelay configuration driver add-on to
pinctrl-single.
- i.MX: use radix trees to store groups and functions, use the new
generic group and function helpers to manage them.
- Intel: add support for hardware debouncing and 1K pull-down. New
subdriver for the Gemini Lake SoC.
- Renesas SH-PFC: drive strength and bias support, CAN bus muxing,
MSIOF, SDHI, HSCIF for r8a7796. Gyro-ADC supporton r8a7791.
- Aspeed: use syscon cross-dependencies to set up related bits in the
LPC host controller and display controller.
- Aspeed: finalize G4 and G5 support. Fix mux configuration on GPIOs.
Add banks Y, Z, AA, AB and AC.
- AMD: support additional GPIO.
- STM32: set this controller to strict muxing mode. STM32H743 MCU
support.
- Allwinner sunxi: deep simplifications on how to support subvariants
of SoCs without adding to much SoC-specific data for each
subvariant, especially for sun5i variants. New driver for V3s SoCs.
New driver for the H5 SoC. Support A31/A31s variants with the new
variant framework.
- Mvebu: simplifications to use a MMIO and regmap abstraction. New
subdrivers for the 98DX3236, 98DX5241 SoCs.
- Samsung Exynos: delete Exynos4415 support. Add crosstalk to the SoC
driver to access regmaps. Add infrastructure for pin-bank retention
control. Clean out the pin retention control from
arch/arm/mach-exynos and arch/arm/mach-s5p and put it properly in
the Samsung pin control driver(s).
- Meson: add HDMI HPD/DDC pins. Add pwm_ao_b pin.
- Qualcomm: use raw spinlock variants: this makes the qualcomm driver
realtime-safe"

Commit 279967a65b32 ("HID: rmi: Handle all Synaptics touchpads using hid-rmi")
unconditionally switches over handling of all Synaptics touchpads to hid-rmi
(to make use of extended features of the HW); in case CONFIG_HID_RMI is
disabled though this renders the touchpad unusable, as the
HID_DEVICE(HID_BUS_ANY, HID_GROUP_RMI, HID_ANY_ID, HID_ANY_ID)
match doesn't exist and generic/multitouch doesn't bind to it either (due
to hid group mismatch).
Fix this by switching over to hid-rmi only if it has been actually built.

The Armada 7K/8K use the same RTC IP than the Armada 38x. However the SOC
integration differs in 2 points:
- MBUS bridge timing initialization
- IRQ configuration at SoC level
Moreover the Armada 7K/8K have an issue preventing to get the interrupt
from alarm 1. This commit allows to use alarm 2 for these A7K/8K but to
still use alarm 1 for the Armada 38x.

When the fast blit path fails while attempting to move a buffer from RAM
to VRAM, we fall back to a CPU-based memcpy that cannot handle split VRAM
buffers. Instead of crashing, simply fail the buffer move.
Ideally, we would teach TTM about split buffers so that the fallback still
works in this case, but that is quite involved. So for now, apply the
simplest possible fix.

The vm fault handler relies on the fact that the VMA owns a reference
to the BO. However, once mmap_sem is released, other tasks are free to
destroy the VMA, which can lead to the BO being freed. Fix two code
paths where that can happen, both related to vm fault retries.
Found via a lock debugging warning which flagged &bo->wu_mutex as
locked while being destroyed.

The end_device and sas_host devices support BSG ioctls, but the
request_queue allocated for them isn't set up to allocate the struct
scsi_request payload. This leads to memory corruption in the call to
scsi_req_init() in bsg_map_hdr(), since it will memset past the end of
the allocated request. Fix it by setting ->cmd_size on the allocated
request_queue.
