a4fdb2a46f arm64 updates for 4.3:
- Support for new architectural features introduced in ARMv8.1:
   * Privileged Access Never (PAN) to catch user pointer dereferences in
     the kernel
   * Large System Extension (LSE) for building scalable atomics and locks
     (depends on locking/arch-atomic from tip, which is included here)
   * Hardware Dirty Bit Management (DBM) for updating clean PTEs
     automatically
 
 - Move our PSCI implementation out into drivers/firmware/, where it can
   be shared with arch/arm/. RMK has also pulled this component branch
   and has additional patches moving arch/arm/ over. MAINTAINERS is
   updated accordingly.
 
 - Better BUG implementation based on the BRK instruction for trapping
 
 - Leaf TLB invalidation for unmapping user pages
 
 - Support for PROBE_ONLY PCI configurations
 
 - Various cleanups and non-critical fixes, including:
   * Always flush FP/SIMD state over exec()
   * Restrict memblock additions based on range of linear mapping
   * Ensure *(LIST_POISON) generates a fatal fault
   * Context-tracking syscall return no longer corrupts return value when
     not forced on.
   * Alternatives patching synchronisation/stability improvements
   * Signed sub-word cmpxchg compare fix (tickled by HAVE_CMPXCHG_LOCAL)
   * Force SMP=y
   * Hide direct DCC access from userspace
   * Fix EFI stub memory allocation when DRAM starts at 0x0

8d01b66b4f ARM: SoC 64-bit changes for v4.3
Here's our branch of ARM64 contents for this merge window.
 
 Most of this is DT contents for new SoCs (or those who have seen new
 device support added). Maybe we should stop separating out the arm64
 contents here to avoid the kind of internal conflicts as we got this
 time around, where 32- and 64-bit contents conflicted.
 
 Anyhow, on the actual contents:
 
 New SoCs:
 
 - Broadcom North Star 2 (ns2)
 - Marvell Berlin4CT
 - Mediatek MT6795
 - Rockchip RK3368
 
 In addition, there are enhancements for the following platforms:
 
 - Mediatek MT8173: cpuidle-dt updates, misc other additions
 - ZyncMP: A bunch of devices added to the existing DTSI
 - Qualcomm MSM8916 and APQ8016 updates for USB, etc.
 
 + A handful of other updates for various platforms

341a670abd ARM64: dts: vexpress: Use assigned-clock-parents for sp810
The sp810 clk driver is calling the clk consumer APIs from
clk_prepare ops to change the parent to a 1 MHz fixed rate clock
for each of the clocks that the driver provides. Use
assigned-clock-parents for this instead of doing it in the driver
to avoid using the consumer API in provider code. This also
allows us to remove the usage of clk provider APIs that take a
struct clk as an argument from the sp810 driver.

Each X-Gene PCIe node will now have two memory windows: a 32-bit
non-prefetchable window and a 64-bit prefetchable window.

b790c2cab5 arm64: dts: add Rockchip rk3368 core dtsi and board dts for the r88 board
In terms of peripherals the rk3368 is quite similar to the rk3288, which
makes it possible to have a lot basic components working in the first go.
More to follow once I tracked down all the tiny differences that still
exist in some parts.

With these dts files, the R88 board is able to boot from an attached
usb device and most likely from its emmc too, if the emmc uses a standard
partition table instead of Rockchip's own one - the emmc itself is
detected correctly.

Add MT8173 I2C device nodes, include I2C controllers and pins.
MT8173 has six I2C controllers, from i2c0 to i2c6, exclude i2c5.
The 6th I2C controller register base doesn't next to 5th I2C,
and there is a hardware between 5th and 6th I2C controller. So
SoC designer name 6th controller as "i2c6", not "i2c5".
