Pull "ARMv7 VExpress fixes for v4.10" from Sudeep Holla:

A simple fix to extend GICv2 CPU interface registers from 4K to 8K
on VExpress TC1 and TC2 platforms in order to support split priority
drop and interrupt deactivation.

Pull "i.MX fixes for 4.10" from Shawn Guo:

 - A format fix for vf610-zii-dev-rev-b.dts, which has a very odd line
   due to misses a newline.
 - A fix to imx-weim bus error seen on board which doesn't actually use
   the bus.
 - A fix for imx6qdl-nitrogen6x board which has conflicting usage of
   pad NANDF_CS2.
 - A cleanup on i.MX1 machine to remove .map_io callback, which also
   fixes a compiling error for NOMMU build.
 - Fix AVIC base address in i.MX31 device tree source.  The problem was
   shadowed by the AVIC driver, which takes the correct base address
   from a SoC specific header file.

Pull "omap fixes for v4.10-rc cycle" from Tony Lindgren:

Fist set of fixes for omaps for v4.10-rc cycle, mostly
to deal with various regressions noticed during the merge
window and to fix various device tree configurations for
boards. Also included is removal of mach-omap2/gpio.c that
is now dead code with device tree based booting that should
be OK for the early -rc cycle:

- A series of fixes to add empty chosen node to fix regressions
  caused for bootloaders that don't create chosen node as the
  decompressor needs the chosen node to merge command line and
  ATAGs into it

- Fix missing logicpd-som-lv-37xx-devkit.dtb entry in Makefile

- Fix regression for am437x timers

- Fix wrong strcat for non-NULL terminated string

- A series of changes to fix tps65217 interrupts to not use
  defines as we don't do that for interrupts

- Two patches to fix USB VBUS detection on am57xx-idk and force it
  to peripheral mode until dwc3 role detection is working

- Add missing dra72-evm-tps65917 missing voltage supplies
  accidentally left out of an earlier patch

- Fix n900 eMMC detection when booted on qemu

- Remove unwanted pr_err on failed memory allocation for
  prm_common.c

- Remove legacy mach-omap2/gpio.c that now is dead code
  since we boot mach-omap2 in device tree only mode

- Fix am572x-idk pcie1 by adding the missing gpio reset pin

76138f94a3 ARM: dts: armada388-clearfog: split clearfog DTS file
There are two versions of the clearfog - a base and a pro model.  The
base model has an additional PHY on eth1, replacing the DSA switch on
the pro model.  MPP assignments are slightly different.  The base model
also omits the second PCIe, and footprint for a PIC microcontroller.

In order to cater for these differences, move all the existing clearfog
support to a dtsi file before starting to modify it, to make the
following changes more clear.

819da1ead1 MIPS: c-r4k: Treat I6400 dcache as though physically indexed
The L1 data cache in I6400 CPUs is indexed by physical address bits if
an entry for the address is present in the DTLB early enough in the
pipelined execution of a memory access instruction. If an entry is not
present then it's indexed by virtual address bits, but hardware will
check in a later pipeline stage when a DTLB entry has been created
whether the virtual address bits used match the physical address bits,
and if not will transparently restart the memory access instruction.

This means that although it isn't always physically indexed, it appears
so to software & we can treat the I6400 L1 data cache as being
physically indexed in order to avoid considering aliasing.

a8b3b0c94a MIPS: Netlogic: Fix assembler warning from smpboot.S
The netlogic platform can be built for either MIPS32 or MIPS64, and when
built for MIPS32 (as by nlm_xlr_defconfig) the use of the dla
pseudo-instruction leads to warnings such as the following from recent
versions of the GNU assembler:

  arch/mips/netlogic/common/smpboot.S: Assembler messages:
  arch/mips/netlogic/common/smpboot.S:62: Warning: dla used to load 32-bit register; recommend using la instead
  arch/mips/netlogic/common/smpboot.S:63: Warning: dla used to load 32-bit register; recommend using la instead

Avoid these warnings by using the PTR_LA macro to make use of the
appropriate la or dla pseudo-instruction for the build.

08889582b8 MIPS: End asm function prologue macros with .insn
When building a kernel targeting a microMIPS ISA, recent GNU linkers
will fail the link if they cannot determine that the target of a branch
or jump is microMIPS code, with errors such as the following:

    mips-img-linux-gnu-ld: arch/mips/built-in.o: .text+0x542c:
    Unsupported jump between ISA modes; consider recompiling with
    interlinking enabled.
    mips-img-linux-gnu-ld: final link failed: Bad value

or:

    ./arch/mips/include/asm/uaccess.h:1017: warning: JALX to a
    non-word-aligned address

Placing anything other than an instruction at the start of a function
written in assembly appears to trigger such errors. In order to prepare
for allowing us to follow function prologue macros with an EXPORT_SYMBOL
invocation, end the prologue macros (LEAD, NESTED & FEXPORT) with a
.insn directive. This ensures that the start of the function is marked
as code, which always makes sense for functions & safely prevents us
from hitting the link errors described above.

2c0e57eaef MIPS: tlbex: Clear ISA bit when writing to handle_tlb{l,m,s}
When generating TLB exception handling code we write to memory reserved
at the handle_tlbl, handle_tlbm & handle_tlbs symbols. Up until now the
ISA bit has always been clear simply because the assembly code reserving
the space for those functions places no instructions in them. In
preparation for marking all LEAF functions as containing code,
explicitly clear the ISA bit when calculating the addresses at which to
write TLB exception handling code.

cd854fc6f1 MIPS: uprobes: Remove __weak attribute from arch_uprobe_copy_ixol.
Arch-specific implementation of arch_uprobe_copy_ixol is expected to
override the weak implementation in generic code.
As currently both implementations are marked as weak, it is up to the
linker to chose one. Remove the __weak attribute from MIPS code to make
sure the correct version is used.
