Pull PCI / ACPI fix from Rafael Wysocki:
 "This fixes a bug uncovered by a recent driver core change that
  modified the implementation of the ACPI_COMPANION_SET() macro to
  strictly rely on its second argument to be either NULL or a valid
  pointer to struct acpi_device.

  As it turns out, pcibios_root_bridge_prepare() on x86 and ia64 works
  with the assumption that the only code path calling pci_create_root_bus()
  is pci_acpi_scan_root() and therefore the sysdata argument passed to
  it will always match the expectations of pcibios_root_bridge_prepare().

  That need not be the case, however, and in particular it is not the
  case for the Xen pcifront driver that passes a pointer to its own
  private data strcture as sysdata to pci_scan_bus_parented() which then
  passes it to pci_create_root_bus() and it ends up being used incorrectly
  by pcibios_root_bridge_prepare()"

Correct a regression introduced with 8453eebd [MIPS: Fix strnlen_user()
return value in case of overlong strings.] causing assembler warnings
and broken code generated in __strnlen_kernel_nocheck_asm:

arch/mips/lib/strnlen_user.S: Assembler messages:
arch/mips/lib/strnlen_user.S:64: Warning: Macro instruction expanded into multiple instructions in a branch delay slot

with the CPU_DADDI_WORKAROUNDS option set, resulting in the function
looping indefinitely upon mounting NFS root.

Use conditional assembly to avoid a microMIPS code size regression.
Using $at unconditionally would cause such a regression as there are no
16-bit instruction encodings available for ALU operations using this
register.  Using $v1 unconditionally would produce short microMIPS
encodings, but would prevent this register from being used across calls
to this function.

The extra LI operation introduced is free, replacing a NOP originally
scheduled into the delay slot of the branch that follows.

bmips_wr_vec() copies exception vector code from start to dst.

The call to dma_cache_wback() needs to flush (end-start) bytes,
starting at dst, from write-back cache to memory.

Since commit 100832abf065bc18 ("usb: isp1760: Make HCD support
optional"), CONFIG_USB_ISP1760_HCD is automatically selected when
needed.  Enabling that option in the defconfig is now a no-op, and no
longer enables ISP1760 HCD support.

Re-enable the ISP1760 driver in the defconfig by enabling
USB_ISP1760_HOST_ROLE instead.

Merge "The i.MX fixes for 4.1, 3rd round" from Shawn Guo:

It includes a couple of fixes for i.MX6 GPC code to let the new kernel
be able to boot with old DTBs:

 - Booting v4.1-rc kernel with old DTBs will fail with a fat warning
   (require low-level debug to be seen), due to the adoption of stacked
   IRQ domain.  The first fix improves the situation by allowing kernel
   boot up with old DTBs, although suspend/resume still breaks.

 - Booting new kernel with old DTBs that do not have power-domain info
   will result in a hang.  The second patch fixes the hang by skipping
   the kernel power-domain registration if DTB has no power-domain info.
