[GIT PULL] parisc architecture updates for 4.15

[Helge Deller]

Hi Linus,

please pull parisc architecture updates for the merge window of kernel 4.15 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.15-1


Highlights:

- One important fix from Dave to prevent kernel crash when userspace hands over
  invalid values to our in-kernel CAS implementation.

- Added CPU topology support, including multi-core scheduler support on PA8900
  CPUs

Minor changes:

- Minor fixes for sparse (from Luc)

- Drop duplicates for CPU_BIG_ENDIAN from parisc and sparc top Kconfig files
  (from Babu)

- Reorganized parisc PDC (firmware-access) header files for usage from
  userspace. Required for upcoming qemu parisc emulator and SeaBIOS fork
  to support parisc.

Thanks,
Helge
