[GIT PULL] parisc architecture updates for v4.13

[Helge Deller]

Hi Linus,

please pull fixes and enhancements for the parisc architecture for kernel 4.13-rc1 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.13-1

Main changes are:

- Added support to the parisc dma functions to return DMA_ERROR_CODE if DMA
  isn't possible. This fixes a long standing kernel crash if parport_pc is
  enabled (by Thomas Bogendoerfer, marked for stable series).

- Use the compat_sys_keyctl() in compat mode (by Eric Biggers, marked for stable
  series).
 
- Initial support for the Page Deallocation Table (PDT) which is maintained by
  firmware and holds the list of memory addresses which had physical errors.
  By checking that list we can prevent Linux to use those broken memory areas.

- Ensure IRQs are off in switch_mm().

- Report SIGSEGV instead of SIGBUS when running out of stack.

- Mark the cr16 clocksource stable on single-socket and single-core machines.

Thanks,
Helge
