Merge branch 'parisc-4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc updates from Helge Deller:

 - add Kernel address space layout randomization support

 - re-enable interrupts earlier now that we have a working IRQ stack

 - optimize the timer interrupt function to better cope with missed
   timer irqs

 - fix error return code in parisc perf code (by Dan Carpenter)

 - fix PAT debug code

* 'parisc-4.10-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
  parisc: Optimize timer interrupt function
  parisc: perf: return -EFAULT on error
  parisc: Enhance CPU detection code on PAT machines
  parisc: Re-enable interrupts early
  parisc: Enable KASLR
