Merge branch 'parisc-for-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Pull parisc updates from Helge Deller:
 "Main fixes and updates in this patch series are:
   - we faced kernel stack corruptions because of multiple delivery of
     interrupts
   - added kernel stack overflow checks
   - added possibility to use dedicated stacks for irq processing
   - initial support for page sizes > 4k
   - more information in /proc/interrupts (e.g.  TLB flushes and number
     of IPI calls)
   - documented how the parisc gateway page works
   - and of course quite some other smaller cleanups and fixes."
