Pull parisc updates from Helge Deller:
"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"
