Pull parisc updates from Helge Deller:
"The most important changes in this patch set are:
- DMA-related cleanups for parisc with the aim to move anything not
required by drivers out of <asm/dma-mapping.h>, by Christoph
Hellwig
- Switch to memblock_alloc(), by Mike Rapoport
- Makefile cleanups by Masahiro Yamada
- Switch to bust_spinlocks(), by Sergey Senozhatsky
- Improved initial SMP affinity selection for IRQs
- Added IPI- and rescheduling interrupts in /proc/interrupts output"
