Merge branch 'parisc-5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux 

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"

* 'parisc-5.1-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux: (21 commits)
  parisc: use memblock_alloc() instead of custom get_memblock()
  parisc: Add constants for various PDC firmware calls
  parisc: Add constant for PDC_PAT_COMPLEX firmware call
  parisc: Show machine product number during boot
  parisc: Add constants for PDC_RELOCATE PDC call
  parisc: Add PDC_CRASH_PREP PDC function number
  parisc: Use F_EXTEND() macro in iosapic code
  parisc: remove the HBA_DATA macro
  parisc/lba_pci: use container_of in LBA_DEV
  parisc/dino: use container_of in DINO_DEV
  parisc: properly type the return value of parisc_walk_tree
  parisc: properly type the iommu field in struct pci_hba_data
  parisc: turn GET_IOC into an inline function
  parisc: move internal implementation details out of <asm/dma-mapping.h>
  parisc: don't include <asm/cacheflush.h> in <asm/dma-mapping.h>
  parisc: remove meaningless ccflags-y in arch/parisc/boot/Makefile
  parisc: replace oops_in_progress manipulation with bust_spinlocks()
  parisc: Improve initial IRQ to CPU assignment
  parisc: Count IPI function call interrupts
  parisc: Show rescheduling interrupts on SMP machines only
