Subject: [GIT PULL] parisc architecture updates for kernel v4.19

Hi Linus,

please pull fixes and updates for the parisc architecture for kernel 4.19 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.19-1

Changes include:
- parisc now uses the generic dma_noncoherent_ops implementation, by Christoph Hellwig.
- further memory barrier and spinlock improvements, by John David Anglin.
- prepare removal of current_text_addr() functions, by Nick Desaulniers.
- improve kernel stack unwinding on parisc, by me.
- drop ENOTSUP which was defined on parisc only, by me.

Thanks,
Helge

----------------------------------------------------------------
Christoph Hellwig (3):
      parisc: merge pcx_dma_ops and pcxl_dma_ops
      parisc: always use flush_kernel_dcache_range for DMA cache maintainance
      parisc: use generic dma_noncoherent_ops

Helge Deller (3):
      parisc: Drop architecture-specific ENOTSUP define
      parisc: Add HAVE_REGS_AND_STACK_ACCESS_API feature
      parisc: Fix and improve kernel stack unwinding

John David Anglin (2):
      parisc: Remove ordered stores from syscall.S
      parisc: Remove unnecessary barriers from spinlock.h

Nick Desaulniers (1):
      parisc: prefer _THIS_IP_ and _RET_IP_ statement expressions
