#     Merge branch 'parisc-4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
#     
#     Pull parisc updates from Helge Deller:
#      "Lots of small fixes and enhancements, most noteably:
#     
#        - Many TLB and cache flush optimizations (Dave)
#     
#        - Fixed HPMC/crash handler on 64-bit kernel (Dave and myself)
#     
#        - Added alternative infrastructre. The kernel now live-patches itself
#          for various situations, e.g. replace SMP code when running on one
#          CPU only or drop cache flushes when system has no cache installed.
#     
#        - vmlinuz now contains a full copy of the compressed vmlinux file.
#          This simplifies debugging the currently booted kernel.
#     
#        - Unused driver removal (Christoph)
#     
#        - Reduced warnings of Dino PCI bridge when running in qemu
#     
#        - Removed gcc version check (Masahiro)"
