#     Merge tag 'powerpc-4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/powerpc/linux
#     
#     Pull powerpc fixes from Michael Ellerman:
#     
#      - An implementation for the newly added hv_ops->flush() for the OPAL
#        hvc console driver backends, I forgot to apply this after merging the
#        hvc driver changes before the merge window.
#     
#      - Enable all PCI bridges at boot on powernv, to avoid races when
#        multiple children of a bridge try to enable it simultaneously. This
#        is a workaround until the PCI core can be enhanced to fix the races.
#     
#      - A fix to query PowerVM for the correct system topology at boot before
#        initialising sched domains, seen in some configurations to cause
#        broken scheduling etc.
#     
#      - A fix for pte_access_permitted() on "nohash" platforms.
#     
#      - Two commits to fix SIGBUS when using remap_pfn_range() seen on Power9
#        due to a workaround when using the nest MMU (GPUs, accelerators).
#     
#      - Another fix to the VFIO code used by KVM, the previous fix had some
#        bugs which caused guests to not start in some configurations.
#     
#      - A handful of other minor fixes.
#

#     Mackerras, Srikar Dronamraju.
