#     Pull parisc architecture fixes from Helge Deller:
#      "We had two big outstanding issues after v5.18-rc6:
#     
#        a) 32-bit kernels on 64-bit machines (e.g. on a C3700 which is able
#           to run 32- and 64-bit kernels) failed early in userspace.
#     
#        b) 64-bit kernels on PA8800/PA8900 CPUs (e.g. in a C8000) showed
#           random userspace segfaults. We assumed that those problems were
#           caused by the tmpalias flushes.
#     
#       Dave did a lot of testing and reorganization of the current flush code
#       and fixed the 32-bit cache flushing. For PA8800/PA8900 CPUs he
#       switched the code to flush using the virtual address of user and
#       kernel pages instead of using tmpalias flushes. The tmpalias flushes
#       don't seem to work reliable on such CPUs.
#     
#       We tested the patches on a wide range machines (715/64, B160L, C3000,
#       C3700, C8000, rp3440) and they have been in for-next without any
#       conflicts.
#     
#       Summary:
#     
#        - Rewrite the cache flush code for PA8800/PA8900 CPUs to flush using
#          the virtual address of user and kernel pages instead of using
#          tmpalias flushes. Testing showed, that tmpalias flushes don't work
#          reliably on PA8800/PA8900 CPUs
#     
#        - Fix flush code to allow 32-bit kernels to run on 64-bit capable
#          machines, e.g. a 32-bit kernel on C3700 machines"
