Merge branch 'parisc-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux

Browse Source 
Pull more parisc updates from Helge Deller:

 - Oscar Carter contributed a patch which fixes parisc's usage of
   dereference_function_descriptor() and thus will allow using the
   -Wcast-function-type compiler option in the top-level Makefile

 - Sven Schnelle fixed a bug in the SBA code to prevent crashes during
   kexec

 - John David Anglin provided implementations for __smp_store_release()
   and __smp_load_acquire barriers() which avoids using the sync
   assembler instruction and thus speeds up barrier paths

 - Some whitespace cleanups in parisc's atomic.h header file
