Merge branch 'parisc-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
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
* 'parisc-5.9-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Implement __smp_store_release and __smp_load_acquire barriers
parisc: mask out enable and reserved bits from sba imask
parisc: Whitespace cleanups in atomic.h
parisc/kernel/ftrace: Remove function callback casts
sections.h: dereference_function_descriptor() returns void pointer
