[GIT PULL] parisc architecture updates for kernel v5.9

[Helge Deller]

Hi Linus,

please pull another set of patches for the parisc architecture for kernel 5.9-rc1 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.9-2

This patchset includes:
- 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

Thanks,
Helge
