Merge branch 'parisc-4.19-2' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux
Pull more parisc updates from Helge Deller:
- fix boot failure of 64-bit kernel. It got broken by the unwind
optimization commit in merge window.
- fix 64-bit userspace support (static 64-bit applications only, e.g.
we don't yet have 64-bit userspace support in glibc).
- consolidate unwind initialization code.
- add machine model description to stack trace.
