[GIT PULL] parisc fixes and updates for kernel v4.19

[Helge Deller]

Hi Linus,

please pull the second round of fixes and updates in this merge window
for the parisc architecture for kernel 4.19 from:

  git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-4.19-2

Changes:
- 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.

Thanks,
Helge
