parisc architecture updates for kernel v5.1

Hi Linus,

please pull four small parisc architecture fixes for kernel 5.1 from:

git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux.git parisc-5.1-2

A 32-bit boot regression fix introduced in the merge window, a QEMU detection fix and two fixes by Sven regarding ptrace & kprobes.

Thanks,
Helge
