Pull parisc architecture fixes from Helge Deller:
- Fix PTRACE_GETREGS/PTRACE_SETREGS for 32-bit userspace on a 64-bit
kernel
- pdc_iodc_print() dropped chars for newline in strings
- Drop constants in favour of PRIV_USER
- use safer strscpy() function in pdc_stable driver
* tag 'parisc-for-6.2-rc7' of git://git.kernel.org/pub/scm/linux/kernel/git/deller/parisc-linux:
parisc: Wire up PTRACE_GETREGS/PTRACE_SETREGS for compat case
parisc: Replace hardcoded value with PRIV_USER constant in ptrace.c
parisc: Fix return code of pdc_iodc_print()
parisc: pdc_stable: use strscpy() to instead of strncpy()
