[parisc-linux-cvs] fix single stepping under 64 bit kernel

[Richard Hirst]

This patch makes ptrace single step and branch step work under a 64
bit kernel.  Peviously only tracing of syscalls worked.
Hmm, maybe I should have made struct pa_psw a set of bit fields in
an unsigned long instead, with the top 32 bits ifdef __LP64__ ...
