parisc: Add ARCH_TRACEHOOK and regset support
By adding TRACEHOOK support we now get a clean user interface to access registers via PTRACE_GETREGS, PTRACE_SETREGS, PTRACE_GETFPREGS and PTRACE_SETFPREGS. The user-visible regset struct user_regs_struct and user_fp_struct are modelled similiar to x86 and can be accessed via PTRACE_GETREGSET. Signed-off-by: Helge Deller <deller@gmx.de>
