[parisc-linux] preliminary strace patch

[Helge Deller]

I noticed, that strace was pretty much useless/broken, if you use shared memory/ipc calls or the stat64() syscall.

Example:
root at c3000:~# strace df -h / 
[....]
write(1, "Filesystem            Size  Used"..., 55Filesystem            Size  Used Avail Use% Mounted on
) = 55
upeek: ptrace(PTRACE_PEEKUSER,29538,4294967292,0): Input/output error

Below is a patch against strace-4.5.15 source package from sourceforge.
Maybe it's useful to some people here, although it's not cleaned up/correct at all yet.
Feedback/corrections (esp. for the new syscalls >= 295) are welcome, because I only focused on statfs64()/fstatfs64() at this moment.
