Subject[patch 24/37] sparc: Fix ptrace() detach.
2.6.25-stable review patch.  If anyone has any objections, please let us
know.

------------------
From: David S. Miller <davem@davemloft.net>

[ Upstream commit: 986bef854fab44012df678a5b51817d5274d3ca1 ]

Forever we had a PTRACE_SUNOS_DETACH which was unconditionally
recognized, regardless of the personality of the process.

Unfortunately, this value is what ended up in the GLIBC sys/ptrace.h
header file on sparc as PTRACE_DETACH and PT_DETACH.

So continue to recognize this old value. Luckily, it doesn't conflict
with anything we actually care about.
