Bodo Stroesser ab1c23c244 [PATCH] SYSEMU: fix sysaudit / singlestep interaction
Paolo 'Blaisorblade' Giarrusso <blaisorblade@yahoo.it>

This is simply an adjustment for "Ptrace - i386: fix Syscall Audit interaction
with singlestep" to work on top of SYSEMU patches, too.  On this patch, I have
some doubts: I wonder why we need to alter that way ptrace_disable().

I left the patch this way because it has been extensively tested, but I don't
understand the reason.

The current PTRACE_DETACH handling simply clears child->ptrace; actually this
is not enough because entry.S just looks at the thread_flags; actually,
do_syscall_trace checks current->ptrace but I don't think depending on that is
good, at least for performance, so I think the clearing is done elsewhere.
For instance, on PTRACE_CONT it's done, but doing PTRACE_DETACH without
PTRACE_CONT is possible (and happens when gdb crashes and one kills it
manually).
