[POWERPC] Fix ppc32 single-stepping out of syscalls
The ppc32 kernel didn't properly set/clear the TIF_SINGLESTEP flag, causing return from syscalls to not SIGTRAP, thus executing one more instruction before stopping again. This fixes it. The ptrace code is a bit of a mess, and is overdue for at least a -proper- 32/64 bits split and possibly more cleanups but this minimum fix should be ok for 2.6.22 Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
