[PATCH] x86_64: fix 2.6.18 regression - PTRACE_OLDSETOPTIONS should be accepted
Also PTRACE_OLDSETOPTIONS should be accepted, as done by kernel/ptrace.c
and forced by binary compatibility. UML/32bit breaks because of this -
since it is wise enough to use PTRACE_OLDSETOPTIONS to be binary compatible
with 2.4 host kernels.
Until 2.6.17 (commit f0f2d6536e3515b5b1b7ae97dc8f176860c8c2ce) we had:
default:
return sys_ptrace(request, pid, addr, data);
Instead here we have:
case PTRACE_GET_THREAD_AREA:
case ...:
return sys_ptrace(request, pid, addr, data);
default:
return -EINVAL;
This change was a style change - when a case is added, it must be
explicitly tested this way. In this case, not enough testing was done.
