OK, nobody cares ;)

So I am going to ask Ingo to pull these changes plus the following minor fix.

To remind, I think that traps.c needs more cleanups: do_general_protection()
and math_error() should be converted into DO_ERROR(), DIE_GPF should die, and
the users of show_unhandled_signals() should be unified/cleanuped.

Ananth, David, this is x86 specific, but at first glance powerpc/arm might
want to use uprobe_get_trap_addr() too.

Oleg.
