From: Matt Fleming <matt.fleming@intel.com>
Instead of open coding the sequence from force_sigsegv() just call it. This also fixes a bug because we were modifying ka->sa.sa_handler (which is a copy of sighand->action[]), whereas the intention of the code was to modify sighand->action[] directly.
As the original code was working with a copy it had no effect on signal delivery.
