Subject[PATCH 3/5] frv: avoid infinite loop of SIGSEGV delivery
Date
From: Al Viro <viro@ftp.linux.org.uk>

Use force_sigsegv() rather than force_sig(SIGSEGV, ...) as the former resets
the SEGV handler pointer which will kill the process, rather than leaving it
open to an infinite loop if the SEGV handler itself caused a SEGV signal.
