From ad0acab4557a91a60251b3ffe3478fad572d6f61 Mon Sep 17 00:00:00 2001 From: Al Viro Date: Mon, 20 Sep 2010 15:13:14 +0100 Subject: [PATCH] frv: avoid infinite loop of SIGSEGV delivery 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.
