[PATCH 1/5] mn10300: Avoid SIGSEGV delivery loop

[David Howells]

From: Al Viro <viro@xxxxxxxxxxxxxxxx>

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.
