Subject: [PATCH] [IA64] die_if_kernel() can return (CVE-2006-0742)

arch/ia64/kernel/unaligned.c erroneously marked die_if_kernel()
with a "noreturn" attribute ... which is silly (it returns whenever
the argument regs say that the fault happened in user mode, as one
might expect given the "if_kernel" part of its name!).  Thanks to
Alan and Gareth for pointing this out.
