Modified files:
	include/asm-parisc: thread_info.h 

Log message:
SECURITY ALERT:

Calling sys_restart_syscall without having taking a signal
across a syscall leaves the restart_block uninitialized,
allowing malicious user code to crash the kernel.

FIX:

Define INIT_THREAD_INFO such that restart_block.fn is set to
the default do_not_restart_syscall.

PLEASE UPDATE YOUR KERNEL!
