arm: if we get into work_pending while returning to kernel mode, just go away checking in do_signal() is pointless - if we get there with !user_mode(regs) (and we might), we'll end up looping indefinitely. Check in work_pending and break out of the loop if so. Acked-by: Russell King <rmk+kernel@arm.linux.org.uk> Signed-off-by: Al Viro <viro@zeniv.linux.org.uk>
