From: Rusty Russell <rusty@rustcorp.com.au>

There's a really nice console helper (esp.  for virtual console drivers) in
drivers/char/hvc_console.c.  It has only ever been used for PowerPC, though,
so it uses NO_IRQ which is only defined there.

Let's fix that so it's more widely useful.  By, say, lguest.
