s390/lowcore: replace lowcore irb array with a per-cpu variable
Remove the 96-byte irb array from the lowcore and create a per-cpu variable instead. That way we will pick up any change in the definition of the struct irb automatically. Acked-By: Sebastian Ott <sebott@linux.vnet.ibm.com> Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
