External IRQ0 has the same capabilities as the other IRQ1-7 and is
handled by the same register IPIC_SEPNR. When this register is not
specified for "ack" in "ipic_info", you cannot configure this IRQ as

There is no reason for that message to be pr_info(), it will be printed
every time we start a KVM guest.

On POWER9 the ERAT may be incorrect on wakeup from some stop states
that lose state. This causes random segvs and illegal instructions
when these stop states are enabled.
This patch invalidates the ERAT on wakeup on POWER9 to prevent this
from causing a problem.

Now that ioread64 and iowrite64 are always available we don't

During secondary start, we do not need to BUG_ON if an invalid CPU number
is passed. We alreay print an error if secondary cannot be started, so
just return an error instead.
