[PATCH 1/2] powerpc/msi: Fix the msi bitmap alignment tests

When we added the alignment tests recently we failed to check they were actually passing - oops. They weren't passing, because the bitmap was full. We should also be a bit more careful when checking the return code, a negative error return could by divisible by our alignment value. Fixes:

[PATCH 2/2] powerpc/msi: Use WARN_ON() in msi bitmap selftests

As demonstrated in the previous commit, the failure message from the msi bitmap selftests is a bit subtle, it's easy to miss a failure in a busy boot log. So drop our check() macro and use WARN_ON() instead. This necessitates inverting all the conditions as well. Signed-off-by: Michael Ellerman

Re: [PATCH tty-next 14/22] tty: Remove tty_wait_until_sent_from_close()

The point being that holding the tty lock across the _entire_ close is equivalent to the current outcome, regardless of O_NONBLOCK. I'm reluctant to start returning EGAIN for non-blocking tty opens because no tty driver does that now, and I don't think userspace will deal well with new
