serial: Patches for OCTEON CPU support.

Previously I have posted these five patches as part of the larger CPU support patch set. I am separating them out now as I have incorporated changes as suggested by Alan Cox, and these are ready for review now.

Changes from previous version:

* I/O functions now called serial_{in,out}.

* UART_BUG_OCTEON_IIR workaround moved to OCTEON serial_in function and out of this patch set.

Since these are the only non-mips specific patches required for OCTEON cpu support, it is necessary to get these Signed-off-by before the full OCTEON patch set can proceed. Also since serial is lacking active maintainers, I am sending directly to akpm and Alan in hopes that one or more of them will review the patches.

Five patches to follow.

David Daney (5):
8250: Don't clobber spinlocks.
8250: Serial driver changes to support future Cavium OCTEON serial
patches.
Serial: Allow port type to be specified when calling

    serial8250_register_port.

8250: Allow port type to specify bugs that are not probed for.
Serial: UART driver changes for Cavium OCTEON.
