The sci_probe_single() path attempts to use sci_remove() for the error
path, while sci_remove() is still flagged as __devexit. So, we simply
discard the section annotation.

Presently this is special-cased for early initialization. While there are
situations where these static early initializations are still necessary,
with minor changes it is possible to use this for the regular ioremap
implementation as well. This allows us to kill off the special-casing for
the remap completely and to start tidying up all of the SH-5
special-casing in drivers.

With 2.6.30-rc1 on SMDK6410 I experience a soft lockup on bootup when
the Samsung serial driver attempts to disable the transmit interrupt
from within the transmit interrupt handler: it calls disable_irq()
which locks up due to attempting to synchronise with the running handler.
Fix this by using disable_irq_nosync().
Also make the same change in the recieve path.

...
The (relatively) new pmac_zilog driver doesn't use the pre-munged
IRQ numbers from the macio_dev unlike other macio things, it
directly maps it off the OF device-tree.
It does that because it can be initialized much earlier than the
registration of the macio devices, in order to get a serial
console early.
Unfortunately, that means that it "misses" some fixups done
by the macio layer to work around missing interrupt descriptions
in the device-tree of the Wallstreet machines.
This patch brings the necessary workaround into the pmac_zilog
driver itself to bring it back to working condition.

was enabled, but the console was directed elsewhere, udbg would not be
