2009-05-07sh: Integrate the SH-5 onchip_remap() more coherently.Paul Mundt1-6/+0
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. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

2009-04-15[ARM] 5449/1: S3C: Use disable_irq_nosync() to fix boot lockupsMark Brown1-2/+2
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.

2009-04-07powerpc/pmac: Fix internal modem IRQ on Wallstreet PowerBookBenjamin Herrenschmidt1-0/+15
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.
