The outbsync one has further changes to come in the next batch to sort
out some platforms like PPC

Also fix the irq masking bug

This switches ide-dma to ide_execute_command and makes IDE DMA also happy
when running shared IRQ

This doesn't have the new -ac testing stuff from 2.4.21pre5-ac but it
has the stuff I now trust in it. This fixes the cache flush stuff and
also means ide-disk now should be safe shared IRQ

Dave Woodhouse did this a while ago and its been kicking around in my
tree just fine. This gets rid of a lot of the init lists of functions
still left in the kernel by having an __init type array built up for the
consoles as well

We must not look for a PCI IRQ for a non native mode IDE device
We must write PCI_INTERRUPT_LINE for VIA

ALi Magik requires workarounds for TV chips
IDE controllers require proper handling in legacy mode
PXB must be disabled on C0 450NX or the IDE will corrupt memory
VIA northbridge devices require the interrupt line is written
NEC_CBUS_2/3 require ISA DMA workarounds

This chip needs latency and other setups to avoid a PCI/AGP deadlock
with tv cards

The -ldb has to be at the end sometimes
