[PATCH 0/4] drivers/ata: add another IRQ calls

Dear everyone.

This is the patchset (based on 2.6.20-rc4) for PATA controller
of Celleb. Now, I add two IRQ calls (irq_on, irq_ack) in
ata_port_operations. If these calls are not defined, ata_irq_on()
and ata_irq_ack() are used. Using them, the size of pata_scc.c
is reduced considerably.

I think the abstraction level of these calls are more acceptable
as libata I/F than low-level taskfile accessors.
Please give me any comments.

Best regards,
Akira Iguchi
