Hi Linus,

Inside:

* Addition of struct ide_tp_ops and struct ide_host.

* Rework of probing code to allow unloading of host driver modules.

* Dynamic allocation of ide_hwif_t instances.

* More work on generic ATAPI support from Borislav Petkov.

* Janitorial fixes from Darren Jenkins, Harvey Harrison
and Pavel Machek.

* Misc fixes/cleanups.

Please pull from:

master.kernel.org:/pub/scm/linux/kernel/git/bart/ide-2.6.git/

to receive the following updates:
