(just sent this upstream to Andrew and Linus)

This is libata push 1 of 3. This is largely the "accumulated driver
updates" push: lots of minor changes. A few new drivers.

The most notable thing is "devres", an optional subsystem for drivers
that greatly simplifies the task of driver housekeeping, if you have
to acquire+map then later unmap+free a bunch of MMIO resources,
some PIO resources, an IRQ (or two or three) like we do with ATA
host controllers. devres is only used by libata drivers at the moment,
but the APIs are generic enough to be used by any driver. This should
enable the elimination of several highly common code patterns in various
drivers.

devres, in turn, has enabled us to finally merge the patches that convert
libata to using the lib/iomap.c stuff. Anyone with eyes can see the
code savings in libata-sff that iomap brings.

Kudos to Tejun Heo for the devres work.

I will be pushing ACPI support on Saturday or Sunday, in order to stage
it into a separate 2.6.20-gitX snapshot. That's libata push 2 of 3.

The third push will eliminate the ugly split-driver configuration
created by quirk_intel_ide_combined() and ____request_resource(),
whereby libata claims one half of a controller (SATA), and old-IDE
claims the other half (PATA). libata wins the battle for DMA and IRQ,
and so old-IDE (PATA) is driven via the slower PIO data xfer methods.

Was necessary at the time, as libata lacked ATAPI support and old-IDE
failed to handle irq storms created by newer Intel IDE irq-ack behavior.
But times have changed, and neither conditions remain true. So we can
remove the hacks.
