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.
