Jeff?
Current patch is at http://www.kernel.org/pub/linux/kernel/people/jgarzik/libata/patch.iomap.bz2
I still merging stuff, so won't get around to it for another day or so :)
I certainly don't mind anyone stealing the task from me, but the effort is larger than the other iomap conversions. The patch above hits all the easily-picked fruit, leaving the stuff that requires a modicum of effort:
* map/unmap N PCI bars (N >= 4, per controller) * map/unmap 2 ISA I/O regions (0x170, 0x1f0) * accurately handle the odd situation where IDE driver steals 0x170 while libata steals 0x1f0 (or vice versa), a.k.a. the reason for quirk_intel_ide_combined() and the ____request_resource nastiness
Currently the code is set up to handle: * N PIO ports or * a single MMIO address that contains all the registers the driver needs (mmio_base)
