Attached is the latest libata patch against 2.6.x mainline.  Although 
not 100% of content, most of this patch resolves around getting Silicon 
Image into better shape.  As I mentioned in my last post, this patch 
affects all libata users, so plenty of testing is requested.

Silicon Image-related changes:

* Only set/clear the BMDMA bits we care about (got a report last night 
this fixed 3114 for him)

* mask all SATA interrupts

* after determining drive speed, write that information to a special SII 
register Data Transfer Mode

* (style) make port base address setup a loop, shortening the code and 
making the code more readable

* limit SII to UDMA5 (reading info on FreeBSD lists and source code 
scared me about chip errata), mainly related to PATA->SATA bridges.
