Ah.. great.  Hope you enjoyed the vacation.  Can you please pull from
#tj-upstream?

 git://git.kernel.org/pub/scm/linux/kernel/git/tj/libata-dev.git tj-upstream
 http://git.kernel.org/?p=linux/kernel/git/tj/libata-dev.git;a=shortlog;h=tj-upstream

Nothing much.  Rafael's skip-spin-off patchset + Elias's small fix +
ATA_HORKAGE_ATAPI_MOD16_DMA + pata_of_platform irq fix.

Gwendal posted patches to enable FIS based switching when NCQ is
disabled on sata_mv but I think this should be put into separate
branch and stay in linux-next till Mark Lord comes back and reviews it
as I don't know much about the driver and don't know of anyone other
than Gwendal and Mark who do.

sata_nv detection problem is still not resolved.  I figured out
generic and ck804 but nf2/3 is still malfunctioning.  I asked for more
tests and am waiting for results.

Eh... I guess that's about it.  Enjoy your INBOX.  :-P
