File: ata-chipset.c     Status: Locally Modified

   Working revision:    1.126.2.22
   Repository revision: 1.126.2.22      /home/ncvs/src/sys/dev/ata/ata-chipset.c,v

File: ata-dma.c         Status: Locally Modified

   Working revision:    1.137.2.3
   Repository revision: 1.137.2.3       /home/ncvs/src/sys/dev/ata/ata-dma.c,v

Those revisions are logged as "MFC: Sync the -HEAD state of ata(4)
back to RELENG_6, except [ .. blahblah ..]"

I then applied, cleanly, sos@'s patch.


Best, Arno
