Which kernel is this patch supposed to be applied to?

Using current mainline (v2.6.35-rc3-262-g984bc96) the patch applies
without problems, but when I enable it in the kernel configuration I
get this:

Hi Wolfgang,

I took the mainline kernel v2.6.35-rc3 and downloaded using the git
download link.
I created the patch on 6/24/2010 after doing a git pull.

With the kernel tree on 6/24/2010 the driver compiled. I also tested the
functionality on the SATA drive & it worked.

Regards,
Rup

v2.6.35-rc3 was released on June 11, 13 days before 6/24/2010.

Can you please give the exact git commit ID so I can try reproducing
this?

I don;t think that you used v2.6.35-rc3; using this version, I still

It looks like -your- build config is missing CONFIG_ATA_SFF or similar.

If you actually look at include/linux/libata.h, you see that struct
ata_port_operations most definitely has a member named sff_check_status,
for example. Ditto ata_port and member ioaddr, etc.
