If I understand what you want to do, you just have to do this :

$ git-checkout 2.6.18
$ git-pull . libata

This will merge in 2.6.18 everything that's in libata. If you
want to check before what will be merged :

$ git-log 2.6.18..libata
or :
$ git-diff 2.6.18..libata

or also to review the patches one at a time :

$ git-format-patch -k -m 2.6.18..libata

then read all the files.

Hoping it helps
