Where are Bookmarks synced in iOS6?

My iPad has some very dated bookmarks and I would like them to be in sync with my 27" i7 desktop iMac (Lion)

All the directions for syncing bookmarks talk about going into -
Settings > iCloud > Bookmarks on the iPad.

Problem is THIS DOESN'T EXIST!

I'm thinking things got changed in iOS6 - so where is the iMac/Safari to iPad bookmarks sync set up then?

Is it now the SAFARI parameter in Settings > iCloud > ????????

I tried turning that off and deleting the data and then turning it back on and syncing - it sort of works but I'm stlll getting something wrong with the bookmark set - it looks like a much older set of my Safari bookmarks - not the current set that's on my Mac/Safari.
