Hi Linus, This is the second pull, it has some changes to mm in it that should all have acks on them. The first dax constify arg patch got an ack on the list from Matthew Wilcox and Dan Williams after the MR was sent, but I didn't think it was worth a resend for that. This adds support for hugepages to TTM and has been tested with the vmwgfx drivers, though I expect other drivers to start using it.
