I wonder what "DRM updates" and "DRM fixes" include.

DRM there refers to Direct Rendering Manager[0].

A few days ago the author those changes are listed under (Dave Airlie) was on the HN frontpage for his comments on an AMD RFC[1].

DRM in the context of the Linux kernel refers to the Direct Rendering Manager, a graphics component. If you want to see all the merge commits from Dave Airlie (the long descriptions of which include a list of commits), try https://git.kernel.org/cgit/linux/kernel/git/torvalds/linux....

Intel memory protection key support is nice. QEMU now also has support for emulation of pkeys, but naturally you can't use them with KVM/hw acceleration (because you don't have hardware to support them). This is generally enough for testing/designing, though. (The performance of memory protection keys will be important however, so it's not helpful to really determine that yet.)

That said, I'd suggest obviously building your own minimal kernel/chroot to do these tests, since the lack of KVM/available hardware makes emulation turn-around time fairly terrible for right now.
