Intel SMAP Comes To Try To Better Secure Linux

[genstorm]

Eh, Michael, you missed to mention the most important things, on what hardware these are supported :P

To save others' googling: http://forums.grsecurity.net/viewtopic.php?f=7&t=3046

tl;dr SMEP came in Ivy and SMAP will come in Haswell.

Thanks for doing Michael's work and saving my time at that.

This SMEP and SMAP is it something that can be abused to prevent debugging, reverse engineering, memory inspection, decompilation?

Is it something that can be abused to implement DRM?
