- caf 12y agoI believe SMAP makes UDEREF obsolete, at least on processors that support it.

- brynet 12y agoOpenBSD/amd64 does have SMEP/SMAP support, this was committed by Jonathon Gray (jsg@) in 2012, using QEMU. It's still hard to come by in actual hardware. http://freshbsd.org/search?project=openbsd&q=SMEP&committer=jsg http://freshbsd.org/search?project=openbsd&q=SMEP&committer=... http://freshbsd.org/search?project=openbsd&q=SMAP&ommitter=jsg http://freshbsd.org/search?project=openbsd&q=SMAP&ommitter=j...
