You may have seen discussion about kernel page table isolation (KPTI)
. These patches are now in the -rc6
kernel which is currently building for rawhide. I turned on the
feature as it's had a good amount of testing and review by now.
Some patches are also queued up for 4.14 so these will be
trickling into F26 and F27 as well per the usual stable cycle.
As always, please report bugs if you find them and let us know
if you have any questions.
Happy New Year!
