The gist of the story is that an Intel vulnerability is requiring
OS vendors to institute Page Table Isolation in their kernels.
This fix has an _across the board_ 5-7% slowdown on Intel chips.
Worse yet, programs which do lots of syscalls will see around a
30% slowdown or more, including compilation.
AMD is not effected.
