Andy Lutomirski b185029f5c x86/speculation/mds: Improve CPU buffer clear documentation 
commit 9d8d0294e78a164d407133dea05caf4b84247d6a upstream.

On x86_64, all returns to usermode go through
prepare_exit_to_usermode(), with the sole exception of do_nmi().
This even includes machine checks -- this was added several years
ago to support MCE recovery.  Update the documentation.
