Linus Torvalds 64ad946152 - Get rid of all the .fixup sections because this generates 
misleading/wrong stacktraces and confuse RELIABLE_STACKTRACE and
 LIVEPATCH as the backtrace misses the function which is being fixed up.
 
 - Add Straight Light Speculation mitigation support which uses a new
 compiler switch -mharden-sls= which sticks an INT3 after a RET or an
 indirect branch in order to block speculation after them. Reportedly,
 CPUs do speculate behind such insns.
 
 - The usual set of cleanups and improvements
