Linus Torvalds d410b62e45 - AMD's automatic IBRS doesn't enable cross-thread branch target 
injection protection (STIBP) for user processes. Enable STIBP on such
   systems.
 
 - Do not delete (but put the ref instead) of AMD MCE error thresholding
   sysfs kobjects when destroying them in order not to delete the kernfs
   pointer prematurely
 
 - Restore annotation in ret_from_fork_asm() in order to fix kthread
   stack unwinding from being marked as unreliable and thus breaking
