Linus Torvalds db87114dcf - Explicitly disable the TSC deadline timer when going idle to address
some CPU errata in that area
 
 - Do not apply the Zenbleed fix on anything else except AMD Zen2 on the
   late microcode loading path
 
 - Clear CPU buffers later in the NMI exit path on 32-bit to avoid
   register clearing while they still contain sensitive data, for the
   RDFS mitigation
 
 - Do not clobber EFLAGS.ZF with VERW on the opportunistic SYSRET exit
   path on 32-bit
 
 - Fix parsing issues of memory bandwidth specification in sysfs for
   resctrl's memory bandwidth allocation feature
 
 - Other small cleanups and improvements
