      Pull perf fixes from Thomas Gleixner:
       "Another pile of fixes for perf:
      
         - Plug overflows and races in the core code
      
         - Sanitize the flow of the perf syscall so we error out before
           handling the more complex and hard to undo setups
      
         - Improve and fix Broadwell and Skylake hardware support
      
         - Revert a fix which broke what it tried to fix in perf tools
      
         - A couple of smaller fixes in various places of perf tools"

      MIPS: Initialise MAARs on secondary CPUs · e060f6ed
      Paul Burton authored
      MAARs should be initialised on each CPU (or rather, core) in the system
      in order to achieve consistent behaviour & performance. Previously they
      have only been initialised on the boot CPU which leads to performance
      problems if tasks are later scheduled on a secondary CPU, particularly
      if those tasks make use of unaligned vector accesses where some CPUs
      don't handle any cases in hardware for non-speculative memory regions.
      Fix this by recording the MAAR configuration from the boot CPU and
      applying it to secondary CPUs as part of their bringup.
