    To pick up the changes in:
    
      6650cdd9 ("x86/split_lock: Enable split lock detection by kernel")
    
      Warning: Kernel ABI header at 'tools/arch/x86/include/asm/msr-index.h' differs from latest version at 'arch/x86/include/asm/msr-index.h'
      diff -u tools/arch/x86/include/asm/msr-index.h arch/x86/include/asm/msr-index.h
    
    Which causes these changes in tooling:

    Now one can do:
    
    	perf trace -e msr:* --filter=msr==IA32_CORE_CAPS
    
    or:
    
    	perf trace -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'
    
    And see only those MSRs being accessed via:
    
      # perf trace -v -e msr:* --filter='msr==IA32_CORE_CAPS || msr==TEST_CTRL'
      New filter for msr:read_msr: (msr==0xcf || msr==0x33) && (common_pid != 8263 && common_pid != 23250)
