#     Pull x86 and objtool fixes from Thomas Gleixner:
#      "A set of fixes for x86 and objtool:
#     
#       objtool:
#     
#        - Ignore the double UD2 which is emitted in BUG() when
#          CONFIG_UBSAN_TRAP is enabled.
#     
#        - Support clang non-section symbols in objtool ORC dump
#     
#        - Fix switch table detection in .text.unlikely
#     
#        - Make the BP scratch register warning more robust.
#     
#       x86:
#     
#        - Increase microcode maximum patch size for AMD to cope with new CPUs
#          which have a larger patch size.
#     
#        - Fix a crash in the resource control filesystem when the removal of
#          the default resource group is attempted.
#     
#        - Preserve Code and Data Prioritization enabled state accross CPU
#          hotplug.
#     
#        - Update split lock cpu matching to use the new X86_MATCH macros.
#     
#        - Change the split lock enumeration as Intel finaly decided that the
#          IA32_CORE_CAPABILITIES bits are not architectural contrary to what
#          the SDM claims. !@#%$^!
#     
#        - Add Tremont CPU models to the split lock detection cpu match.
#     
#        - Add a missing static attribute to make sparse happy"
