 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.
