#     Pull x86 fixes from Thomas Gleixner:
#      "A set of fixes for x86:
#     
#        - Make the AMD L3 QoS code and data priorization enable/disable
#          mechanism work correctly.
#     
#          The control bit was only set/cleared on one of the CPUs in a L3
#          domain, but it has to be modified on all CPUs in the domain. The
#          initial documentation was not clear about this, but the updated one
#          from Oct 2020 spells it out.
#     
#        - Fix an off by one in the UV platform detection code which causes
#          the UV hubs to be identified wrongly.
#     
#          The chip revisions start at 1 not at 0.
#     
#        - Fix a long standing bug in the evaluation of prefixes in the
#          uprobes code which fails to handle repeated prefixes properly.
#     
#          The aggregate size of the prefixes can be larger than the bytes
#          array but the code blindly iterated over the aggregate size beyond
#          the array boundary. Add a macro to handle this case properly and
#          use it at the affected places"
