  x86/paravirt: Have only one paravirt patch function (2021-03-11 20:11:09 +0100)

----------------------------------------------------------------
First big cleanup to the paravirt infra to use alternatives and thus
eliminate custom code patching. For that, the alternatives infra is
extended to accomodate paravirt's needs and, as a result, a lot of
paravirt patching code goes away, leading to a sizeable cleanup and
simplification. Work by Juergen Gross.

----------------------------------------------------------------
Juergen Gross (15):
      x86/alternative: Drop unused feature parameter from ALTINSTR_REPLACEMENT()
      x86/alternative: Merge include files
      static_call: Move struct static_call_key definition to static_call_types.h
      static_call: Add function to query current function
      x86/paravirt: Switch time pvops functions to use static_call()
      x86/alternative: Support not-feature
      x86/alternative: Support ALTERNATIVE_TERNARY
      x86/alternative: Use ALTERNATIVE_TERNARY() in _static_cpu_has()
      x86/paravirt: Add new features for paravirt patching
      x86/paravirt: Remove no longer needed 32-bit pvops cruft
      x86/paravirt: Simplify paravirt macros
      x86/paravirt: Switch iret pvops to ALTERNATIVE
      x86/paravirt: Add new PVOP_ALT* macros to support pvops in ALTERNATIVEs
      x86/paravirt: Switch functions with custom code to ALTERNATIVE
      x86/paravirt: Have only one paravirt patch function
