Merge remote-tracking branch 'remotes/ehabkost/tags/machine-next-pull-request' into staging

x86 and machine queue, 2020-09-02

Bug fixes:
* Revert EPYC topology patches that caused regressions
  (Babu Moger)
* Memory leak fixes (Pan Nengyuan)

QOM Cleanups:
* Fix typo in AARCH64_CPU_GET_CLASS
* Rename QOM macros for consistency and/or to avoid
  conflicts with other symbols
* Move typedefs to header files
* Correct instance/class sizes
