Series doesn't build after this patch because we lack the
apei_hest_func_t typedef:

  $ make drivers/acpi/apei/
    CC      drivers/acpi/apei/apei-base.o
  In file included from drivers/acpi/apei/apei-base.c:30:
  ./include/acpi/apei.h:36:21: error: unknown type name ‘apei_hest_func_t’
     36 | int apei_hest_parse(apei_hest_func_t func, void *data);
	|                     ^~~~~~~~~~~~~~~~

The kernel must build and function correctly after each and every
patch in the series.
