ACPICA commit f0c4a06f1dfc4886d4e0c2aa30bc57b10c5a8c53

Like many tables, this is a header followed by multiple subtables of
varying self-identifying types, and ACPICA does not normally add a field
for the subtables, instead relying on pointer arithmetic past the end of
the first header struct, since indexing a flexible array member is
meaningless for variable-length entries. If we really wanted a field for
this, we could use a u8 flexible array member, but it contradicts the
current style. Using void *, however, is categorically wrong, as ACPI
tables never contain native C-language pointers.
