From: Tony Luck <tony.luck@xxxxxxxxx> ACPICA commit 52840d3826bd7e183fcb555e044e190aea0b5021 New MRRM tables can have subtables that are larger than 255 bytes. Add a new header typedef that uses u16 for Length. Could be backported to acpi_aspt_header, struct acpi_dmar_header, struct acpi_nfit_header, struct acpi_prmt_module_header, struct acpi_prmt_module_info. Will be used for upcoming ERDT table. MRRM table has a 26-byte reserved section in header. Add ACPI_DMT_BUF26 to describe this in struct acpi_dmtable_info.
