The ARM_PROCESSOR_TABLE pseudo-ACPI table (which carries a ACPI-table like header but is published as a EFI config table) is not described in any relevant spec, and is not known to be relied upon by any OS. Let's just get rid of it. Signed-off-by: Ard Biesheuvel <ardb@kernel.org> Reviewed-by: Sami Mujawar <sami.mujawar@arm.com> Tested-by: Sami Mujawar <sami.mujawar@arm.com>
