Hi Ben, Attached are the two kernel config patches rebased to the latest v4.18.6-1 Buster kernel.
0001-arm64-Use-default-of-CONFIG_ACPI_NFIT-m.patch 0002-arm64-Updates-for-ACPI-servers.patch Do you plan to merge these? If there is anything I can do to make things easier for you please let me know. -Geoff

Remove the arm64 specific setting and use the default of module build.
