This meant that there were concerns that there might be serious issues attempting to use it on practical systems so it had a dependency on EXPERT added to warn people that it was in an early stage of development with very little practical testing. Since then things have moved on a bit. We have seen people testing on real hardware and now have people starting to produce some platforms (the most prominent being the 96boards Cello) which only have ACPI support and which build and run to some useful extent with mainline. This is not to say that ACPI support or support for these systems is completely done, there are still areas being worked on such as PCI, but at this point it seems that we can be reasonably sure that ACPI will be viable for use on ARM64 and that the already merged support works for the cases it handles. For the AMD Seattle based platforms support outside of PCI has been fairly complete in mainline a few releases now. This is also not to say that we don't have vendors working with ACPI who are trying do things that we would not consider optimal but it does not appear that the EXPERT dependency is having a substantial impact on these vendors. Given all this it seems that at this point the EXPERT dependency mainly creates inconvenience for users with systems that are doing the right thing and gets in the way of including the ACPI code in the testing that people are doing on mainline. Removing it should help our ongoing testing cover those platforms with only ACPI support and help ensure that when ACPI code is merged any problems it causes for other users are more easily discovered.
