I'd agree as soon as someone can convince me that we actually want ACPI
support in the kernel for ARM64 servers. As far as I'm concerned it's quite
possible that the people who have worked on this for the past couple of
years behind closed doors know what they are doing and it will all be
good, but it's also possible that it turns into a huge trainwreck once
we see multiple implementations that have fundamentally incompatible
requirements regarding what they want from ACPI and we end up not doing
it at all. I just don't have enough information at this point to know which
of the two is true and I'd like to ensure that accepting the patches
that meet your criteria above would not be seen as an endorsement to do
crazy stuff later.
