I expect separate patches should now be patched against
acpica when possible?
Does this also make sense with patches which have dependencies
to other patches for the Linux kernel? In this case there is not a
"does not compile" dependency, but at least they belong together.
I wonder what works out for acpica and Linux kernel maintainers best,
please advise.
