As CONFIG_ACPI depends on CONFIG_PM, then if you are able to end up
with a config having ACPI && !PM, then the Kconfig system is broken.
The brokeness is x86_64 specific, and results from the "select ACPI" below.
Please test if this single patch fixes all your multiple ACPI related build errors.
I fear, however, that this patch defeats the purpose of
b0bd35e622ffbda2c01dc67a0381c6a18817a29a -- which was to make selecting
NUMA more user-friendly. So it might make more sense to simply revert that
patch entirely.
The underlying problem is that Kconfig doesn't support using select
on targets which themselves have dependencies.
