Because the way we were using inline assembly was technically incorrect
and breaking the laws of rust
This *finally* compiles. That doesn't mean it works!

Wrap borrows of page table entries in unsafe.
...
This is safe because `Entry` is `#[repr(8)]` which is the minimum
alignment for qwords. Since the size of a qword is equal to that
alignment (8), they can also be borrowed from the array.

Don't use the I/O APIC by default,
...
since this would require pcid to know the _PRT (PCI routing table) to
use and map the interrupt pins to the correct IRQs. xhcid is unaffected
by this though, since it uses MSI-X.
All ACPI handling will be done in userspace before the infrastructure
necessary would make sense (I don't think adding serde to the kernel
would be optimal, and how else would all of the ACPI namespace be
parsed?).
