9d67e3dc28 Merge branch 'ioapic' into 'master' 
Support the I/O APIC alongside the 8259 PIC

9413475119 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?).

6a48ae3d8b Fix deadlock in sys: scheme 
This patch fixes a deadlock in the sys: scheme that is triggered
when the iostat resource() is called in the same scope where the RwLock
protecting the scheme's handles is write-locked.
