Drew Galbraith 30bb10207e Add the Denali disk driver. 
Begin enumerating information from the PCI structure and HBA AHCI
structures.

Currently the PCI structure address is hardcoded but it should be
passed via a capability from the init process in the future.

This is a temp system call. Evemtually we should probably supply the

Drew Galbraith bd32e85164 Fix race condition in page fault handler. 
We enabled interrupts before getting the value of cr2 in the handler.
If the handler was preempted, cr2 could have been overriden by a page
fault in a separate thread or process.

Drew Galbraith add533071b Use APIC for interrupts rather than PIC. 
Still rely on the PIT for now rather than the local APIC timer.

Drew Galbraith 6c10c57bfa Mass rename memory object variables. 
Use shorthand:
AddressSpace -> vmas
MemoryObject -> vmmo

The VM prefix makes these a little more distinguishable in code.

Drew Galbraith e246f28d9c Get the second process elf from a MemoryObject instead of hardcoding. 
Allows us to delete the CopyIntoNonResidentProcess function and simply
rely on the MemoryObject copy functions.
