75b1f2d21c [zion] Store capability ids on the CapabilityTable. 
This is preferable to storing it in the capability itself since the id
is really just an index for the containing process.

242a18ae3c [zion] Finish cleaning up process capability interface. 
Make all functions generic and specify existing/vs new cap.

fc94bc5bf5 [zion] Update process interface to simplify capability insertion. 
Take a templated KernelObject with explicit permissions.

a47bac9966 [zion] Dynamically check Capability type. 
Instead of passing an enum with the capability when creating it, relying
on polymorphism and a template struct tag to determine the object type
at runtime.

This is cleaner and avoids errors where we pass the wrong capability
type with the cap and do a bad cast at runtime.

b4902a79ef [zion] Add per-process CapabilityTable object

4e328c2f7a Set RSP0 on context switch 
Previously we only set it on thread init which caused interrupts to
stomp on the stack of the most recently started thread, potentially
overwriting their cr3 and other variables and causing a crash.

e5da93757a Working AHCI DMA IPC from yellowstone to denali. 
We have a weird bug in context switching where a process's rsp0 ends up
pointing at the wrong value sometimes which crashes the OS.

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.

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.
