A rounding error exposed by a new compiler caused us to write
over the SPTE entries for the extended memory block. This
led to unhandled page faults due to invalid permissions on the
affected pages.

Created per-node arrays of CPU objects rather than a single array
for the entire system. These are created dynamically as CPUs are
enabled.
Also disabled support for P7 due to the PIR layout being different
and hence would have needed two different sets of assembly code.
We have been running exclusively on the P8 Mambo model for a while.

- Changed overall page table behavior to no longer use C bits
in page table entries. Instead, individual blocks mark
pages as dirty based on stores during page faults. Initially
all writable pages are marked read-only until the first store
to it. At that time the block gets an exception and changes
the permission on the page table entry to writable and marks
its own SPTE to dirty.
- Greatly reduced the number of tlbie's and page table accesses.
Accomplished this by:
* Skipping many of the page table manipulations, such as
LRU updates, when the PTE is invalid.
* Converting most of the previously general-case of
"Modifying a PTE" to specific cases such as "Resetting
the Reference Bit" and "Modifying the SW field".
- Fixed the LRU-flush algorithm so that it is O(n) instead of
O(n^2), where n = size of page table.

- Add task_end2 syscall to allow pthread_exit-like retval.
- Add/maintain task states.
- Create task parent/child tracking tree.
- Add task_detach function.
- Implement wait syscalls.
Make task_exec caller the parent of spawned task:
Previously the task_exec call caused a message to the
VFS task, which called task_create and returned the tid
in response to the message. This causes the parent of
the spawned task to appear to be the VFS task.
Modify task_exec / VFS handling to instead return the
entry point address on the message and have task_exec call
task_create directly itself.
