For P8 the priority of different threads has no effect unless the
relative priority register is programmed to tell the relative
scheduling weight of the different priorities.
We will now be programming the RPR to give 32x performance boost
to "high" priority threads relative to "low" priority. This
means that when a thread is waiting on another, and thus has low
priority, it will get 32x less dispatch cycles then the thread
it is waiting on.

The memory profiling tools sometimes encountered a condition where
the kernel stack was becoming corrupted. I tracked it down to the
winkle code storing the winkle-save state at the wrong end of the
stack. Moving the winkle-save area to the bottom of the stack,
which is where I originally intended it to go.
Also noticed that the task issuing the winkle was in "running"
state while waiting for the cores to come out of winkle. Ensure
that the kernel updates the task state with a non-running status
while we are waiting for winkle to complete.

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.

* Allow page allocation system call to force coalesce if a
contiguous block is unavailable. [long-term enhancement]
* Workaround lack of large contiguous memory for PageTable
test-cases, which require 256K, by allocating a VMM block.
This should be removed when story 43401 is implemented.
[short-term workaround]

* Debug tool for PageManager.
* Support PageMgr allocations of non-2^k size.
* Switch page-allocation to always be in kernel-mode.
While investigating issue 44511, I noticed two problesm with the
memory page allocator (PageManager). First, the allocator did
not support allocations of pages which were not a power of 2,
which would result in pages appearing to "leak". Second, in
situations where a large allocation was requested and there was
not a large chunk available, the allocation would enter a
live-lock condition where coalescing would never occur.
Switched the PageManager so that all allocations happen in
kernel space. This allows us to force memory-release operations
on the syscall path when we are out of memory and also put in
place a task_yield call which will allow coalescing to eventually
occur. Issue 44523 is suppose to fully resolve any of these
live-lock paths.

This code is currently unused, due to InitService not having the
payload address and the start_host_os IPL step being unimplemented.
For testing purposes the 'shutdown' call in initservice.C can be
changed to pass a non-zero base address (such as 256MB).

- 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.

This is required to reduce the memory footprint of the kernel
so we can fit within 2MB. This patch will cause (in simics)
all other cores/threads to execute a 'doze' instruction and
cease executing. In VBU, only 1 core will be active anyhow.
