4c2efef4f7 * Turn off memory descriptor debugging - its served its purpose. 
* Don't get confused when memory regions don't lie on page boundaries -
  remember our page size is typically larger than the firmware's page size.
* Add a function ia64_running_in_simulator() which is intended to detect
  whether the kernel is running in SKI or on real hardware.

0fc343f1d8 - If we ever do the per-cpu KTR stuff, the index won't be volatile as it 
will be private to each CPU.
- Re-style(9) the globaldata structures.  There really needs to be a MI
  struct pcpu that has a MD struct mdpcpu member at some point.

4f7d5730b0 Rearrange so we search for I/O port space as early as possible (i.e. 
before console probing). Also fix a confusion between EFI's page size
which is fixed at 4096 and our own page size which is variable at compile
time.

d7abcfbcae Avoid the region used for thread0's trapframe when setting up the stack 
for ia64_init. If we use this area for ia64_init's stack, it ends up
containing garbage which causes cpu_fork to die horribly later.

f270e439ef * Use Intel's EFI headers instead of home-grown ones.

7b40715e82 * Enable dynamically linked kernel. This involves adding a self-relocator 
to locore to process the @fptr relocations in the dynamic executable.
* Don't initialise the timer until *after* we install the timecounter to
  avoid a race between timecounter initialisation and hardclock.
* Tidy up bootinfo somewhat including adding sanity checks for when the
  kernel is loaded without a recognisable bootinfo.

5596676e6c KSE Milestone 2 
Note ALL MODULES MUST BE RECOMPILED
make the kernel aware that there are smaller units of scheduling than the
process. (but only allow one thread per process at this time).
This is functionally equivalent to teh previousl -current except
that there is a thread associated with each process.

Sorry john! (your next MFC will be a doosie!)

ade9f272a1 * Make a start on a realistic definition for bootinfo.

96b9a12bd2 Rip some well duplicated code out of cpu_wait() and cpu_exit() and move 
it to the MI area.  KSE touched cpu_wait() which had the same change
replicated five ways for each platform.  Now it can just do it once.
The only MD parts seemed to be dealing with fpu state cleanup and things
like vm86 cleanup on x86.  The rest was identical.

XXX: ia64 and powerpc did not have cpu_throw(), so I've put a functional
stub in place.
