5fbc98d240 Add an instruction group break after the move to application register
and the move to control register to avoid dependency violations when
these functions are used. Note that explicit data and instruction
serialization also need to be in a subsequent instruction group.
This too requires that we have an igrp break here.

1247b1a9af Enable the high FP registers when we call the FPSWA handler and disable
them again afterwards. This fixes a disabled FP fault while in the FPSWA
handler.
While here, merge the FP fault and FP trap handling code to reduce code
duplication. Where code was different, it was not sure it should be.

Trigger case: ports/math/atlas

768ae8ea9a o Remove namespace pollution from param.h:
-  Don't include ia64_cpu.h and cpu.h
   -  Guard definitions by  _NO_NAMESPACE_POLLUTION
   -  Move definition of KERNBASE to vmparam.h

o  Move definitions of IA64_RR_{BASE|MASK} to vmparam.h
o  Move definitions of IA64_PHYS_TO_RR{6|7} to vmparam.h

o  While here, remove some left-over Alpha references.

a0ecb2ad9b * Various fixes to breakage introduced by the atomic and mutex reorgs.
* Fixes to the signal delivery code. Not quite right yet.

I would have preferred to wait until I have signal delivery actually
working but the current kernel in CVS doesn't build.

345b5e7cc0 Implement a rudimentary interrupt handling system which should be good
enough for clock interrupts in SKI.

f610b17c8d * Add rudimentary DDB support (no kgdb, no backtrace, no single step).
* Track recent changes to SWI code.
* Allocate RIDs for pmaps (untested).
* Implement assembler version of cpu_switch - its cleaner that way.

5135c38a27 Next round of fixes to the ia64 code. This includes simulated clock and
disk drivers along with a load of fixes to context switching, fork
handling and a load of other stuff I can't remember now. This takes us as
far as start_init() before it dies. I guess now I will have to finish off
the VM system and syscall handling :-).

fdfd00f78b Next round of ia64 work, including fixes to context switching,
implementing cpu_fork(), copy*str(), bcopy(), copy{in,out}(). With these
changes, my test kernel reaches the mountroot prompt.

263f9f6863 This is the first snapshot of the FreeBSD/ia64 kernel. This kernel will
not work on any real hardware (or fully work on any simulator). Much more
needs to happen before this is actually functional but its nice to see
the FreeBSD copyright message appear in the ia64 simulator.
