Use the new inline function in ia64_invalidate_icache().
While there, add proper synchronization so that we know
the fc.i instructions have taken effect when we return.
us to do the data serializations once after writing multiple
region registers, as is done in pmap_switch(). All existing
calls to ia64_set_rr() are followed with calls to ia64_srlz_d().

speculative loads. This at least makes control speculative loads
work. In the future we should analyze which faults/exceptions
we want to handle rather than defer to avoid having to call the
recovery code when it's not strictly necessary.
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.
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
- 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.
* 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.
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 :-).
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.
