some of the IPI mechanisms used by the common MIPS SMP code so we could use
the multicast IPI facilities, on GXemul as well as on several real hardware
platforms, and the ability to have multiple hard IPI types.
o change rcname to kfd;
o move mandatory options to command_args;
o add missing "shutdown" keyword;
o fix require line. Kfd doesn't really need to be started before
daemons.

- DTrace scripts to check for errors, performance, ...
they serve mostly as examples of what you can do with the static probe;s
with moderate load the scripts may be overwhelmed, excessive lock-tracing
may influence program behavior (see the last design decission)
Design decissions:
- use "linuxulator" as the provider for the native bitsize; add the
bitsize for the non-native emulation (e.g. "linuxuator32" on amd64)
- Add probes only for locks which are acquired in one function and released
in another function. Locks which are aquired and released in the same
function should be easy to pair in the code, inter-function
locking is more easy to verify in DTrace.
- Probes for locks should be fired after locking and before releasing to
prevent races (to provide data/function stability in DTrace, see the
man-page of "dtrace -v ..." and the corresponding DTrace docs).
in the last import. They are sometimes needed when you want to use
advanced instructions.
Also, add clang's internal stdalign.h header to ObsoleteFiles.inc, since
it is redundant: we already have a stdalign.h header in /usr/include.

object for which digest_dynamic1() was not done yet. Just return
EINVAL and do not try to dereference NULL buckets hash array.
This seems to happen on ia64 for rtld object itself, where the
R_IA_64_FPTR64LSB relocations require symbol lookup. The dynamic
linker itself does not rely on identity of the C-level function
pointers (i.e. function descriptors).

I/O port addresses. Even if we do, this is hardly the place to mask
interrupts. It's not clear that this was at all needed. The code came
with CVS revision 1.2 of nexus.c when interrupt support was first added.
What is known is that ia64 has always been designed around the IOSAPIC,
and that doing I/O like this prevents Altix from booting.

for failure on malloc. Remove a couple of extra lines and remove
the spurious return.
