sys/stdarg.h and expect compiler to provide proper builtins, defaulting
to the GCC interface. lint still has a special fallback.
Reduce abuse of _BSD_VA_LIST_ by defining __va_list by default and
derive va_list as required by standards.
for the assembler files, define the old names to the new names
since using the new names cause ugliness due to longer identifer
names, and reduces churn.
fixes build issues in dtv and vaguely makes <machine/psl.h> slightly
less name-space invasive.

divide each machine's bus.h into bus_defs.h (constants & data types)
and bus_funcs.h (macro implementations of bus_space(9) routines and MD
prototypes).
Note that some bus_space(9) routines' implementation will move to .c
files from inline subroutines or macros in .h files.
I've only made the split for machine architectures where there is PCI.
All of the non-PCI-having architectures will require a similar split.
These #include files are not referenced by any (committed) Makefiles or
header files, yet. Changes to Makefiles, to <sys/bus.h>, and to some
more machine-dependent files will dribble in before I throw the switch.
use the right names and avoid some array bounds violations picked up
by GCC 4.5. it's a real bug, but the code would have been generated
correctly for the sparc* ABIs.
- Reorganize locking in UVM and provide extra serialisation for pmap(9).
New lock order: [vmpage-owner-lock] -> pmap-lock.
- Simplify locking in some pmap(9) modules by removing P->V locking.
- Use lock object on vmobjlock (and thus vnode_t::v_interlock) to share
the locks amongst UVM objects where necessary (tmpfs, layerfs, unionfs).
- Rewrite and optimise x86 TLB shootdown code, make it simpler and cleaner.
Add TLBSTATS option for x86 to collect statistics about TLB shootdowns.
- Unify /dev/mem et al in MI code and provide required locking (removes
kernel-lock on some ports). Also, avoid cache-aliasing issues.
Thanks to Andrew Doran and Joerg Sonnenberger, as their initial patches
formed the core changes of this branch.
sp_dcache_flush_page() to help the smp version.
XXX: probably best to have usI/II and usIII (and nop) of this and
XXX: avoid the need for sp_dcache_flush_page at all.
we can set these to functions that simply return on sun4us/sun4v systems.
also include some work-in-progress #if 0'ed code to do the same for the
dcache_flush*() functions.
(some of these could probably move into the cpuinfo except that sparc64
systems don't really ever work with mismatches AFAICT.)
not the firmware console. While there get rid of some more code carried over
from macppc that doesn't work on sparc64 and consistently use node vs.
console_node.
property, and if set, use it instead of pfp.PortSCSIID.
on sparc64 systems on "scsi" or "scsi-2" devices, look from our node
up the tree for a "scsi-initiator-id" property, and if present, copy
it into the device properties.
this fixes mpt(4) issues on PRIMEPOWER250 (and probably other) systems.
idea from freebsd r207243/r207287, but reworked to use our device
properties instead of platform #ifdefs.
look in "device_type" as well as "name" for "ethernet" or "network",
and also look to see if a "local-mac-address" is set when choosing if
this may be a network device. fixes bge(4) nul ethernet address on
the same PRIMEPOWER250.
