Make sure we read a likely value from the PIIX timecounter.
This should fix a large fraction of the "calcru: negative time"

as in NetBSD, but it has slightly different semantics (it already handles
incrementation of p->p_cpticks, and it should handle any calling frequency).

Add MD_ROOT and MD_ROOT_SIZE options to the md driver.
Make the md driver handle MFS_ROOT and MFS_ROOT_SIZE options for compatibility.
Add md driver to GENERIC, PCCARD and LINT.
This is a cleanup which removes the need for some of the worse hacks in
MFS: We really want to have a rootvnode but MFS on a preloaded image
doesn't really have one. md is a true device, so it is less trouble.
This has been tested with make release, and if people remember to add
the "md" pseudo-device to their kernels, PicoBSD should be just fine
as well. If people have no other use for MFS, it can be removed from
the kernel.
- Convert to new bus attachment scheme. Thanks to Blaz Zupan for doing
the initial work here. One thing I changed was to have the attach
and detach routines work like the PCI drivers, which means that in
theory you should be able to load and unload the driver like the PCI
NIC drivers, however the pccard support for this hasn't settled down
yet so it doesn't quite work. Once the pccard work is done, I'll have
to revisit this.
- Add device wi0 to PCCARD. If we're lucky, people should be able to
install via their WaveLAN cards now.
- Add support for signal strength caching. The wicontrol utility has
also been updated to allow zeroing and displaying the signal strength
cache.
- Add a /sys/modules/wi directory and fix a Makefile to builf if_wi.ko.
Currently this module is only built for the i386 platform, though once
the pccard stuff is done it should be able to work on the alpha too.
(Theoretically you should be able to plug one of the WaveLAN/IEEE ISA
cards into an alpha with an ISA slot, but we'll see how that turns out.
- Update LINT to use only device wi0. There is no true ISA version of
the WaveLAN/IEEE so we'll never use an ISA attachment.
- Update files.i386 so that if_wi is dependent on card.
parameter a char ** instead of a const char **. This make these
kernel routines consistent with the corresponding libc userland
routines.
Which is actually 'correct' is debatable, but consistency and
following the spec was deemed more important in this case.

we instead use 0(%esp), which is per-cpu, already pretty much
guarenteed to be locked into the cache, and does not stress the cache's
set associativity. invlpg might also be a good choice (suggested by
Ingo).

MP lock for the last time. The use of a locked instruction to
cpu-private memory is 3x faster then CPUID and 3x faster then the
use of a locked instruction to shared memory (the lock itself).
Instruction serialization is required to ensure that any pending
memory ops are properly flushed prior to the release of the lock,
due to out-of-order instruction execution by the cpu.
Since an osigcontext is smaller, if you check for a valid (much larger sized)
ucontext_t and it fails, we bogusly would reject the osigcontext as per
rev 1.378. Instead, check for osigcontext range validity first, and
ucontext_t later. This unbreaks Netscape.

- Add support for GUS and CS461x/428x pcm.
- Move newpcm drivers for ISA cards to files.i386. The drivers for

to use a locked cmpexg when unlocking a lock that we already hold, since
nobody else can touch the lock while we hold it. Second, it is not
necessary to use a locked cmpexg when locking a lock that we already
hold, for the same reason. These changes will allow MP locks to be used
recursively without impacting performance.
Modify two procedures that are called only by assembly and are already
NOPROF entries to pass a critical argument in %edx instead of on the
stack, removing a significant amount of code from the critical path
as a consequence.
