0b27d7104f Make PMAP_SHPGPERPROC tunable. One shouldn't need to recompile a kernel
for this, since it is easy to run into with large systems with lots of
shared mmap space.

49f854f926 - Do not handle the per-CPU containers in mbuf code as though the cpuids
were indices in a dense array. The cpuids are a sparse set and treat
  them as such, setting up containers only for CPUs activated during
  mb_init().

- Fix netstat(1) and systat(1) to treat the per-CPU stats area as a sparse
  map, in accordance with the above.

This allows us to properly boot with certain CPUs disactivated. However, if
we later decide to re-activate said CPUs, we will barf until we decide to
implement CPU spinon/spinoff callback hooks to allow for said CPUs' per-CPU
containers to get configured on their activation.

362c5c1e02 You were knocked senseless by the Boomerang, spun around by the Cyclone,
blown over by the Hurricane and had a house dropped on you by the Tornado.
Now it's time to have your parade rained on by... the Typhoon!

This commit adds driver support for 3Com 3cR990 10/100 ethernet
adapters based on the Typhoon I and Typhoon II chipsets. This is actually
a port of the OpenBSD driver with many hacks by me.

No Virginia, there isn't any support for the hardware crypto yet. However
there is support for TCP/IP checksum offload and VLANs.

Special thanks go to Jason Wright, Aaron Campbell and Theo de Raadt for
squeezing enough info out of 3Com to get this written, and for doing
most of the hard work.

Manual page is included. Compiled as a module and included in GENERIC.

3ad234d4ef swtch.s: During context save, use the correct bit mask for clearing
the non-reserved bits of dr7.

         During context restore, load dr7 in such a way as to not
         disturb reserved bits.

machdep.c: Don't explicitly disallow the setting of the reserved bits
           in dr7 since we now keep from setting them when we load dr7
           from the PCB.

           This allows one to write back the dr7 value obtained from
           the system without triggering an EINVAL (one of the
           reserved bits always seems to be set after taking a trace
           trap).

9b5ad47fb7 Bring in dirhash, a simple hash-based lookup optimisation for large
directories. When enabled via "options UFS_DIRHASH", in-core hash
arrays are maintained for large directories. These allow all
directory operations to take place quickly instead of requiring
long linear searches. For now anyway, dirhash is not enabled by
default.

The in-core hash arrays have a memory requirement that is approximately
half the size of the size of the on-disk directory file. A number
of new sysctl variables allow control over which directories get
hashed and over the maximum amount of memory that dirhash will use:

  vfs.ufs.dirhash_minsize
    The minimum on-disk directory size for which hashing should be
    used. The default is 2560 (2.5k).

  vfs.ufs.dirhash_maxmem
    The system-wide maximum total memory to be used by dirhash data
    structures. The default is 2097152 (2MB).

The current amount of memory being used by dirhash is visible
through the read-only sysctl variable vfs.ufs.dirhash_maxmem.
Finally, some extra sanity checks that are enabled by default, but
which may have an impact on performance, can be disabled by setting
vfs.ufs.dirhash_docheck to 0.

6d03d577a5 Reorg vm_page.c into vm_page.c, vm_pageq.c, and vm_contig.c (for contigmalloc).
Also removed some spl's and added some VM mutexes, but they are not actually
used yet, so this commit does not really make any operational changes
to the system.

vm_page.c relates to vm_page_t manipulation, including high level deactivation,
activation, etc...  vm_pageq.c relates to finding free pages and aquiring
exclusive access to a page queue (exclusivity part not yet implemented).
And the world still builds... :-)

0cddd8f023 With Alfred's permission, remove vm_mtx in favor of a fine-grained approach
(this commit is just the first stage).  Also add various GIANT_ macros to
formalize the removal of Giant, making it easy to test in a more piecemeal
fashion. These macros will allow us to test fine-grained locks to a degree
before removing Giant, and also after, and to remove Giant in a piecemeal
fashion via sysctl's on those subsystems which the authors believe can
operate without Giant.

b29f9e40f5 A slightly more complete change to timeouts:
1. Add SA_IO_TIMEOUT as an option (4 minutes default) to cover reads,
writes, wfm, test unit ready.

2. Add internal SCSIOP_TIMEOUT (e.g., for mode sense) at 1 minute. This
should not require an option, but is cleaner to parameterize.
