9d146ac5d1 Activate SSE/SIMD. This is the extra context switching support that
we are required to do if we let user processes use the extra 128 bit
registers etc.

This is the base part of the diff I got from:
  http://www.issei.org/issei/FreeBSD/sse.html
I believe this is by:  Mr. SUZUKI Issei <issei@issei.org>
SMP support apparently by: Takekazu KATO <kato@chino.it.okayama-u.ac.jp>
Test code by: NAKAMURA Kazushi <kaz@kobe1995.net>, see
  http://kobe1995.net/~kaz/FreeBSD/SSE.en.html

I have fixed a couple of style(9) deviations.  I have some followup
commits to fix a couple of non-style things.

17bbfb5897 Add 'hwatch' and 'dhwatch' ddb commands analogous to 'watch' and

by the architecture and if there are enough registers to cover the

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.

Discussed on: -fs, -hackers

7197571105 Move vm_page_zero_idle() from machine-dependant sections to a
machine-independant source file, vm/vm_zeroidle.c.  It was exactly the

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.

than waste a file on .keepme.  This should also make people's built

0865563a93 - Add support for decoding syscall names. (Brought over from the new alpha
trace code that was brought over from NetBSD.)
- Check for "syscall_with_err_pushed" as the label prior to a syscall trap
  frame rather than "Xlcall_syscall" and "Xint0x80_syscall".  We don't
  have a valid trapframe during the short range of code that those two
  symbols now cover.
- Simplify db_next_frame() to avoid duplicating the code for the different
  trap frame types.

  the new alpha trace code.)
