Grumble. I've seen better documented architectures out of Redmond.
Redo fabric evaluation to not use GET ALL NEXT (GA_NXT). Switches seem
to be trying to wriggle out of supporting this well. Instead, use
GID_FT to get a list of Port IDs and then use GPN_ID/GNN_ID to find the
port and node wwn. This should make working on fabrics a bit cleaner and
more stable.
This also caused some cleanup of SNS subcommand canonicalization so that
we can actually check for FS_ACC and FS_RJT, and if we get an FS_RJT,
print out the reason and explanation codes.
We'll keep the old GA_NXT method around if people want to uncomment a
controlling definition in ispvar.h.
This also had us clean up ISPASYNC_FABRICDEV to use a local lportdb argument
and to have the caller explicitly say that a device is at the end of the
fabric list.

time-of-day clocks, ported from NetBSD. The front-ends are expected
to be at least partly machine-dependent; the sparc64 EBus and SBus
ones will be commited to MD directories for now (in a subsequent commit).
a set of helper routines to deal with real-time clocks. The generic
functions access the clock diver using a kobj interface. This is intended
to reduce code reduplication and make it easy to support more than one
clock model on a single architecture.
This code is currently only used on sparc64, but it is planned to convert
the code of the other architectures to it later.

Also, added Sony, Lucent Embedded Ids and fix minor bugs for lucent
cards (and submit those changes back to ichiro-san)

PCPU_LAZY_INC() which increments elements in it for cases where we
can afford the occassional inaccuracy. Use of per-cpu stats counters
avoids significant cache stalls in various critical paths that would
otherwise severely limit our cpu scaleability.
Adjust all sysctl's accessing cnt.* elements to now use a procedure
which aggregates the requested field for all cpus and for the global
vmmeter.
The global vmmeter is retained, since some stats counters, like v_free_min,
cannot be made per-cpu. Also, this allows us to convert counters from
the global vmmeter to the per-cpu vmmeter in a piecemeal fashion, so
have at it!
most cases NULL is passed, but in some cases such as network driver locks
(which use the MTX_NETWORK_LOCK macro) and UMA zone locks, a name is used.

the generic lock type for use with witness. If this argument is NULL then
the lock name is used as the lock type. Add a macro for a lock type name
for network driver locks.
point to a more generic name for a lock that is more suitable for use by
witness when grouping locks. For example, although network driver locks
use the interface name for the name of each lock, they should all use the
same witness and be treated the same as witness. Another example is that
all UMA zone locks should be treated the same. The witness code has also
been updated to print out the lock type in addition to the lock name in a
few places where it is relevant.
This shrinks the size 4 bytes on alpha, down to the same 276 bytes
as all other platforms.
Construct a hack to make old ioctls work on new kernels.
Once world is recompiled only the new and correct sysctls will be
used.
This hack will become annoying around 1st of may to make people
rebuild their worlds and it will be gone before 5.0.
Andrew Korty's pam_ssh. The most notable difference is that this uses
commas rather than colons to separate items in the "keyfiles" option.

In the i386 case, options BOOTP requires options NFS_ROOT as well as
options NFSCLIENT. With *both* the NFS options, a bootpc_init()
prototype is brought in by nfsclient/nfsdiskless.h.
In the ia64 case, it just doesn't work and my change just pushes it
further away from working.

they aren't in the usual path of execution for syscalls and traps.
The main complication for this is that we have to set flags to control
ast() everywhere that changes the signal mask.
Avoid locking in userret() in most of the remaining cases.

inline function sigsetmasked() and a new macro SIGPENDING(). CURSIG()
will soon be moved out of the normal path of execution for syscalls and
traps. Then its efficiency will be less important but the new interfaces
will be useful for checking for unmasked pending signals in more places.
Submitted by: luoqi (long ago, in a slightly different form)
Assert that sched_lock is not held in CURSIG().
