0724f323cf Move the type definition of ointhand2_t from i386/include/types.h to
i386/isa/isa_device.h.  This is a more appropriate location and
helps restrict <machine/types.h> to only types that exist on all
platforms.

48d5c9ed0e Delay the creation of the ugenX device node until we're certain
that the attach succeeded.  (Fixes a potential panic for devices
that fail to attach properly and are subsquently unplugged and then
plugged back in again.)

770030e679 vm_page_queue_free_mtx is a spin mutex, not a normal sleep mutex.
I do not know why this didn't panic my box, but I have most certainly
been using it:

94af63d292 Turn the zeroidle process off for SMP systems, there is still a possible
TLB problem when bouncing from one cpu to another (the original cpu will
not have purged its TLB if the it simply went idle).

152cae690e Fix a bug caused by dereferencing an invalid pointer when
no punch_fw was used.
Fix another couple of bugs which prevented rules from being
installed properly.

On passing, use IPFW2 instead of NEW_IPFW to compile the new code,
and slightly simplify the instruction generation code.

c0b0dbd582 No functional changes, but:
Following Darren's suggestion, make Dijkstra happy and rewrite the
ipfw_chk() main loop removing a lot of goto's and using instead a
variable to store match status.

Add a lot of comments to explain what instructions are supposed to
do and how -- this should ease auditing of the code and make people
more confident with it.

In terms of code size: the entire file takes about 12700 bytes of text,
about 3K of which are for the main function, ipfw_chk(), and 2K (ouch!)
for ipfw_log().

7f6b47ac1c Add get/set param ioctl support.
Remove sim queue freezes for resource shortages. I've had too many
strange race conditions where I freeze on a resource shortage but
never get unfrozen.

Consolidate the remaining sim queue freeze condition (for loopdown)
into an inline with debug messages that allows us to track problems
at ISP_LOGDEBUG0 level easier. Change a bunch of debug messages about
loop down/up conditions to ISP_LOGDEBUG0 level.

Remove dead isp_relsim code.

Change some internal flag stuff for efficiency.

Complain vociferously if we try and use our FC scratch area while it's
busy being used already (I mean, if we don't have solaris' ability
to sleep as an interrupt thread which would allow us to just use
a p/v semaphore, at least *say* when you've just borked yourself).

Add infrastructure to allow overrides of hard loopid && initiator
id from boot variables.

Fix the usual quota of silly bugs:

 + 'ktmature' needs to be per-instance. Argh.
 + When entering isp_watchdog, set intsok to zero, preserving
   old value to restore later. It's not nice to try and sleep
   from splsoftclock.
 + Fix tick overflow buglet in checking timeout value.

8eccb6dabf Remove the 'bogus registrant' hack for fabric searches. It really
turns out that there's something of a hole in our new fabric name
server stuff.  We ask the name server for entities that have
registered as a specific type.  That type is FC-SCSI. If the entity
hasn't performed a REGISTER FC4 TYPES, the fabric nameserver won't
return it.

This brings this driver to a bit of a fork in the road as to what
the right thing to do is. For servicing the needs of accessing
FC-SCSI devices, this method is fine, and to be preferred. It is
extremely unlikely we're interested in fabric devices that *don't*
register correctly. If I ever get around to adding an FC-IP stack,
then asking for devices that have registers as FC-IP types is also
the right thing to do.

So- asking the fabric nameserver for a specific type is fine, *as
long as you are only interested in specific types*. If, on the other
hand, you want to create (as for management tool support) a picture
of everything on the fabric, this is *not* so fine. There are a
large class of FC-SCSI *initiators* who *don't* correctly register,
so we never will *see* them.

Is this a problem? Yes, but only a little one. If we want to do such
management tool support, we should probably run a *different* fabric
nameserver query algorithm. Better yet, we should talk to the management
nameserver in Brocade switches instead of the standard FC-GS-2 fabric
nameserver (which can be unwieldy).

Other changes: if we've overrrides marked, don't set some default
values from reading NVRAM. This allows us to override things like
EXEC throttle without having to ignore NVRAM entirely.

ebfda4c0dd Move __offsetof() macro from <machine/ansi.h> to <sys/cdefs.h>. It's
hardly MD, since all our platforms share the same macro.  It's not
really compiler dependent either, but this helps in reducing
<machine/ansi.h> to only type definitions.

62e40d1277 Add a special page zero entry point intended to be called via the single
threaded VM pagezero kthread outside of Giant.  For some platforms, this
is really easy since it can just use the direct mapped region.  For others,
IPI sending is involved or there are other issues, so grab Giant when
needed.

We still have preemption issues to deal with, but Alan Cox has an
interesting suggestion on how to minimize the problem on x86.

Use Luigi's hack for preserving the (lack of) priority.

Turn the idle zeroing back on since it can now actually do something useful
outside of Giant in many cases.

d67ae5f23f Fix a hideous TLB bug. pmap_unmapdev neglected to remove the device
mappings from the page tables, which were mapped with PG_G!  We could
reuse the page table entry for another mapping (pmap_mapdev) but it
would never have cleared any remaining PG_G TLB entries.

b73c441dad Collect all the (now equivalent) pmap_new_proc/pmap_dispose_proc/
pmap_swapin_proc/pmap_swapout_proc functions from the MD pmap code
and use a single equivalent MI version.  There are other cleanups
needed still.

While here, use the UMA zone hooks to keep a cache of preinitialized
proc structures handy, just like the thread system does.  This eliminates
one dependency on 'struct proc' being persistent even after being freed.
There are some comments about things that can be factored out into
ctor/dtor functions if it is worth it.  For now they are mostly just
doing statistics to get a feel of how it is working.
