fe0f2d4e11 Conditional acquisition of socket buffer mutexes when testing socket
buffers with kqueue filters is no longer required: the kqueue framework
will guarantee that the mutex is held on entering the filter, either
due to a call from the socket code already holding the mutex, or by
explicitly acquiring it.  This removes the last of the conditional
socket locking.

b3f1e85ab9 Pick up changes in rev 1.8 of src/sys/dev/ic/mpt_netbsd.c from NetBSD.
Set the DMA SGL length correctly if the DMA request must be chained because
it is too large to fit in one SGL.

This should fix this driver for some Dell Precision systems.

f1009e1e1f Commit Doug White and Alan Cox's fix for the cross-ipi smp deadlock.
We were obtaining different spin mutexes (which disable interrupts after
aquisition) and spin waiting for delivery.  For example, KSE processes
do LDT operations which use smp_rendezvous, while other parts of the
system are doing things like tlb shootdowns with a different mutex.

This patch uses the common smp_rendezvous mutex for all MD home-grown
IPIs that spinwait for delivery.  Having the single mutex means that
the spinloop to aquire it will enable interrupts periodically, thus
avoiding the cross-ipi deadlock.

e3e49f7e32 Until I can get a clearer architecture from PHK about why he wants
the geometry code to grab a mutex that prohibits any driver on the
stack below it from sleeping, it's not safe to allow anything in
the top half of isp to sleep (excepting the thread that Fibre Channel
instances use to re-scan loops/fabrics).

adad474471 Rework sysresource management. Instead of having each sysresource object
hold its own values, pass them up to the parent (acpi0) and merge/uniq them
on the way.  After the namespace evaluation, acpi will reserve these
resources and manage them via rman before bus_generic_probe() and
bus_generic_attach().  This is necessary because some systems specify
conflicting resources in separate sysresource objects.  It's also cleaner
in that the interface between sysresource and acpi is now merely the parent's
resource list.  This code handles the following cases:

1. Unique resource:  add it to the parent via bus_set_resource().
2. New wholly contained in old:  discard new.
3. New tail overlaps old head:  grow old head downward.
   AND/OR
4. New head overlaps old tail:  grow old tail upward.

c1466d61d9 My recent measurement shows that CPU_DISABLE_CMPXCHG is no longer necessary
with VmWare 4.x. At least with VmWare version 4.5.2, i386 version of
atomic_cmpset_int() is about 30 times slower than non-i386 version. It
makes this delta a good 5.3 MFC candidate, since otherwise it will
mislead users who run FreeBSD under modern VmWare otherwise.

c415679d71 Remove in6_prefix.[ch] and the contained router renumbering capability.
The prefix management code currently resides in nd6, leaving only the
unused router renumbering capability in the in6_prefix files.  Removing
it will make it easier for us to provide locking for the remainder of
IPv6 by reducing the number of objects requiring synchronized access.

This functionality has also been removed from NetBSD and OpenBSD.

c480dc188f Pass a correct lowaddr to bus_dma_tag_create(), lnc(4) cards can only
deal with 24-bit addresses.  While the two other attachments, namely
isa and cbus, do it properly, the PCI attachment was passing
BUS_SPACE_MAXADDR instead of BUS_SPACE_MAXADDR_24BIT.  This bug
became apparent with the new contigmalloc() code.

This fixes the problem reported with lnc(4) interfaces inside VMWare,
and should theoritically also fix any user of a PCI lnc(4) card.  It
is a RELENG_5 MFC candidate.

2bbb534b56 Move the cow field between wire_count and hold_count. This is the
position that is 64-bit aligned and makes sure that the valid and
dirty fields are also 64-bit aligned. This means that if PAGE_SIZE
is 32K, the size of the vm_page structure is only increased by 8
bytes instead of 16 bytes. More importantly, the vm_page structure
is either 120 or 128 bytes on ia64. These are "interesting" sizes.

2b004a226d When creating a new md, wait for geom's event queue to become empty
before returning.  Device nodes are created via the "taste" mechanism,
so this is necessary in order to make sure that devfs entries are
created before mdconfig(8) returns.

This may be a MFC candidate for 5.3.

bf5ab950e3 The new contigmalloc code is exposing a lot of misuses of busdma memory
allocation. Notably, in this case, the driver tries to allocate several
pieces of memory and then fails if the pieces allocated after the first
do not come after it physically, and within a specific range (8MB I
believe).  Of course, this could just as easily fail for any number of
reasons, but it almost always fails now that contiguous allocations start
at the end of possible specified memory locations rather than the beginning.

Allocate all the possibly-needed memory up front, even though it's a waste,
to get around this.  The least bogus solution would be to take the physical
address from the first allocation and create a new tag that specified that
further allocations must follow it within that 8MB window, then use that
when allocating new channels, but that's left for anyone else that really
feels like doing it.

fa1fc9094a Part 2 of fixing the boot code: gcc 3.4 fixes.
The whole problem seems to be size. Which is odd, because it is said
that size doesn't matter. Anyway... Add -Os to strategic places in the
makefile to have the final loader be as mall as possible. This seems
to be enough to make it work. For now... I think something is more
fundamentally wrong; or something more fundamental is wrong. Potato,
