a96255b62d Use 'pause' in several places rather than trying to tsleep() on NULL (which
triggers a KASSERT) or local variables.  In the case of kern_ndis, the
tsleep() actually used a common sleep address (curproc) making it
susceptible to a premature wakeup.

37e80fcac2 Add a new kernel sleep function pause(9). pause(9) is for places that
want an equivalent of DELAY(9) that sleeps instead of spins.  It accepts
a wmesg and a timeout and is not interrupted by signals.  It uses a private
wait channel that should never be woken up by wakeup(9) or wakeup_one(9).

0b989078d7 MFp4 (114068):
Use bus_get_dma_tag() to obtain the parent DMA tag to make the drivers
        a little bit more non-ia32/amd64 friendly.

        There is no man page for bus_get_dma_tag, so this is modelled after
        rev. 1.62 of src/sys/dev/sound/pci/es137x.c by marius.

ffcf6651a0 Use the new xpt_rescan function to truly now have dynamic
attachment of new devices that arrive (and we notice them
via async Fibre Channel events). We've always had the
right thing (of sorts) happen when devices go away- this
is the corollary function that makes multipath failover
actually work.

9e6461a2d8 Add an xpt_rescan function and a thread that will field
rescan requests. The purpose of this is to allow a SIM
(or other entities) to request a bus rescan and have it
then fielded in a different (process) context from the
caller.

There are probably better ways to accomplish this, but
it's a very small change that helps solve a number of
problems.

336b56124b There is a problem in setting/getting 'options'- if we check things
early, we haven't set board type, so we can't correctly check for
some options.  Fix this by splitting option setting/getting into
generic, pci and then later board specific, option setting/getting.

This was noticed when setting 'iid' (or 'hard loop id') didn't work
all of a sudden.

10fa77a3a9 If floppies are used to boot the machine, the user lets the machine
complete the boot and enter into sysinstall, and only then inserts
a CD into the CDROM drive and tries to select that as the install
media the first call to mount(2) generates EIO but the second call
to mount(2) will succeed.  This was 100% reproducible on 6.2-RELEASE,
RELENG_6, and HEAD.  If the user inserts the disc into the CDROM
while the machine is booting off the floppies the first call to mount(2)
succeeds with no problems.  The problem was originally reported in
PR #56952 against 5.1-CURRENT so it's been there for a while now.

a326064e24 Modify chunk_alloc() to prefer mmap()ed memory over sbrk()ed memory.
This has no impact unless USE_BRK is defined (32-bit platforms), in
which case user allocations are allocated via mmap() if at all possible,
in order to avoid the possibility of unreclaimable chunks in the data
segment.

Fix an obscure bug in base_alloc() that could have allowed undefined
behavior if an application were to use sbrk() in conjunction with a
USE_BRK-enabled malloc.

d05d46160a Use ETHER_BPF_MTAP() instead of BPF_MTAP() here. It's possible
incoming packets have had their 802.1Q tags processed by the
hardware, resulting in them being stripped from the packets, and
placed on the mbuf.  This fixes the processing of 802.1Q tags when
hardware offload of 802.1Q tags is enabled.

40d8a30241 Fix a bug in if_findmulti(), whereby it would not find (and thus delete)
a link-layer multicast group membership.
Such memberships are needed in order to support protocols such as
IS-IS without putting the interface into PROMISC or ALLMULTI modes.

sa_equal() is not OK for comparing sockaddr_dl as it has deeper structure
than a simple byte array, so add sa_dl_equal() and use that instead.

f7a66f06ec Restore support for the 5706C bce(4) phy that was broken during the
addition of SerDes support.  According to the docs, the 5706C and 5708C
phys are supposed to use the same MII model that is separate from the
SerDes parts, but the 5706C actually uses the MII model of the SerDes
parts.  To fix this, readd the old 5706C entry to miidevs and add a
special check in brgphy_probe() for phys that match the 5706C ID.  If
the phy is supported by the gentbi(4) driver, then it's a SerDes phy, so
we fail the probe and let gentbi(4) grab it.  Otherwise, it's a 5706C phy,
so we let brgphy(4) grab it.
