Make di_blocks unsigned in UFS1 as is the case already for UFS2.
Most of the code between UFS1 and UFS2 is shared so this change
is pretty safe. Not only this makes UFS1 and 2 consistent but it
also matches what NetBSD and MacOS X have for some years now.
UFS2: make di_extsize unsigned.
di_extsize is the EA size and as such it should be unsigned.

Add constants for use in interrogating various fiber and copper connectors
most often used with network interfaces.
The SFF-8472 standard defines the information that can be retrieved
from an optic or a copper cable plugged into a NIC, most often
referred to as SFP+. Examples of values that can be read
include the cable vendor's name, part number, date of manufacture
as well as running data such as temperature, voltage and tx
and rx power.
Copious comments on how to use these values with an I2C interface
are given in the header file itself.

Implement extended LUN support. If PIM_EXTLUNS is set by a SIM, encode
the upper 32-bits of the LUN, if possible, into the target_lun field as
passed directly from the REPORT LUNs response. This allows extended LUN
support to work for all LUNs with zeros in the lower 32-bits, which covers
most addressing modes without breaking KBI. Behavior for drivers not
setting PIM_EXTLUNS is unchanged. No user-facing interfaces are modified.
Extended LUNs are stored with swizzled 16-bit word order so that, for
devices implementing LUN addressing (like SCSI-2), the numerical
representation of the LUN is identical with and without PIM_EXTLUNS. Thus
setting PIM_EXTLUNS keeps most behavior, and user-facing LUN IDs, unchanged.
This follows the strategy used in Solaris. A macro (CAM_EXTLUN_BYTE_SWIZZLE)
is provided to transform a lun_id_t into a uint64_t ordered for the wire.
This is the second part of work for full 64-bit extended LUN support and is
designed to a bridge for stable/10 to the final 64-bit LUN code. The
third and final part will involve widening lun_id_t to 64 bits and will
not be MFCed. This third part will break the KBI but will keep the KPI
unchanged so that all drivers that will care about this can be updated now
and not require code changes between HEAD and stable/10.

Fix a use-after-free node reference issue when waiting for a return
from a management frame transmission.
This bug is a bit loopy, so here goes.
The underlying cause is pretty easy to understand - the node isn't
referenced before passing into the callout, so if the node is deleted
before the callout fires, it'll dereference free'd memory.
The code path however is slightly more convoluted.
The functions _say_ mgt_tx - ie management transmit - which is partially
true. Yes, that callback is attached to the mbuf for some management
frames. However, it's only for frames relating to scanning and
authentication attempts. It helpfully drives the VAP state back to
"SCAN" if the transmission fails _OR_ (as I subsequently found out!)
if the transmission succeeds but the state machine doesn't make progress
towards being authenticated and active.
Now, the code itself isn't terribly clear about this.
It _looks_ like it's just handling the transmit failure case.
However, when you look at what goes on in the transmit success case, it's
moving the VAP state back to SCAN if it hasn't changed state since
the time the callback was scheduled. Ie, if it's in ASSOC or AUTH still,
it'll go back to SCAN. But if it has transitioned to the RUN state,
the comparison will fail and it'll not transition things back to the
SCAN state.
So, to fix this, I decided to leave everything the way it is and merely
fix the locking and remove the node reference.
The _better_ fix would be to turn this callout into a "assoc/auth request"
timeout callback and make the callout locked, thus eliminating all races.
However, until all the drivers have been fixed so that transmit completions
occur outside of any locking that's going on, it's going to be impossible
to do this without introducing LORs. So, I leave some of the evilness
in there.
Candidate for 10.0.
Fix the "am I a net80211 vap" check for bpf listeners.

For WARNS <= 3, change the clang warning flag -Wno-conversion to
-Wno-enum-conversion. In earlier clang versions (before 3.2), the
latter did not exist, and suppressing enum conversion warnings was
really the goal of this warning suppression flag.
This should enable the same kind of warning again as was fixed by
r259072 ("incompatible integer to pointer conversion passing 'Elf_Addr'
(aka 'unsigned int') to parameter of type 'void *'"), and which was only
emitted by gcc.

Going forward, if an MFC includes mergeinfo, it will need to be made to

The mergeinfo in HEAD is in a bad state from years of neglect and manual

Fix accounting for hw.realmem on the i386 and amd64 platforms.
sys/i386/i386/machdep.c:
sys/amd64/amd64/machdep.c:
The value reported by FreeBSD as "real memory" when booting
doesn't match what is later reported by sysctl as hw.realmem.
This is due to the fact that the value printed during the
boot process is fetched from smbios data (when possible),
and accounts for holes in physical memory. On the other
hand, the value of hw.realmem is unconditionally set to be
one larger than the highest page of the physical address
space.
Fix this by setting hw.realmem to the same value printed
during boot, this makes hw.realmem honour it's name and
account properly for physical memory present in the system.

In sys/netpfil/ipfw/ip_fw_nat.c:vnet_ipfw_nat_uninit() we call "IPFW_WLOCK(chain);".
This lock gets deleted in sys/netpfil/ipfw/ip_fw2.c:vnet_ipfw_uninit().
Therefore, vnet_ipfw_nat_uninit() *must* be called before vnet_ipfw_uninit(),
but this doesn't always happen, because the VNET_SYSINIT order is the same for both functions.
In sys/net/netpfil/ipfw/ip_fw2.c and sys/net/netpfil/ipfw/ip_fw_nat.c,
IPFW_SI_SUB_FIREWALL == IPFW_NAT_SI_SUB_FIREWALL == SI_SUB_PROTO_IFATTACHDOMAIN
and
IPFW_MODULE_ORDER == IPFW_NAT_MODULE_ORDER
Consequently, if VIMAGE is enabled, and jails are created and destroyed,
the system sometimes crashes, because we are trying to use a deleted lock.

(1) Take a GENERIC kernel config, and add options for: VIMAGE, WITNESS,

Only initialize some mutexes for the default VNET.
In r208160, sctp_it_ctl was made a global variable, across all VNETs.

in crashes if many jails are created.
