- Simplify the logic by using __GNUC_PREREQ__.

- Make math.h compile with old (pre-8.0) versions of icc.

Commit patch to supress spurious link change events. Apparently, with
copper NICs, a link change event is posted whenever MII autopolling is
toggled off and on, which happens whenever someone calls
bge_miibus_readreg() or bge_miibus_writereg() to access the PHY
registers. This means anytime someone called the SIOCGIFMEDIA ioctl
on a bge interface, the link would reset. Even a simple "ifconfig bge0"
would do it, though other apps like dhclient or the PPPoE daemon could
trigger it as well. An obvious symptom of this problem is lots of
"bgeX: gigabit link up" messages appearing on the console for no
apparent reason.
Through experimentation, I determined that when a real link change
event occurs, the BGE_MIMODE_AUTOPOLL in the BGE_MI_MODE register
is always set, so now if we have a copper NIC and an link change
event occurs and the BGE_MIMODE_AUTOPOLL bit is clear, we ignore
the event.
Note that this does not apply to the original BCM5700 chip since we
use a different method for sensing link changes with that chip (the
status block method was broken), nor to fiber optic NICs since they
don't use the GMII PHY access registers.
Fix two ugly errors:
1. The correct cutoff for large uid/gid handling is 1<<18, not 1<<20.
2. Limit the uid/gid in the 'x' extension header (where numeric extensions
are not permitted) to 1<<18, but use the correct value in the regular
header (where numeric extensions are permitted).

Handle _FDE results of 5 bytes (vs. 5 uint32_t's). BIOS vendors find yet
another way to misinterpret the spec. Also, always fall back to the hints
probe on any attach failure, not just when _FDE fails.
Break out altq_enable/disable from DIOC{START,STOP}ALTQ into seprate
functions that can be called from enable/disable pf as well. This improves
switching from non-altq ruleset to altq ruleset (and the other way 'round)
by a great deal and makes pfctl act like the user would except it to.
- Make md(4) 64-bit clean.
After this change it should be possible to use very big md(4) devices.
- Clean up and simplify the code a bit.
- Use humanize_number(3) to print size of md(4) devices.
- Add 't' suffix which stands for terabyte.
- Make '-S' to really work with all types of devices.
- Other minor changes.
There is no need to keep 'npage' value inside our softc structure,
it is only used in one function. While doing so, change its type to
vm_ooffset_t.
We are still limited for swap-backed devices to 16TB on 32-bit architectures
where PAGE_SIZE is 4096 bytes.

Fix an out of bounds write during the initialization of the PF_INET protocol
family to the ip_protox[] array. The protocol number of IPPROTO_DIVERT is
larger than IPPROTO_MAX and was initializing memory beyond the array.
Catch all these kinds of errors by ignoring protocols that are higher than
IPPROTO_MAX or 0 (zero).

Ignore leading '_' in model name returned by devices.
This make "_NEC" devices appear as "NEC" which is more corrent.
The reason is tha NEC originally screwed up on the byteorder in the
model string, so now that they have realized that they prefixed the '_'
so that not every ATA driver on the planet would call them "EN C" :)
Reserve the DMA memory at attach time, rather than at use. While
reserving it at use time is more miserly, low memory (< 16MB)
evaporates quickly on many systems, so there may not be any suitable
buffers available. This specifically doesn't use the newer, fancier
isa_dma_init to ease merging to 5.
If the timeout handler runs and notices that commands are timed out, check
the firmware status register on the card to see if the firmware is still
running. There is no way to recover from this, but at least it can give
a hint as whether the car has crashed (which happens all too often).
For the moment, treat failures to attach floppy drives as non-fatal
errors for the attachment process for the floppy controller. This is
a band-aide because it doesn't try any of the fallback methods when
_FDE isn't long enough, but should be sufficient for people
experiencing the dreaded mutex not initialized panic.

Update path to c++ internals includes for the 3.4 location.

Remove the last two global variables that are used to store packet state while
it travels through the IP stack. This wasn't much of a problem because IP
source routing is disabled by default but when enabled together with SMP and
preemption it would have very likely cross-corrupted the IP options in transit.
The IP source route options of a packet are now stored in a mtag instead of the
global variable.
Clear all "active partition" bits before we set a new one.
This adds a safebelt that prevents users to mark more than
one "active" partitions, which will lead to a unbootable
machine, especially in multi-boot configurations.

Bring back etc/rc.d/ntpdate as requested by scads of people. This isn't a
complete backout as the ntpd_sync_on_start etc/rc.conf tunable is still
present, though the default is now NO (was YES). Since we're no longer
syncing time at startup by default when ntpd is enabled (as was the case
24hrs ago), remove UPDATING entry pointing out that ntpd(1) -g is slower
than ntpdate(1).
Hopefully ntpd_sync_on_start="YES" can be made the default for -CURRENT
after 5.3 is cut. At the very least, this should be set to YES when a
user requests to have ntpd enabled via sysinstall(1).
Make two major changes to this code to address some stability/corruption
problems:
1) Add locking for SMP, code provided by Alan Cox
2) While testing Alan's patches, I observed serious problems with
the jumbo buffer allocation code (machine crashed twice), so I gutted
it and rewrote the receive handler to use multiple chained descriptors.
Each RX descriptor gets a single 2K cluster, and the chip will fill in
as many as it needs to hold the complete packet.
User reports that this corrects the data corruption issues previously
observed and discussed on -current.
Note that this driver still needs to be hit with the busdma stick.
I intend to inflict said beating in the near future.
unlock global lock in kqueue_scan before msleep'ing to prevent dead
lock.. we didn't unlock global lock earlier to prevent just having
to reaquire it again..
Reactivate skipping over bogus IPCP addresses on ppp interfaces. Be more
careful with the skip condition this time. Addresses are only not taken into
account if:
- The interface is POINTTOPOINT
- There is no route installed for the address
- The user specified noalias (:0)
and - We are looking at an IPv4 address.
This should be enough paranoia to not cause any false positives.

o Allow for up to 3 resource I/O ranges to be given for the floppy
controller, rather than just two that are allowed for now.
o Make sure that we can work with either a base address of 0x3f0 or 0x3f2.
o Create new inline functions to access the YE DATA's unique BDCR register.
o Update pccard attachment to add the fd device.
o Do some minor style(9) polishing.
# I'm guessing that the fdc pccard attachment broke some time ago, since

Add 'hint.atkbd.0.flags="0x1"' back to /boot/device.hints on the
install media on i386 and amd64. While the current default is very
useful in server environments, the ability to use USB keyboards is
vastly more important then the ability to use PS/2 keyboards the admin
forgot to plug in during the install process.
Move pf* init from SI_SUB_PSEUDO to SI_SUB_PROTO_IFATTACHDOMAIN where it is
save to call if_attachdomain from if_attach() (as done for if_loop.c). We
will now end up with a properly initialized if_afdata array and the nd6
callout will no longer try to deref a NULL pointer.
Still this is a temp workaround and the locking for if_afdata should be
revisited at a later point.

Stop using ntpdate(1) in our startup procedure. Replace ntpdate(1) with
calls to ntpd -g. ntpd is noticeably slower than ntpdate, but is also more
accurate. This removes the nasty hackery in rc.d/ntpdate that would parse
out ntp servers from /etc/ntp.conf (ntpd knows how to read its own config
file). By default, ntpd *will* sync with its listed time servers. To
turn this off so that ntpd does not sync, ntpd_sync_on_start="NO" can be
added to /etc/rc.conf. If ntpd is not enabled (the default), then time is
not synced on startup. ntpdate has been depreciated by the ntpd authors
for quite some time so this change shouldn't be unexpected.
