Remove an outdated assertion from _pmap_allocpte(). (When vm_page_alloc()
succeeds, the page's queue field is unconditionally set to PQ_NONE by
vm_pageq_remove_nowakeup().)
pass in pointer to m_head to re_encap because m_defrag could free the
original mbuf causing a free'd mbuf passed to bpf later and panic'ing the
system.. This should only effect jumbo frames.
Modify accept_fd_leak regression test to generate "PASS" output, not
just "FAIL" output, in order to make it consistent with other tests in
the regression test tree.
A long, long time ago in a CVS branch far away (specifically, HEAD prior
to 4.0 and RELENG_3), the BTX mini-kernel used paging rather than flat
mode and clients were limited to a virtual address space of 16 megabytes.
Because of this limitation, boot2 silently masked all physical addresses
in any binaries it loaded so that they were always loaded into the first
16 Meg. Since BTX no longer has this limitation (and hasn't for a long
time), remove the masking from boot2. This allows boot2 to load kernels
larger than about 12 to 14 meg (12 for non-PAE, 14 for PAE).

Provide our own FPSWA definitions, instead of depending on the Intel
EFI headers and put them all in <machine/fpu.h>. The Intel EFI headers
conflict with the Intel ACPI headers (duplicate type definitions), so
are being phased out in the kernel.
Fix compiler warnings, when __stdcall is #defined, by adding explicit casts.
These normally only manifest if the ndis compat module is statically
compiled into a kernel image by way of 'options NDISAPI'.
The early-adopter doesn't exist in HEAD anymore. The source is there,
but it's disconnected from the build. Remove it from the architecture
independent release documentation set, because it breaks "make release"
when NODOC is undefined.
The long dead hand of the past has pushed forward useless bits in this
driver. Trim its fingernails by removing some useless bits before
fixing the 'thread not terminated on detach' problem.
o dmacnt is no longer used now that we allocate at attach time. Remove
it from struct fdc_data.
o ISPNP was only ever set, but never tested. It used to be used for the
allocation routines to change how it allocated resources. Since that's
no longer necessary, retire the flag.
o ISPCMICA was only ever tested, but never set. GC it. This removes
a special case in determining the drive type. The drive type is
now set in fdc_pcmcia.c, so the hack isn't needed anymore. Sadly,
this isn't tested with a Y-E Data pcmcia floppy drive because there
are a number of other issues that preclude it from working.
o Fix ifdef for reading from the rtc. I'm of the opinion that this ifdef
should be moved into fdc_isa.c, but not today as ideally there'd be
other fixes to the probing of children. So now we just read it on
i386 ! pc98 (there's no #define for MACHINE_ARCH, just MACHINE, hence
this slightly inelegant kludge) and amd64. The PC98 exclusion likely
isn't meaningful since pc98 uses a different driver, but will be when
merging of the pc98 floppy code into this driver is complete (this is the
other reason I think this block of code belongs outside fdc.c).
Teach swap1 script how to remove added swap devices on system shutdown.
Without this change, if one had a swap-on-mirror configuration, gmirror
will rebuild mirror component(s) on boot, because they are dirty (they
were open on shutdown).
Pass the idea of the make(1) binary to use down to newvers.sh.

For the record: Problem spotted by Scott Long, who mentioned
that source upgrades from 4.7 to recent 5.x and 6.0 are broken.
Detailed analysis shows that 4.7 has a broken make(1) binary.
A breakage was fixed in RELENG_4 in make/main.c,v 1.35.2.7 by
imp@, though the commit log erroneously stated "MFC 1.68"
while in fact it should have been spelled as "MFC 1.67".
- Show all commands in usage, even if those commands are not available.
- When command is not available, just say it, instead of says, that command
is unknown. Old behaviour seems to be too confusing.

Further refine some #ifs:
- Simplify the logic by using __GNUC_PREREQ__.

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

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.
