- Add "Hardware Support" section and move device driver-related
items there.
- Move "Multimedia Support" and "Network Interface Support" into
the "Hardware Support" section as sub-sections.
- Move Netgraph-related items to "Network Protocols".
For translators: many items are moved but the contents
are not changed.
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).

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.
These normally only manifest if the ndis compat module is statically
compiled into a kernel image by way of 'options NDISAPI'.

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).
All of these changes are safe to MT5.
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).

Centralizing this stuff enables us to remove about 100 lines of

This is necessary so source upgrades use the correct binary.

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".
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.
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).
