69acd21dfd Add support for the YE-Data external PCMCIA floppy driver. This
floppy is used on the toshiba Libretto line of subnotebook computers.
It differs from a normal floppy in that you must use PIO rather than
DMA to transfer the data.

To enable this, you must add options "FDC_YE" to your kernel.  I don't
have a machine that has a floppy and a pcmcia slot to test to make
sure that this doesn't impact normal floppy units, so I've left this as
an option.

I have ported this to -current and made an attempt to ensure that the
indentation conforms to style(9), aka the bruce filter.

57da30bfc9 linux_pipe does not preserve the edx register. Linux and
programs using glibc expect edx to be preserved accross syscalls.
As a result, linux programs running in emulation mode can
have whatever value may be represented by edx clobbered.

f7c9e34bea If there is no .depends file, use the standard ad-hoc way of ensuring
that the generated files are generated before any of the object files.
Also minor cleanup of dependencies in conf/files that I bogusly added
before.

This should fix the requirement that make depend be done starting from
a clean config directory.  If you don't have a clean directory, make
depend is still required if you want the proper .o's to be recompiled.

2127f26023 Examine all occurrences of sprintf(), strcat(), and str[n]cpy()
for possible buffer overflow problems. Replaced most sprintf()'s
with snprintf(); for others cases, added terminating NUL bytes where
appropriate, replaced constants like "16" with sizeof(), etc.

These changes include several bug fixes, but most changes are for
maintainability's sake. Any instance where it wasn't "immediately
obvious" that a buffer overflow could not occur was made safer.

726ff6a158 An early Christmas present: add driver support for a whole bunch of
PCI fast ethernet adapters, plus man pages.

if_pn.c: Netgear FA310TX model D1, LinkSys LNE100TX, Matrox FastNIC 10/100,
         various other PNIC devices

if_mx.c: NDC Communications SOHOware SFA100 (Macronix 98713A), various
         other boards based on the Macronix 98713, 98713A, 98715, 98715A
         and 98725 chips

if_vr.c: D-Link DFE530-TX, other boards based on the VIA Rhine and
         Rhine II chips (note: the D-Link and certain other cards
         that actually use a Rhine II chip still return the PCI
         device ID of the Rhine I. I don't know why, and it doesn't
         really matter since the driver treats both chips the same
         anyway.)

if_wb.c: Trendware TE100-PCIE and various other cards based on the
         Winbond W89C840F chip (the Trendware card is identical to
         the sample boards Winbond sent me, so who knows how many
         clones there are running around)

All drivers include support for ifmedia, BPF and hardware multicast
filtering.

Also updated GENERIC, LINT, RELNOTES.TXT, userconfig and
sysinstall device list.

I also have a driver for the ASIX AX88140A in the works.

9ad861edee - For some old Cyrix CPUs, %cr2 is clobbered by interrupts. This
problem is worked around by using an interrupt gate for the page
   fault handler.  This code was originally made for NetBSD/pc98 by
   Naofumi Honda <honda@kururu.math.sci.hokudai.ac.jp> and has already
   been in PC98 tree.  Because of this bug, trap_fatal cannot show
   correct page fault address if %cr2 is obtained in this function.
   Therefore, trap_fatal uses the value from trap() function.
-  The trap handler always enables interruption when buggy application
   or kernel code has disabled interrupts and then trapped.  This code
   was prepared by Bruce Evans <bde@FreeBSD.org>.

same preallocated local range (500-600) for blkdevs as well as cdevs,
just to be orthogonal.  The latter was for Brian, who has a *lot*
of local device drivers and needs more than just a single reserved
number.

d21c930ccb Fixed sloppy clearing of TS_BUSY. Don't clear it until the transmitter
is completely empty.  There is an interrupt for output completion.  It
is painful to use, but polling method used in the corresponding fix in
sio.c (rev.1.152) can't be used because there is no status bit for
transmitter-empty.  Now ttywait() works right.

976d09b9f2 Untangled the Cyclades offsets a little. CY16_RESET and CY_CLEAR_INTR
were half of their physical offsets for ISA and 1/4 of their physical
offsets for PCI, while all other Cyclades offsets were physical/1 for
ISA and physical/2 for PCI.  Logically wrong macros were used to scale
CY16_RESET and CY_CLEAR_INTR to the correct physical offsets.

Fixed some style bugs (mostly long lines).

c2906d55d0 Make timecounters more resistant to badly behaved SW/HW which locks
out interrupts for too long.  If you still see the "calcru: negative
time..." message you can increase NTIMECOUNTER (see LINT).

Sideeffect is that a timecounter is required to not wrap around in
less than (1 + delta) seconds instead of the (1/hz + delta) required
until now.

a84c84f5b0 Reduce i/o overheads by not preserving the channel access register in
interrupt handlers.  Instead, load and use it atomically as necessary.
This reduces mode switching overhead for "polled" mode interrupt handling
from 5 i/o's to 3 (per service type, per port) so that polled mode is only
slightly more inefficient than "interrupt" mode.

8280a33470 Deleted the workaround for lockup of certain (hopefully no longer used)
UARTs when their divisor latch registers are selected while they are
doing output.  Waiting for (some) output to drain is not permitted for
the TCSANOW case of tcsetattr().  NIST-PCTS easily detects bugs like
this by testing at at speeds that no one would want to use (50 bps).

Deleted stale comments related to flushing i/o.  Flushing works properly
for 16550s according to NIST-PCTS (it can't work properly for 16450s).
This finishes fixing all sio(16550)-related bugs found by NIST-PCTS.
