6a025a98a6 Turn off and remove the 'old' if_ep ISA/EISA/PCCARD driver.
Turn on the 'new' if_ep driver which supports:

	ISA		3c509
	MCA		3c529
	EISA		3c579
	PCCARD		3c589

I think all we're missing is support for the VME bus and S-100 bus
Etherlink III cards.

The new code has been tested by a number of people and all the important
bits work.  I've not been able to test the EISA code but will do so once
my hardware arrives.  Since I've changed nothing in the EISA code I suspect
it will perform the same manner as before.

Future changes involve whacking the ISA and PCCARD front ends to use
newbus and to convert the driver to bus_space and make it use ifmedia.

This is the first working network driver that supports MCA bus devices btw.

Enjoy.

956d3333ca sigset_t change (part 4 of 5)
-----------------------------

The compatibility code and/or emulators have been updated:

iBCS2 now mostly uses the older syscalls. SVR4 now properly
handles all signals. This has been achieved by using the
new sigset_t throughout the emulator. The Linuxulator has
been severely updated. Internally the new Linux sigset_t is
made the default. These are then mapped to and from the
new FreeBSD sigset_t.

Also, rt_sigsuspend has been implemented in the Linuxulator.
Implementing this syscall basicly caused all this sigset_t
changing in the first place and the syscall has been used
throughout the change as a means for testing. It basicly is
too much work to undo the implementation so that it can
later be added again.

A special note on the use of sv_sigtbl and sv_sigsize in
struct sysentvec:
Every signal larger than sv_sigsize is not translated and is
passed on to the signal handler unmodified. Signals in the
range 1 upto and including sv_sigsize are translated.
The rationale is that only the system defined signals need to
be translated.

The emulators also have been updated so that the translation
tables are only indexed for valid (system defined) signals.
This change also fixes the translation bug already in the
SVR4 emulator.

91078fca0c sigset_t change (part 3 of 5)
-----------------------------

By introducing a new sigframe so that the signal handler operates
on the new siginfo_t and on ucontext_t instead of sigcontext, we
now need two version of sendsig and sigreturn.

A flag in struct proc determines whether the process expects an
old sigframe or a new sigframe. The signal trampoline handles
which sigreturn to call. It does this by testing for a magic
cookie in the frame.

The alpha uses osigreturn to implement longjmp. This means that
osigreturn is not only used for compatibility with existing
binaries. To handle the new sigset_t, setjmp saves it in
sc_reserved (see NOTE).

the struct sigframe has been moved from frame.h to sigframe.h
to handle the complex header dependencies that was caused by
the new sigframe.

NOTE: For the i386, the size of jmp_buf has been increased to hold
      the new sigset_t. On the alpha this has been prevented by
      using sc_reserved in sigcontext.

896f49b096 Newbusification of aha. dfr sent me the first cut, and I made it
work.  Be more verbose when one cannot allocate IRQ, et al since this
is a common configuration problem.  The cards have the IRQ soft wired
into their BIOS and do not try to do collision detection.  This can
cause problems when this IRQ is the same as another card/device.

The PNP hasn't been tested.  My PNP board is in a deployed system.
I'll sneak in testing of it sometime later.  I've been able to mount
the 3.3R cdrom that arrived today and access files off it.

ae8e1d08d7 This patch clears the way for removing a number of tty related
fields in struct cdevsw:

        d_stop          moved to struct tty.
        d_reset         already unused.
        d_devtotty      linkage now provided by dev_t->si_tty.

These fields will be removed from struct cdevsw together with
d_params and d_maxio Real Soon Now.

The changes in this patch consist of:

        initialize dev->si_tty in *_open()
        initialize tty->t_stop
        remove devtotty functions
        rename ttpoll to ttypoll

98a229f65e As suggested by phk, unconditionalize BPF support in these drivers. Since
there are stubs compiled into the kernel if BPF support is not enabled,
there aren't any problems with unresolved symbols. The modules in /modules
are compiled with BPF support enabled anyway, so the most this will do is
bloat GENERIC a little.

1088f6c7c1 Spruce up the ADMtek driver: conver to newbus, miibus and add support
for the AN985 "Centaur" chip, which is apparently the next genetation
of the "Comet." The AN985 is also a tulip clone and is similar to the
AL981 except that it uses a 99C66 EEPROM and a serial MII interface
(instead of direct access to the PHY registers).

Also updated various documentation to mention the AN985 and created
a loadable module.

I don't think there are any cards that use this chip on the market yet:
the datasheet I got from ADMtek has boxes with big X's in them where the
diagrams should be, and the sample boards I got have chips without any
artwork on them.

24514292fa On PIIX4 based SMP systems use the PMTMR register for timecounting.
It is about 2.5 microseconds or roughly 3 times faster to use this
"PIIX" timecounter than the "i8254" timecounter.  Resolution is
also 3 times better.

The code cheats and don't register the PCI device, because other pieces
of code want to use it too.

13ccadd4b0 This is what was "fdfix2.patch," a fix for fd sharing. It's pretty
far-reaching in fd-land, so you'll want to consult the code for
changes.  The biggest change is that now, you don't use
	fp->f_ops->fo_foo(fp, bar)
but instead
	fo_foo(fp, bar),
which increments and decrements the fp refcount upon entry and exit.
Two new calls, fhold() and fdrop(), are provided.  Each does what it
seems like it should, and if fdrop() brings the refcount to zero, the
fd is freed as well.
