e69c40d865 Include pio.h so that all those drivers that only include cpufunc.h
get the faster io macros/inline code rather than call the routines
in support.s

8db02de884 Added MCOUNT_ENTER and MCOUNT_EXIT macros to profile.h
Removed inb function since it's more correctly in pio.h

Copied write_eflags and read_eflags over from npx.c

(Some changes to the macros suggested by Bruce were not made at this
time since his suggestions probably apply to all the macros and
these inlined/macro definitions need a lot of cleaning up at some
point in the future.)

3443a7b245 Brought over from 1.1.5:
Fix from Bruce Evans. There were missing sets of parantheses:

1. The checks for the standard data selectors were botched, so %ss == 0
   and probably %cs == 0 were allowed.  A fix is enclosed.  The checks
   for the standard selectors could be omitted without losing anything
   since the standard selectors pass the valid_ldt_sel() tests.

4f683116b4 Added support for many more videomodes, including graphic modes up til
320x200 256col VGA. This is nessesary for the iBCS stuff to work right.
(And we get the benefit of more video modes). Uses the videocard BIOS
to optain mode tables.
Added a "green" saver, switches off the syncs for "green" monitors.

82a2eb57c0 Beginnings of support for loadable protocol domains. In particular,
don't hard-code netisr values in icu.s, but rather, use an array of
function pointers and set them all up in machdep.c for statically-linked
protocol families.  (This will eventually be done differently.)

f7d6afc696 Be more careful about dereferencing curproc, p_vmspace, and curpcb,
otherwise the machine will overflow the stack in a recursive fault loop
(causing the machine to spontaneously reboot because of the stack fault
that ultimately happens).

ab9678ac9d Get all the definitions from DEFS.h and not directly from asmacros.h
if KERNEL is not defined.  lib/msun/i387/*.S include asmacros.h to
get the definitions of ENTRY(), etc.  This is bogus since asmacros.h
is only supposed to give definitions suitable for the kernel.  The
current definitions for the kernel almost worked but are missing
the ".type" declarations.  This caused the linker to print warnings
about doubtful relocations for almost anything linked to libm[sun].

Uniformize name and use of idempotence identifier.

fe7bb84c74 Remove <machine/eflags.h> and all dependencies on it. eflags.h is just
the Mach/i386 version of the BSD/vax(?) <machine/psl.h>.  The Mach
version has slightly better names for many macros but is now out of
date and little used.  It was originally used even less (for spelling
PSL_T as EFL_TF in <machine/db_machdep.h>).

1) if_ie.c:
	Changed a printf and put a space in it. Formerly the "<3C507>"
	confused the syslog. He tried to see that as the priority to
	log that message.

2) isa_device.h:
	Changed the iobase variable from short to u_short. EISA
	Adresses can go up to 0xf000 and the sign extension doesn't
	look good in the probe output. Example:
	ep1 at 0xffff8000-0xffff8000f is not good :-), i like more a
	ep1 at 0x8000-0x8000f.

3) isa.c:

	later already an "ed" tagged on the end.

6605d9f3db 1. Make this idempotent.
2. Hack.

	Hack is to define RCSID() to null macro so that new msun stuff
	will compile.  This does NOT belong here, and I DON'T want it to
	stay, I just need to put this here for now to enable msun and we need
	to talk about what our RCSID story is supposed to be.  We talked about
	supporting RCSID() one day, and everyone seemed to like the idea
	reasonably well of making it a macro you could just no-op this way,
	but we never did anything.  Now I see that JTCs code has it and I'm
	loath to remove it or do anything until we've discussed it some more.

	Well, so how about it?  What's our story vis-a-vis RCSID() going to
	be?
