171b420b11 Bruce pointed out a bogon:
cur_console is NULL when copy_font() is first called from scinit().  This
is apparently harmless when scinit() is called early from sccninit() -
page 0 is apparently mapped r/w then, and 0->status contains suitable
garbage.  However, when there is a serial console, scinit() is first
called from scattach() when the page tables are completely initialized,
so the NULL pointer causes a panic.

6bed7e5140 Guard against the i8254 timer being uninitialzed if DELAY() is
called early for console i/o.  The timer is usually in BIOS mode
if it isn't explicitly initialized.  Then it counts twice as fast
and has a max count of 65535 instead of 11932.  The larger count
tended to cause infinite loops for delays of > 20 us.  Such delays
are rare.  For syscons and kbdio, DELAY() is only called early
enough to matter for ddb input after booting with -d, and the delay
is too small to matter (and too small to be correct) except in the
PC98 case.  For pcvt, DELAY() is not used for small delays (pcvt
uses its own broken routine instead of the standard broken one),
but some versions call DELAY() with a large arg when they unnecessarily
initialize the keyboard for doing console output.  The problem is
more serious for pcvt because there is always some early console
output.

Guard against the i8254 timer being partially or incorrectly
initialized.  This would have prevented the endless loop.

Should be in 2.2.

5131d64e0c Removed option EXTRAVNODES. All versions of FreeBSD-2.x have a sysctl
variable `kern.maxvnodes' which gives much better control over vnode
allocation than EXTRAVNODES (except in -current between 1995/10/28 and
1996/11/12, kern.maxvnodes was read-only and thus useless).

3b20426160 Add the ex driver (Intel EtherExpress Pro/10).
I have no idea if this works since I don't have one of the cards to test.
I also don't know what the LINT and GENERIC entries should look like,
so I just made up some values for now and left them commented out.

ab372207b2 Fixed botched tables:
- the operands for bt, bts, arpl and `enter' were reversed.
- btr was reported as bts (with the correct operand order).
- cmpxchg was misplaced.  It was misplaced differently in the
  comments.  It is misplaced differently again in the i486 manual.
  I put it where the i586 manual and gas say it is.
- fucompp was misplaced.
- the rr table for(s) some versions of fstp, fcom and fcomp was non-null.
  This caused some invalid opcodes to be reported as "" instead of as
  "<bad instruction>".
- the word and long versions of the fi* instructions were reversed.
- aaa and daa were reversed.

Fixed bugs involving unusual operand sizes:
- 32-bit registers weren't always forced for bswap or for moves to and
  from special registers.
- the operand sizes weren't reported for [l]call or [l]jmp.
- displacements weren't truncated mod 2^16 when the operand size was
  16-bit.
- too-large displacements and offsets were fetched, and too-large
  offsets were reported, when the operand size was 16-bit.
- sign extended immediate bytes were extended too far when the operand
  size was 16-bit.

Fixed bugs involving usual operand sizes:
- 8-bit source registers weren't forced for mov[sz]b[wl].
- 16-bit source registers weren't forced for mov[sz]w[wl].
- immediate bytes were sometimes reported as sign extended even for
  byte operations.  Same for immediate words in word operations.
- the immediate byte was not reported as sign extended for `push'.

Finished Pentium support:
- cpuid, cmpxchg8b and rsm were missing.

Finished i287 support:
- fneni, fndisi and fsetpm were missing.  These are harmless nops on
  later FPUs.

Improvements:
- report invalid opcodes 0xd6 and 0xf1 using .byte.  They are special
  in not causing invalid operand exceptions when executed.
- report the immediate byte for unusual aam and aad instuctions.
  Immediate bytes other than 0x0a always worked and are documented to
  work on Pentiums.

This code was sent to me by Bruce Evans, and seems to fix some
possible kernel panic in case of an execution error. It did not
cause any problems on my system, but I did never observe the
problem this patch is supposed to fix, anyway.

This patch is a NOP, unless the kernel is built with "options
USER_LDT", and doesn't affect the GENERIC kernel for this reason.

effbfcfdc6 Apparently, someone changed the gsc driver to allocate one big buffer
at device attach time, instead of allocating and freeing buffers as
necessary. But he or she forgot to remove the line that invalidated
the buffer when the device is closed. Therefore, after using the
device for the first time, the buffer was incorrectly invalidated and
that caused a page fault on the second, and subsequent uses.

d0aea04fe0 Let the VM system know that on certain arch's that VM_PROT_READ
also implies VM_PROT_EXEC.  We support it that way for now,
since the break system call by default gives VM_PROT_ALL.  Now
we have a better chance of coalesing map entries when mixing
mmap/break type operations.  This was contributing to excessive
numbers of map entries on the modula-3 runtime system.  The
problem is still not "solved", but the situation makes more
sense.

Eventually, when we work on architectures where VM_PROT_READ
is orthogonal to VM_PROT_EXEC, we will have to visit this
issue carefully (esp. regarding security issues.)
