at the moment (a lot of other code still needs to be changed), but
this seemed like a useful reference point to check in so that
others (i.e. Bill Fenner) have fair warning of where we are going.

swapgeneric.c hasn't had anything to do with swapping for some time.
It just makes the -a boot option actually work, and breaks the static
configuration of rootdev and dumpdev. It should be reorganized to
only support -a.

Thanks to Dave Huang <khym@bga.com> for reporting the problem
and suggesting a fix, though I chose a slightly different one.
- 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.

overflows and cause serious sign extension bug when large IDE HDD is

I believe this should be in 2.2.

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.
I want to have it in 2.2: it fixes a bug ...

code has been removed by optioning it out for now, so we can put it back
in ASAP if any problems are found.
and objects. Previously, "fancy" memory management techniques
such as that used by the M3 RTS would have the tendancy of chopping
up processes allocated memory into lots of little objects. Alan
has come up with some improvements to migtigate the sitution to
the point where even the M3 RTS only has one object for bss and
it's managed memory (when running CVSUP.) (There are still cases where the
situation isn't improved when the system pages -- but this is much much
better for the vast majority of cases.) The system will now be able
to much more effectively merge map entries.

nfs_sillyrename() self-destructs if you try to sillyrename a directory,
however nfs_rename() can be coerced into doing just that by the above
sequence of commands. To avoid this, nfs_rename() now checks that
v_type of the 'destination' vnode != VDIR before attempting the
sillyrename. The server correctly handles this particular situation
by returning ENOTEMPTY on the rename() attempt.
I asked if this was the correct fix for this on -hackers but nobody
ever answered.

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.
