First, change sysinstall and the Makefile rules to not build the kernel
nlist directly into sysinstall now. Instead, spit it out as an ascii
file in /stand and parse it from sysinstall later. This solves the chicken-n-
egg problem of building sysinstall into the fsimage before BOOTMFS is built
and can have its symbols extracted. Now we generate the symbol file in
release.8.
Second, add Poul-Henning's USERCONFIG_BOOT changes. These have two
effects:
1. Userconfig is always entered, rather than only after a -c
(don't scream yet, it's not as bad as it sounds).
2. Userconfig reads a message string which can optionally be
written just past the boot blocks. This string "preloads"
the userconfig input buffer and is parsed as user input.
If the first command is not "USERCONFIG", userconfig will
treat this as an implied "quit" (which is why you don't need
to scream - you never even know you went through userconfig
and back out again if you don't specifically ask for it),
otherwise it will read and execute the following commands
until a "quit" is seen or the end is reached, in which case
the normal userconfig command prompt will then be presented.
How to create your own startup sequences, using any boot.flp image
from the next snap forward (not yet, but soon):
% dd of=/dev/rfd0 seek=1 bs=512 count=1 conv=sync <<WAKKA_WAKKA_DOO
USERCONFIG
irq ed0 10
iomem ed0 0xcc000
disable ed1
quit
WAKKA_WAKKA_DOO
Third, add an intro screen to UserConfig so that users aren't just thrown
into this strange screen if userconfig is auto-launched. The default
boot.flp startup sequence is now, in fact, this:
USERCONFIG
intro
visual
(Since visual never returns, we don't need a following "quit").

fix the only case where the tty struct is referenced without a prior
check for existance.
certain error conditions, it is possible for pages to be left allocated
in the object beyond it's end. It is generally bad practice to allocate
pages beyond the end of an object.
support LD_HINTS_VERSION_2 that has the ldconfig pathname stored in the
ld.so.hints file (ie: a new library can be installed and used without
needing to run ldconfig -m first)

divisor latch registers if the registers wouldn't change.
Use the default console cfcr setting while setting the divisor
latch registers for console i/o. Input may be messed up by
transiently changing the cfcr.
Use a usual cfcr setting while setting the divisor latch registers
in the probe. This shouldn't matter, but this is not the place to
test the UART's handling of 5 bit words.
Removed a stale devfs comment.
was always disabled because "pci.h" wasn't included. Now the configured
pci devices are listed and you can edit bogus flags for them.
Fixed bitrot in the disabled code. A used #include was removed and const
poisoning wasn't fixed.
Removed unused #include.
not resuming the NIC as required for transmit. Thanks to Alan Cox
<alc@cs.rice.edu> for noticing this.
Added another performance optimization to compensate. :-)
Changed crscdt to 1...strange, but this seems to be needed for some reason
despite what the manual says.

are more descriptive, and in the case of invlpg, a real opcode.
Additionally, fix the tlb management code for 386 machines.
- kern.maxproc and kern.maxprocperuid were read-only (and thus essentially
useless. Apparently no one uses them).
- all the user sysctls were read-write (and thus it was possible for them
to be inconsistent with the authoritative fixed values in the library).
Removed unused #include.
for headers in the compile directory work unsurprisingly. Without
-I-, the search for "foo.h" begins in the directory of the file
that includes it, and the compile directory is only searched because
`-I.' is in ${INCLUDES}.
Removed -I$S/sys from ${INCLUDES}. It was once necessary to find
things like "param.h" in $S/sys. Now <sys/param.h> is found in $S.
lcall 7,0 (ie: ldt slot 0) and lcall 0x87,0 (ldt slot 16, it's shifted

comparisons in the inb() and outb() macros. I decided that int args
are OK here. Any type that can hold a u_int16_t without overflow
is correct, and 32-bit types are optimal.
Introduced a few tens of warnings (100 in LINT) for use of pessimized
(short) types for the port arg. Only a few drivers are affected by
this. u_short pessimizations aren't detected.
Added `__extension__' before the statement-expression in inb() so
that it can be compiled without warnings by gcc -pedantic.
