in df(1) when we have multiple filesystem types, and the complications of
handling UFS2 pushes this over the edge.
Use the .../mount/extern.h to get prototypes of the functions we
borrow from there. Constify things to match. (why aren't these
functions in a lib anyway ?)
Make everything static and set WARNS?=5.
The way the "df diskdevice" thing works for unmounted diskdevices
is not very general.

via INCS. Implemented INCSLINKS (equivalent to SYMLINKS) to
handle symlinking include files. Allow for multiple groups of
include files to be installed, with the powerful INCSGROUPS knob.
Documentation to follow.
Added standard `includes' and `incsinstall' targets, use them
in Makefile.inc1. Headers from the following makefiles were
not installed before (during `includes' in Makefile.inc1):
kerberos5/lib/libtelnet/Makefile
lib/libbz2/Makefile
lib/libdevinfo/Makefile
lib/libform/Makefile
lib/libisc/Makefile
lib/libmenu/Makefile
lib/libmilter/Makefile
lib/libpanel/Makefile
Replaced all `beforeinstall' targets for installing includes
with the INCS stuff.
Renamed INCDIR to INCSDIR, for consistency with FILES and SCRIPTS,
and for compatibility with NetBSD. Similarly for INCOWN, INCGRP,
and INCMODE.
Consistently use INCLUDEDIR instead of /usr/include.
gnu/lib/libstdc++/Makefile and gnu/lib/libsupc++/Makefile changes
were only lightly tested due to the missing contrib/libstdc++-v3.
I fully tested the pre-WIP_GCC31 version of this patch with the
contrib/libstdc++.295 stuff.
These changes have been tested on i386 with the -DNO_WERROR "make
world" and "make release".
default of -fguess-branch-probablility causes time optimizations (?)
like rewriting `if (foo) x++;' as
`if (!foo) goto forth; back: ; ...; forth: x++; goto back;". This is
pessimizes space especially well on i386's because one short branch
gets converted to 2 long ones.
Removed -fno-align-foo since it is implied by -Os. Previous commit
messages seem to have overstated the new alignment bugs in gcc. The
only case that affects boot2 is that -fno-align-functions (or
equivalently -falign-functions=1) actually gives -falign-functions=2.
This is caused by FUNCTION_BOUNDARY being 2 (bytes) instead of 1.
The default case where the optimization level is 1 and no alignment
options are given is more broken. All alignments are minimal, modulo
the bug in FUNCTION_BOUNDARY. This is caused by toplev.c setting
defaults too early.
Some hacks in previous commits ar not needed now, but may as well be
kept until gcc is fixed. The previous on in the Makefile saved 96
bytes of text due to the wrong FUNCTION_BOUNDARY and 32 bytes of data
due to unrelated bloat in the alignment of large objects. There aren't
even any options to control alignment of data.
before rev 1.229 (~ 100 ms). According to bde, some (old) broken
hardware could require it. In order to make timing more accurate than
what could be achieved with a loop around DELAY(1), increase loop
timing after the initial ~ 1 ms.
Also, move the declaration of FDSTS_TIMEOUT out from fdreg.h into fd.c
where it actually belongs to.

function to return the total number of CPUs and not the highest
CPU id.
o Define mp_maxid based on the minimum of the actual number of
CPUs in the system and MAXCPU.
o In cpu_mp_add, when the CPU id of the CPU we're trying to add
is larger than mp_maxid, don't add the CPU. Formerly this was
based on MAXCPU. Don't count CPUs when we add them. We already
know how many CPUs exist.
o Replace MAXCPU with mp_maxid when used in loops that iterate
over the id space. This avoids a couple of useless iterations.
o In cpu_mp_unleash, use the number of CPUs to determine if we
need to launch the CPUs.
o Remove mp_hardware as it's not used anymore.
o Move the IPI vector array from mp_machdep.c to sal.c. We use
the array as a centralized place to collect vector assignments.
Note that we still assign vectors to SMP specific IPIs in
non-SMP configurations. Rename the array from mp_ipi_vector to
ipi_vector.
o Add IPI_MCA_RENDEZ and IPI_MCA_CMCV. These are used by MCA.
Note that IPI_MCA_CMCV is not SMP specific.
o Initialize the ipi_vector array so that we place the IPIs in
sensible priority classes. The classes are relative to where
the AP wake-up vector is located to guarantee that it's the
highest priority (external) interrupt. Class assignment is
as follows:
class IPI notes
x AP wake-up (normally x=15)
x-1 MCA rendezvous
x-2 AST, Rendezvous, stop
x-3 CMCV, test
vm_object_deallocate(), replacing the assertion GIANT_REQUIRED.
o Remove GIANT_REQUIRED from vm_map_protect() and vm_map_simplify_entry().
o Acquire and release Giant around vm_map_protect()'s call to pmap_protect().
Altogether, these changes eliminate the need for mprotect() to acquire
and release Giant.

timed out while transmitting or receiving a file or if the file did
not exist, etc.

Savecore likes the results, but I have no way to test it as gdb is
still broken.
to 4 bytes free. I removed a printf (the Keyboard yes/no) since it is of
marginal value and sed'ed the generated asm output to remove the unwanted
aligns. There's probably a better way to gain a few extra bytes than
losing the printf. Shortening strings is probably a better option but this
should get us over the hurdle.
than the first one on a controller, and work for secondary
controllers.
Due to the prom not having nodes for each disk, but a catch-all one,
we have to iterate over each device, trying to open it to determine
whether it is actually present.
Since probing this way takese some time (and spews some spurious
warnings), it should maybe be short-circuited if we use the
device we were booted from.
Implement lazy device probing, and correct slice/partiniton
handling in the ofwd_open() code. With this, I can now actually boot
a kernel from disk, and the loader does not create unnecessary
delays.
