On my "hardlink detection torture test", this reduced
user time from 4700 seconds down to 4.2 seconds
and wallclock time from 1:24:48 down to 1:08.
(Yes, that's over one THOUSAND times reduction in user time. ;-)
In the worst case, the new code doubles peak memory usage,
though it could actually reduce memory usage in many cases.

as dependent on binutils features/quirks as the current one. This one
loads plain .o files without having to mess with shared object mode.
This happens to be essential on amd64, because binutils hasn't implemented
all the quirks/features that we need for producing the hack non-PIC shared
objects. As it turned out, .o format isn't all that inconvenient after
all. It looks like the ability to use the same .o files for linking
directly into a static kernel or loading as a module might be worth it.
It is still very much a work-in-progress, but it is almost usable. Other
changes are still needed in order to use it though, these have not been
committed yet. There is still a memory corruption/overrun bug somewhere.
For example, test modules load and work, but the machine explodes a few
minutes later in vm_forkproc() or the like. Notable missing things
include kldxref support, and loader(8) support. I wanted to figure out
a working baseline set of code first.
we only pay attention to it during release time and at the moment it's
a -stable release in progress.
This is a MFS I guess, moving rev 1.536.2.113 to HEAD. I ran out of
time to follow through with doing this last night. Sorry for the delay.
Adding a couple of variables to make tweaking the CD-ROM label and .iso
filenames easier.
things which compare /etc/fstab entries to results from
getfsstat(). The real way to fix this is to make 'ufs2'
a recognized filesystem (for real, no beating around the
bush).
This should fix things like 'umount -a -t ufs' now.
Appologies for the previous breakage.
-U flag to bsdtar. Essentially, this option breaks existing hard
links. According to SUSv2, tar is supposed to overwrite existing
files on extract by default which, in particular, preserves
existing hard links. Note that this is yet another bug in gtar; it
appears to always break existing links. (Maybe gtar's -U is broken?)
I'm unsure about how to handle this for other file types; the current
code always unlinks first unless the NO_OVERWRITE flag is specified.
I've commented this issue liberally and will come back to it later.
boot0sio.s was repo-copied to boot0.S.
- Rename boot0ext.s to boot0ext.S, to stay consistent
with other preprocessed asm files around here, and
for better portability.

switch to using C99-style comments everywhere in preprocessed
assembler. The reason is that lines starting with the regexp
'^[[:space:]]#' are treated as preprocessing directives, and
while it seems to work now with GCC, it's not necessarily has
to work. Use C99 comments `//' for the trailing comments to
save whitespace.
