were not mentioned; the callout_activate/deactivate/pending macros are
still not mentioned).

rev.1.168 should have been committed concurrently:
Fixed some style bugs (always use precisely 1 space after `:' in
dependency specifications).
Removed bogus dependency of ${FULLKERNEL} on ${BEFORE_DEPEND}.

Changed the type used to represent the user stack pointer from `long *'
to `register_t *'. This fixes bugs like misplacement of argc and argv
on the user stack on i386's with 64-bit longs. We still use longs to
represent "words" like argc and argv, and assume that they are on the
stack (and that there is stack). The suword() and fuword() families
should also use register_t.

register_t, so pointers to it must be passed around as `register_t *',
not as `int *'. The type mismatches were non-benign on alphas, but
the broken code is normally only configured by LINT.
Fix some ctype problems - isascii() caused a warning if fed an unsigned
char - it's always > 0 and libstand is compiled with -Wall.
Missing prototype/include in printf.c
and is module aware. Yes, this means that kvm_nlist(3) will find symbols
in loaded modules. The emulation of the nlist struct is pretty crude but
seems to work well enough for all the users in the tree that I found.
functions to be used by the dynamic linker. This can be called by
threads packages at start-up time. I will add the call to libc_r
soon.
Also add a default locking method that is used up until dllockinit()
is called. The default method works by blocking SIGVTALRM, SIGPROF,
and SIGALRM in critical sections. It is based on the observation
that most user-space threads packages implement thread preemption
with one of these signals (usually SIGVTALRM).
The dynamic linker has never been reentrant, but it became less
reentrant in revision 1.34 of "src/libexec/rtld-elf/rtld.c".
Starting with that revision, multiple threads each doing lazy
binding could interfere with each other. The usual symptom was
that a symbol was falsely reported as undefined at start-up time.
It was rare but not unseen. This commit fixes it.

is not configured. Including <isa/isavar.h> when it is not used is
harmful as well as bogus, since it includes "isa_if.h" which is not
generated when isa is not configured.
Fixed some style bugs for cam (superflous umask and missing newline).
Fixed bogons for apm. The pattern "apm*" matched too many things; apm
and apmctl were both made twice by `MAKEDEV all'. Hopefully no one
depends on `MAKEDEV apm0' making apm or on `MAKEDEV apm' making apmctl.
fixee incoherency of pipe timestamps relative to file timestamps in
the usual case where getnanotime() is not used for the latter. (File
and pipe timestamps are still incoherent relative to real time unless
the vfs_timestamp_precision sysctl is set to 2 or 3).
Some interface botches went away, leaving the macros unused outside of
the implementation of interrupt masking, and it was silly for the
implementation to use the macros in only one place each.
Use SYMLINKS instead of an ad hoc rule for installing words -> web2.
Don't override the install target; doing so just breaks things like
SYMLINKS.
Don't override the correct defaults for the all, clean, depend, lint
and tags targets. Don't add a null rule to the cleandepend target.
the docs on a couple other keys. While I'm here, document another ~3 bugs
that have been around for all eternity in the hope that I'll someday bother
to fix them.
