the previous frame is in the usual place even for traps, interrupts
and syscalls in the kernel, because the assembly language stubs
don't change the frame pointer. The previous frame is just not for
the calling function. We may as well depend on this as on magic to
determine the trap frame address. The magic is in FRAME_SAVED_PC()
which elides the correct number of stubs (1) to go back to a pc that
matches the previous frame.
Removing fbsd_kern_frame_chain() fixes bugs in it. Xsyscall was
misspelled as _Xsyscall (gdb removes one leading underscore), so
the tf_syscall frame type was never found. This was harmless
because tf_normal works in all cases in fbsd_kern_frame_chain()
and Xsyscall is spelled correctly in fbsd_kern_frame_saved_pc()
where it matters. There were style bugs on almost every line,
starting with a primary indent of 7.
and the pre-Lite2 vfsconf interfaces.
For quot, just back out revs. 1.1 and 1.2 and change MNT_FFS to
"ufs", so that vfsconf isn't used at all. Revs. 1.1 and 1.2 were
hacks to get around f_fstypename not being in `struct statfs' in
Lite1.
and the pre-Lite2 vfsconf interfaces.
For getvfsent.c, just define _OLD_VFSCONF. This will give the
current default macro hacks in <sys/mount.h> when the default is
reversed. This is an intermediate step.
and the pre-Lite2 vfsconf interfaces.
For lsvfs, use the new interface for getvfsbyname(), and use the
old interface for getvfsent() explicitly instead of depending on
macro hacks in <sys/mount.h>. This is an intermediate step.
makefile doesn't install them, and they couldn't be used without
lots of undocumented -I's in CFLAGS. tcl.h is still installed in
/usr/include/tcl/. Note that rev.1.24 of tcl_bmake/mkMakefile.sh
broke all the section 3 tcl man pages by putting it there instead
of in /usr/include.
When building a release, RELEASE_CRUNCH is defined for a `make' of
the objects required by the crunch of each program. The object list
is still obtained in the same way, so you must make sure that all
objects are built (empty if necessary) by this make. ppp/Makefile
provides an example.

config option in pmap. Fix a problem with faulting in pages. Clean-up
some loose ends in swap pager memory management.
The system should be much more stable, but all subtile bugs aren't fixed yet.
This is Junichi's v1.0 driver.
NOTE: Major device numbers have been changed to avoid conflict with other
FreeBSD 3.0 devices. The new numbers should be considered "official."
This driver is still considered "beta" quality, although we have been
playing with it. Please submit bugs to junichi and myself.

not quite correct, because the Makefiles in lkm/syscons don't set up the
`machine' symlink, but other, more volatile headers in <machine> are
already used.
are in kvm_uread():
- the setting of errno before checking it in the lseek() was lost.
- EOF handling was lost. kvm_uread() retried forever on EOF. EOF is
not really an error, but report it one as in rev.1.2.
- reporting of errno after a read error was lost.
Fixed style bugs in rev.1.3 and rev.1.12.
Not fixed: errno is not reported after lseek() failures.
isn't gratuitously broken. This also prevents ANSI compilers from
recognizing the pragma as a request to run /usr/games/hack...
FreeBSD Ids should be in comments or rcsids, not in `#pragma ident's
(which are equivalent to comments when compiled by gcc), and the
only FreeBSD change in this file seems to be adding the Id.
