of being able to use Gzip'ed distributions.

loading breakage'). The patch fixes serious issues with the VFS
operations vector array which results in a crash when a filesystem module
adding a new VOP is loaded into the kernel. Basically what was happening
before was that the old operations vector was being freed and a new one
allocated. The original MALLOC code tended to reuse the same address
for the case and so the bug did not rear its ugly head until the new memory
subsystem was emplaced.
This patch replaces the temporary workaround Dave O'Brien comitted in 1.58.
The patch is clean enough that I intend to MFC it to stable at some point.

You need to set TARGET_ARCH and possibly TARGET, the same
way you normally do it for a cross build(7).
Renamed `distribworld' to a more natutal `distributeworld'.
Put pwd_mkdb(8) under ${INSTALLTMP}; for `distributeworld'.
0xdeadc0de and then check for it just before memory is handed off as part
of a new request. This will catch any post free/pre alloc modification of
memory, as well as introduce errors for anything that tries to dereference
it as a pointer.
This code takes the form of special init, fini, ctor and dtor routines that
are specificly used by malloc. It is in a seperate file because additional
debugging aids will want to live here as well.
only for exceptions.
While adding this to exception_save and exception_restore, it was hard
to find a good place to put the instructions. The code sequence was
sufficiently arbitrarily ordered that the density was low (roughly 67%).
No explicit bundling was used.
Thus, I rewrote the functions to optimize for density (close to 80% now),
and added explicit bundles and nop instructions. The immediate operand
on the nop instruction has been incremented with each instance, to make
debugging a bit easier when looking at recurring patterns. Redundant
stops have been removed as much as possible. Future optimizations can
focus more on performance. A well-placed lfetch can make all the
difference here!
Also, the FRAME_Fxx defines in frame.h were mostly bogus. FRAME_F10 to
FRAME_F15 were copied from FRAME_F9 and still had the same index. We
don't use them yet, so nothing was broken.
the block to read and copy out. This removes the hack in
udf_readatoffset() for only reading one block at a time. WooHoo!
Remove a redundant test for fragmented fids in both udf_readdir()
and udf_lookup(). Add comment to both as to why the test is
written the way it is. Add a few more safety checks for brelse().
Thanks to Timothy Shimmin <tes@boing.melbourne.sgi.com> for pointing
out these problems.
sent me a replacement patch that fixes the problem. The challenge
buffer was not large enough by a factor of 4 (due to my changing the
size from 128 to 32, but not u_int8_t to u_int32_t).
