"refreshing" the label on the vnode before use, just get the label
right from inception. For single-label file systems, set the label
in the generic VFS getnewvnode() code; for multi-label file systems,
leave the labeling up to the file system. With UFS1/2, this means
reading the extended attribute during vfs_vget() as the inode is
pulled off disk, rather than hitting the extended attributes
frequently during operations later, improving performance. This
also corrects sematics for shared vnode locks, which were not
previously present in the system. This chances the cache
coherrency properties WRT out-of-band access to label data, but in
an acceptable form. With UFS1, there is a small race condition
during automatic extended attribute start -- this is not present
with UFS2, and occurs because EAs aren't available at vnode
inception. We'll introduce a work around for this shortly.

Also, greatly expand the the upgrading from -stable part of this file.
It appears that you need new boot blocks to ensure that the right
kernel is booted single user.

anything better that fit the traditional 8.3 naming convention for
release documentation files.
an entry in /etc/sysctl.conf didn't exist. Fixing this exposed a minor
typo "exits" vs. "exist".
However, there doesn't appear to be any provision to run this with
the "lastload" argument, meaning that the error will never appear.
substitute normal DocBook. Pure coincidence that this thing built.
While here, pull in some more entities so that we can build in the

This is not quite the set of information I would want, but the tree where
I have the "correct" version is messed up with conflicts.

- Teach GCC about %y.

install works. Otherwise, a 'make installworld' without having already
rebooted with a post-signal-fix kernel is a rather big disaster when
important things like /bin/sh coredump.
handling clean and functional as 5.x evolves. This allows some of the
nasty bandaids in the 5.x codepaths to be unwound.
Encapsulate 4.x signal handling under COMPAT_FREEBSD4 (there is an
anti-foot-shooting measure in place, 5.x folks need this for a while) and
finish encapsulating the older stuff under COMPAT_43. Since the ancient
stuff is required on alpha (longjmp(3) passes a 'struct osigcontext *'
to the current sigreturn(2), instead of the 'ucontext_t *' that sigreturn
is supposed to take), add a compile time check to prevent foot shooting
there too. Add uniform COMPAT_43 stubs for ia64/sparc64/powerpc.
Tested on: i386, alpha, ia64. Compiled on sparc64 (a few days ago).
