from old signal handlers. This is simpler and faster, and fixes (new)
sigreturn(2) when %eip in the new signal context happens to match the
magic value (0x1d516). 0x1d516 is below the default ELF text section,
so this probably never broken anything in practice.
locore.s:
In addition, don't build the signal trampoline for old signal handlers
when it is not used.
alpha:
Not fixed, but seems to be even less broken in practice due to more
advanced magic. A false match occurs for register #32 in mc_regs[].
Since there is no hardware register #32, a false match is only possible
for direct calls to sigreturn(2) that happen to have the magic number
in the spare mc_regs[32] field.
DOCDISTFILES if defined. No impact should happen with this change.
DOCDISTFILES is introduced by rev. 1.541, to point the directory that
contains the distfiles for ports/textproc/docproj. It's good, but
we also build ports/sysutils/mkisofs during the release (if MAKE_ISOS
is defined). It is natural that cdrtools tarball is prefetched, then
copy it under ${CHROOTDIR}/usr/ports/distfiles.
As a result, DOCDISTFILES variable is somewhat abused for non-doc
tarballs; *DOC*DISTFILES is no longger appropriate name for that.

call VOP_INACTIVE before placing the vnode back on the free list.
Otherwise there is a race condition on SMP machines between
getnewvnode() locking the vnode to reclaim it and vrele()
locking the vnode to inactivate it. This window of vulnerability
becomes exaggerated in the presence of filesystems that have
been suspended as the inactive routine may need to temporarily
release the lock on the vnode to avoid deadlock with the syncer
process.

dup2(2) incorrectly assumes that if it needs to grow the ofiles
array that it will get what it wants. This assertion was valid
before we allowed shared filedescriptor tables but is now incorrect.
The assertion can trigger superfolous panics if the thread doing a
dup2 looses a race with another thread while possibly blocked in
the MALLOC call in fdalloc. Another thread may grab the slot we
are requesting which makes fdalloc return something other than what
we asked for, this will triggering the bogus assertion.

Note that the "NO_PROFILE_DATA"/"NO_PROFILE_COUNTERS" bits were added
to the stock FSF GCC 2.97 (and thus 3.1) source as i386 Linux needed them
also. (amazing what can get committed to the FSF GCC when needed by Linux...)
