s/with historical makefils//. Also, relocate and change the description
of VPATH to be a little sexier. I'd say it looks a bit like Claudia
Schiffer now, which I consider a definate improvement. We're also a little
more subtle about saying that VPATH is for backward(s) compatibility.
Submitted-by: chris, bde, and myself
[although none of their descriptions were as sexy
M(|is|r)s Schiffer, of course].
Remove the #include of sys/param.h. It was meant to improve portability
for BSD less than 4.4 where sys/cdefs.h DNE but can be simulated with
param.h. Unfortunately, the additional include did little to actually
improve portability since we've lost portability in several other chunks
of make code (err(), sysctlbyname(), probable more).

Document VFS changes:
VFS_CHECKEXP.9, now used to check export credentials
VFS_FHTOVP.9, only used for filehandle to vnode, no access checks are done.
VFS.9, inform people of the vfs_std* functions available to avoid
ugly casts to eopnotsup and making of dummy functions to return 0.

Make a bit more headway with dd's argument parsing, etc. get_bsz() is
renamed get_num() since it's not just about block sizes. skip and
seek can be any offset, including negative, now. Some style bogons are fixed.

Add the CR4 values for P3 SIMD enabling support. FXSR tells the cpu that
the OS does FXSAVE/FXRESTOR instructions (fast FPU save/restore) during
context switching and also enables SIMD since this enables saving the
extra CPU context that isn't saved with normal FPU regs. The other
enables the SIMD instructions to use exception 16 (FPU) error reporting.
Note, this doesn't turn on SIMD, just defines the bits.

Add text for the PN (Processor serial number) and XMM (extended SIMD/MMX2/
support), as well as a bunch of comments for what the various bits mean
(those that I remember anyway).
In the words of originator:
:If an incoming connection is initiated through natd and deny_incoming is
:not set, then a new alias_link structure is created to handle the link.
:If there is nothing listening for the incoming connection, then the kernel
:responds with a RST for the connection. However, this is not processed
:correctly in libalias/alias.c:TcpMonitor{In,Out} and
:libalias/alias_db.c:SetState{In,Out} as it thinks a connection
:has been established and therefore applies a timeout of 86400 seconds
:to the link.
:
:If many of these half-connections are initiated (during, for example, a
:port scan of the host), then many thousands of unnecessary links are
:created and the resident size of natd balloons to 20MB or more.
* Add a builtin(1) manpage and create builtin(1) MLINKS for all shell
builtin commands for which no standalone utility exists. These MLINKS
replace those that were created for csh(1).
* Add appropriate xrefs for builtin(1) to the csh(1) and sh(1) manpages,
as well as to the manpages of standalone utilities which are supported
as shell builtin commands in at least one of the shells. In such
manpages, explain that similar functionality may be provided as a
shell builtin command.
* Improve sh(1)'s description of the cd builtin command. Csh(1) already
describes it adequately. Replace the cd(1) manpage with a builtin(1)
MLINKS link.
* Clean up some mdoc problems: use Xr instead of literal "foo(n)"; use
Ic instead of Xr for shell builtin commands.

Add a pointer to "controller miibus0" for people who will not read the
commit messages or GENERIC and insist on running -CURRENT.
It probably won't work, but it's worth a try.
Save %gs in sigcontext when delivering a signal and restore them upon
return (in signal trampoline code). I plan to do the same on -stable,
so that we have a consistent interface to userland applications.
