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.
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.

* Consistently misspell built-in as builtin.
* 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.
* Undo English contractions.

reasonable defaults.
This avoids confusing and ugly casting to eopnotsupp or making dummy functions.
Bogus casting of filesystem sysctls to eopnotsupp() have been removed.
This should make *_vfsops.c more readable and reduce bloat.

return (in signal trampoline code). I plan to do the same on -stable,
so that we have a consistent interface to userland applications.
