Reorganize /etc/rc.d/syscons and move all keyboard related settings
into one function syscons_configure_keyboard(). Call new function from
both syscons_start() and sysconst_setkeyboard(). The reason for this
is because syscons_start() will (re)configure both keyboard and screen
settings. Apparently, some graphics cards have problems with running
vidcontrol(1) while X11 is running.
Remove "/etc/rc.d/syscons restart" from /etc/devd.conf. It is no longer
required. Using "/etc/rc.d/syscons setkeyboard" is enough. This also
should fix annoying "syscons not running?" message.

When opening a trace file, open O_NONBLOCK so that ktrace doesn't stall
if the target is a fifo. After opening a trace file, check that it is a
regular file, and if not, return an error.

If fifo_open() is called with a negative file descriptor, return EINVAL
rather than panicking later. This can occur if the kernel calls
vn_open() on a fifo, as there will be no associated file descriptor,
and therefore the file descriptor operations cannot be modified to
point to the fifo operation set.

Only catch SIGINFO (for dumping thread states) when LIBPTHREAD_DEBUG
is defined in the environment.
Modify the code path of the ifdef NOTYET part of _kse_single_thread():
o Don't reinitialise the atfork() handler list in the child. We
are meant to call the child handler, and on subsequent fork()s
should call all three functions as normal.
o Don't reinitialise the thread specific keyed data in the
child after a fork. Applications may require this for context.
o Reinitialise curthread->tlflags after removing ourselves from
(and reinitialising) the various internal thread lists.
o Reinitialise __malloc_lock in the child after fork() (to balance
our explicitly taking the lock prior to the fork()).
With these changes, it is possible to enable the NOTYET code in
thr_kern.c to allow the use of non-async-safe functions after
fork()ing from a threaded program.
Eliminate a race condition in timed waits (cv, mutex, and sleeps).
Don't forget to initialize a tailq before using it.
For the ``#ifdef NOTYET'' code that allows calling non-async-safe
functions in the child after a fork() from a threaded process,
use __sys_setprocmask() rather than setprocmask() to keep our
signal handling sane. Without this fix, signals are essentially
ignored in said child and things such as protection violations
result in an endless busy loop.
Allocate a thread's tcb last so it is easier to handle failures to
malloc() siginfo.
Include needed headers that were obtained through <pthread.h>. Sort headers
while here.

Use sf_buf_alloc() instead of vm_map_find() on exec_map to create
the ephemeral mappings that are used as the source for three copy
operations from kernel space to user space. There are two reasons
for making this change: (1) Under heavy load exec_map can fill up
causing vm_map_find() to fail. When it fails, the nascent process
is aborted (SIGABRT). Whereas, this reimplementation using
sf_buf_alloc() sleeps. (2) Although it is possible to sleep on
vm_map_find()'s failure until address space becomes available (see
kmem_alloc_wait()), using sf_buf_alloc() is faster. Furthermore,
the reimplementation uses a CPU private mapping, avoiding a TLB
shootdown on multiprocessors.
The second argument to vm_map_find() should be NULL instead of 0.
Correct a long-standing problem in elfN_map_insert(): In order to
copy a page to user space, the user space mapping must allow write
access.
Eliminate an unneeded (vm_prot_t) parameter from two functions.
Eliminate unnecessary uses of a local variable.
Maintain the vnode lock throughout elfN_load_file() rather than
releasing it and reacquiring it in vrele(). Consequently, there is
no reason to increase the reference count on the vm object caching
the file's pages.
Eliminate unused parameters to elfN_load_file().
Maintain the lock on the vnode for most of exec_elfN_imgact().
Specifically, it is required for the I/O that may be performed by
elfN_load_section().
Avoid an obscure deadlock in the a.out, elf, and gzip image
activators. Add a comment describing why the deadlock does not
occur in the common case and how it might occur in less usual
circumstances.
Eliminate an unused variable from exec_aout_imgact().
Avoid a vm object reference leak in a rarely used code path.
An executable contains at most one PT_INTERP program header.
