The "USL" VT switch and keyboard ioctls are a hack and don't follow the
proper BSD way where the third argument is always a pointer and data is

The "USL" VT switch and keyboard ioctls are a hack and don't follow the
proper BSD way where the third argument is always a pointer and data is
transferred between userland and kernel using copyin(9) and copyout(9).
Intead an int is encoded in the thirs argument. This works on 32-bit
architectures and little-endian 64-bit architectures. But not on
big-endian 64-bit architectures. Deal with this by handling the argument
as long (which matches the size of a pointer).

Hopefully we can eliminate these ioctls in the near future.

Only allow change-setting ioctls when FWRITE is set on the descriptor.
ok I forget who

Remove 'option COMPAT_PCVT' now that X doen't use it anymore.
An X server built after april 3 is needed to be able to start X with
the new kernel.

OpenBSD has stopped using the SVr4 KDENABIO/KDDISABIO ioctls for at
least 10 years. No need for special treatement on i386.

ok deraadt@, millert@, jca@

Remove WSDISPLAY_COMPAT_SYSCONS. We no longer run FreeBSD binary X11
servers. Pointed out by jmc@, ok deraadt@ millert@

sizes for free(); checked by semarie

Remove some includes include-what-you-use claims don't
have any direct symbols used. Tested for indirect use by compiling
amd64/i386/sparc64 kernels.

ok tedu@ deraadt@

add a size argument to free. will be used soon, but for now default to 0.
after discussions with beck deraadt kettenis.

For the WSDISPLAY_COMPAT_USL protocol, send the synchronizing signals to
the process, not just the thread.

ok kettenis@

guenther notes that s_pid must also move to match

Yet another ioctl-related pid value. Should be the master of the
thread, aka. p_p->ps_pid.
ok miod

Push COMPAT_FREEBSD in front of a whale. Buggy, out of date, no
one has been weeding it, and it makes life harder.

Toasts of Brennivin for its passing from many; diff ok henning@

ansify function definitions, and constify a few arrays while there.
no functional change.

Convert timeout_add() calls using multiples of hz to timeout_add_sec()

Really just the low-hanging fruit of (hopefully) forthcoming timeout
conversions.

FALLTHRU -> FALLTHROUGH for consistency.
Suggested by miod@

Fix some more "is is"s. ok otto@.

Do not fail KDENABIO and KDDISABIO ioctls on non-i386 platforms, this allows
older X servers to run; ok matthieu@

Make routines which may set PSL_IOPL consistent wrt the securelevel for
which this is allowed; ok deraadt@

remove terms 3 & 4 for drochner@NetBSD.org; as seen on netbsd lists

change arguments to suser. suser now takes the process, and a flags
argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root proces

change arguments to suser. suser now takes the process, and a flags
argument. old cred only calls user suser_ucred. this will allow future
work to more flexibly implement the idea of a root process. looks like
something i saw in freebsd, but a little different.
use of suser_ucred vs suser in file system code should be looked at again,
for the moment semantics remain unchanged.

Add signal number sanity checking to usl_sync_init(). This is not
strictly required since the signal routines do their own sanity checks,
but this way the VT_SETMODE ioctl() gets a nice EINVAL.
