b6d9e06815 * Fix a couple of places in the device pager where an address was
truncated to 32 bits.
* Change the calling convention of the device mmap entry point to
  pass a vm_offset_t instead of an int for the offset allowing
  devices with a larger memory map than (1<<32) to be supported
  on the alpha (/dev/mem is one such).

These changes are required to allow the X server to mmap the various
I/O regions used for device port and memory access on the alpha.

337322b7ec Moved `nx' functions to the one place where they are used (su.c).
They shouldn't be used there either.  They should have gone away
about 3 years ago when the statically initialized devswitches went
away, but su.c unfortunately still frobs the cdevswitch in the old
way.

1d5f38ac22 This commit fixes various 64bit portability problems required for
FreeBSD/alpha.  The most significant item is to change the command
argument to ioctl functions from int to u_long.  This change brings us
inline with various other BSD versions.  Driver writers may like to
use (__FreeBSD_version == 300003) to detect this change.

The prototype FreeBSD/alpha machdep will follow in a couple of days
time.

94b6d72794 Back out part 1 of the MCFH that changed $Id$ to $FreeBSD$. We are not
ready for it yet.

10f666af84 This is the kernel Lite/2 commit. There are some requisite userland
changes, so don't expect to be able to run the kernel as-is (very well)
without the appropriate Lite/2 userland changes.

The system boots and can mount UFS filesystems.

Untested: ext2fs, msdosfs, NFS
Known problems: Incorrect Berkeley ID strings in some files.
		Mount_std mounts will not work until the getfsent
		library routine is changed.

808a36ef65 Make the long-awaited change from $Id$ to $FreeBSD$
This will make a number of things easier in the future, as well as (finally!)
avoiding the Id-smashing problem which has plagued developers for so long.

Boy, I'm glad we're not using sup anymore.  This update would have been
insane otherwise.

08b652fb65 Replaced bogus macros for dummy devswitch entries by functions.
These functions went away:

	enosys (hasn't been used for some time)
	enxio
	enodev
	enoioctl (was used only once, actually for a vop)

if_tun.c:
Continued cleaning up...

conf.h:
Probably fixed the type of d_reset_t.  It is hard to tell the correct
type because there are no non-dummy device reset functions.

Removed last vestige of ambiguous sleep message strings.

fb586a0db4 Make pcvt and syscons live in the same kernel. If both are enabled, then
the first one in the config has priority.  They can be switched using
userconfig().

i386/i386/conf.c:
Initialize the shared syscons/pcvt cdevsw entry to `nx'.

Add cdevsw registration functions.

Use devsw functions of the correct type if they exist.

i386/i386/cons.c:
Add renamed syscons entry points to constab.

i386/i386/cons.h:
Declare the renamed syscons entry points.

i386/i386/machdep.c:
Repeat console initialization after userconfig() in case the current
console has become wrong.  This depends on cn functions not wiring down
anything important.

sys/conf.h:
Declare new functions.

i386/isa/isa.[ch]:
Add a function to decide which display driver has priority.  Should be
done better.

i386/isa/syscons.c:
Rename pccn* -> sccn*.

Initialize CRTC start address in case the previous driver has moved it.

i386/isa/syscons.c, i386/isa/pcvt/*
Initialize the bogusly shared variable Crtat dynamically in case the
stored value was changed by the previous driver.

Initialize cdevsw table from a template.

Don't grab the console if another display driver has priority.

i386/isa/syscons.h, i386/isa/pcvt/pcvt_hdr.h:
Don't externally declare now-static cdevsw functions.

i386/isa/pcvt/pcvt_hdr.h:
Set the sensitive hardware flag so that pcvt doesn't always have lower
priority than syscons.  This also fixes the "stupid" detection of the
display after filling the display with text.

i386/isa/pcvt/pcvt_out.c:
Don't be confused the off-screen cursor offset 0xffff set by syscons.

kern/subr_xxx.c:
Add enough nxio/nodev/null devsw functions of the correct type for syscons
and pcvt.
