Revert r330897:

This was intended to be a non-functional change. It wasn't. The commit
message was thus wrong. In addition it broke arm, and merged crypto
related code.

Revert with prejudice.

This revert skips files touched in r316370 since that commit was since
MFCed. This revert also skips files that require $FreeBSD$ property
changes.

Thank you to those who helped me get out of this mess including but not
limited to gonzo, kevans, rgrimes.

Partial merge of the SPDX changes

These changes are incomplete but are making it difficult
to determine what other changes can/should be merged.

No objections from: pfg

Copy head@r302406 to stable/11 as part of the 11.0-RELEASE cycle.
Prune svn:mergeinfo from the new branch, as nothing has been merged
here.

Additional commits post-branch will follow.

Start each of the license/copyright comments with /*-, minor shuffle of lines

Do the dreaded s/dev_t/struct cdev */
Bump __FreeBSD_version accordingly.

Device megapatch 1/6:

Free approx 86 major numbers with a mostly automatically generated patch.

A number of strategic drivers have been left behind by caution, and a few
because they still (ab)use their major number.

Disabuse this driver of the notion that it needs to include
<sys/bus_private.h> to find the unit from a device_t.

Change Voodoo Graphics device ID to 0x0001121a so it gets probed.

Removed detection for Voodoo Banshee and Voodoo3 cards. I forsee certain
possible complications with the forthcoming DRI code, and feel that DRI
should handle the device-level interaction. Read
http://people.FreeBSD.org/~cokane/3dfx.html
to find out more. Basically want to move toward using OpenGL and DRI for
everything on these cards. Added a few defines and spacing style fixes in
tdfx_vars.h

Studied the tech docs for the Voodoo3 and Banshee, and hopefully fixed the
errors that plagued those cards with XFree86 4.0. They have two memory
ranges as well as an IO port range to them. Also cleaned up the three
warning messages that I got, from inb(), outb() and linuxulator. Also, I
noticed that the DRI and Glide support for the Voodoo4 and 5 has been
placed upon linux.3dfx.com, too bad they haven't released the tech docs
yet. Apparently, they are still pushing glide for all of us, so I will try
and add support once those tech docs are up.

Finish up the fixing of the linux ioctl stuff. Add line to remove the dev
entry upon unload.

Stick in header, $FreeBSD$.

This commit was generated by cvs2svn to compensate for changes in r61911,
which included commits to RCS files with non-trunk default branches.

First import of my 3dfx voodoo driver. Currently it supports the Voodoo Graphics and Voodoo2 perfectly. It works just like the 3dfx driver does for linux, by using a character device at /dev/3dfx of Major 107 to provide a window into the 3dfx card's memory space. This interface is used by glide and mesa as far as i know, and probably some other libraries too.
