9c03c0d88c Rework how drm maps are handled.
* On 32 bit platforms we steal the upper 4 bits of the map handle
   to store a unique map id.
 * On 64 bit platforms we steal the upper 24 bits.

Resolves issues where the offsets that are handed to mmap may overlap the VRAM on some cards.

Tested on: radeon, intel, mga, and via.

This will break nouveau.  I will spin new patches shortly.

096924c9b7 Remove explicit setting of NO_CTF in WMAKEENV and in the make call for
the buildkernel. This way makeoptions WITH_CTF=yes not only works when
compiling the tradtitional way, but also when using buildkernel. This
does not enable the CTF part of the world, it still defaults to without
CTF info.

The cross/build-tools/bootstrap targets are not affected by this, they
still have and should keep the explicit NO_CTF.

7ab4cc53fd Revert r206179 (by imp) and do something similar which is more consistent
with all other corresponding CTF places by changing the corresponding
code which is generated by config(8). Or in short, move the '@' from
the variable definition to the use of the variable. [1]

While I'm here break up a long line. [2]

dc00aa5dd6 ln: Allow a trailing slash when creating a link to a directory.
In the 'ln source... directory' synopsis, the basename of each source
determines the name of the created link. Determine this using basename(3)
instead of strrchr(..., '/') which is incorrect if the pathname ends in a
slash.

The patch is somewhat changed to allow for basename(3) implementations that
change the passed pathname, and to fix the -w option's checking also.
The code to compare directory entries only applies to hard links, which
cannot be created to directories using ln.

Example:
  ln -s /etc/defaults/ /tmp
This should create a symlink named defaults.

3acd904d85 Change usb devd events from fake attach to a notify. The ugen device is not a
proper device_t so it faked the devctl event to appear like one, this is now a
notify which allows more information to be passed.

We notify for both the device attach/detach and for each usb interface. A devd
rule can now match on the interface properties, including composite devices
which may have a uvideo interface and also usound and possibly uhid too.

An example to match a umass device with a scsi subclass and BBB protocol would be

notify 100 {
	match "system"          "USB";
	match "subsystem"       "INTERFACE";
	match "type"            "ATTACH";
	match "intclass"        "0x08";
	match "intsubclass"     "0x06";
	match "intprotocol"     "0x50";
	action ...
};

The old attach devctl event has been retained for the moment to make merging to
8.1 easier. This was never compatible with 7.x or earlier due to the ugen regex
change needed.

bd34cda61a Bump minor version of config to reflect the new option remapping
feature.  The kernel makefiles have specifically not been bumped
because nothing uses this new feature and doing so forces everybody to
recompile for no good reason.  This chnage will be MFC'd where the
kernel version numbers for amd64 and ia64 will be bumped, since those
are the only two that have use the option remapping feature.  Once
merged, this will give a better error message to folks that are using
buildkernel without buildworld or kernel-toolchain to update their
kernels.

5673e3cb08 The cache_enter(9) function shall not be called for doomed dvp.
Assert this.

In the reported panic, vdestroy() fired the assertion "vp has namecache
for ..", because pseudofs may end up doing cache_enter() with reclaimed
dvp, after dotdot lookup temporary unlocked dvp.
Similar problem exists in ufs_lookup() for "." lookup, when vnode
lock needs to be upgraded.

Verify that dvp is not reclaimed before calling cache_enter().
