Mostly whitespace cleanups and style(9) fixes focused on "if(" -> "if ("
...
Change some nearby memset()s to bzero()s or to calloc allocations to
take advantage of M_ZERO). Reverse some error tests to reduce high
levels of indentation. Move the sg_cleanup() call out of the maplist
loop in DRM(takedown)-- I can't see any need for it to be inside.

Port the SiS DRM to FreeBSD. This includes the ability for the DRM to
...
allocate framebuffer memory without sisfb, and a new ioctl to be used
by the X Server which tells the DRM what region of framebuffer memory
to allocate from. Also fixes a possibility to panic the kernel I
believe. Tested on linux with sisfb and FreeBSD (without sisfb) with
new DRI only.

Add DRMFILE definitions and supply filp for BSD in the
...
post-drm-filp-0-1-branch world. The filp is a void * cast from the
current pid. This is a temporary solution which maintains the status
quo until a proper solution is implemented.
What is really needed is a unique pointer per open, hopefully with a device
private area. This can be done in FreeBSD for all entry points except
mmap, but is difficult (sys/dev/streams/streams.c is an example). I
have partially completed code for this but have not had time to debug,
so this is a temporary fix.
