lockmgr exorcism
take 42. http://marc.info/?l=openbsd-tech&m=130999022613838&w=2
Updated diff follows below. Add rrwlocks. Make lockmgr a wrapper shim.
Tests, oks, the whole nine yards, please. And maybe if I get lucky this
can get committed before it's two years old...

This is a stupid simple diff to see just how much time you spend
waiting for your disk. If you're into measuring that kind of thing.

libc warnings
To prevent the future recurrence of some rather serious libc build
bugs, such as a macro like strong_alias suddenly turning into an
implicit function prototype, I think we should add some warnings and
use as much -Werror as possible. (I'm not entirely sure this would
have caught the missing strong_alias macro, but it seems like a good
idea anyway.)
This adds a (very) few warnings and fixes some of the fallout. The
diff is a bit of a mix of things, since I initially tried -Wall before
I ran away screaming. Over time, maybe some brave pioneers can expand
the frontier.

Stolen memory
Machines with Intel integrated graphics have this concept of stolen
memory; system memory set aside by the BIOS for use by the graphics
chip. On OpenBSD we don't touch that memory since we don't want to
step on the BIOS' toes. We also assume that this memory is mapped in
the graphics translation table (GTT). So we reserve a block of the
size of the stolen memory at the start of the aperture and never use
it.
On modern machines this strategy doesn't make a lot of sense. The
size of the stolen memory can be larger than the graphics aperture,
leaving inteldrm(4) no space to map framebuffers and other graphics
objects.
The diff below gets rid of this policy on Sandy Bridge and Ivy Bridge
CPUs, making the full aperture available for use by inteldrm(4). This
works fine on my x220, but before I commit this, I'd like to see a
little bit more testing. If you have a machine with Intel HD Graphics
2000/3000/2500/4000, please give this diff a try. If possible, test
the following:
* Check that X still works properly.
* Check that suspend/resume still works. (Don't bother if
suspend/resume doesn't work without this diff).
* Disable the inteldrm driver (boot with the -c option, disable
inteldrm at the UKC> prompt) and check if the VGA text console
still works properly.
Thanks,
Mark
