John Baldwin	52b3919d31	Make these compile again by adding proc.h include for GIANT_REQUIRED ... that is in included vm headers.	2001-07-05 21:28:47 +00:00
Alfred Perlstein	2395531439	Introduce a global lock for the vm subsystem (vm_mtx). ... vm_mtx does not recurse and is required for most low level vm operations. faults can not be taken without holding Giant. Memory subsystems can now call the base page allocators safely. Almost all atomic ops were removed as they are covered under the vm mutex. Alpha and ia64 now need to catch up to i386's trap handlers. FFS and NFS have been tested, other filesystems will need minor changes (grabbing the vm lock when twiddling page properties). Reviewed (partially) by: jake, jhb	2001-05-19 01:28:09 +00:00
Doug Rabson	597472167a	A driver for programming the AGP hardware. This is only very lightly ... tested on Intel BX chipsets only. The other agp minidrivers are totally untested. The programming api is a subset of the Linux api and is only intended to be enough for the X server to use. There is also an in-kernel api for the use of other kernel modules such as the 3D DRI.	2000-06-09 16:04:30 +00:00
