*	use a single preinitialised mutex for atomic64 fallback path	jsg	2020-11-09	1	-14/+16
\| \| \| \| \| \| \| \| \| \| \|	Previously we would initialise a variable specific mutex in ATOMIC64_INIT() or atomic64_set() but the drm code in multiple places zeroes memory and later accesses it without calling these resulting in a mutex with IPL_NONE instead of IPL_HIGH. Fixes a 'locking against myself' panic reported by Anthony Richardby on macppc with PowerBook5,6 and RV350. ok kettenis@

*	Update shared drm code, inteldrm(4) and radeondrm(4) from linux 4.4 to	jsg	2019-04-14	1	-0/+425
	linux 4.19.34. Adds support for more Intel hardware: Broxton/Apollo Lake (was is_preliminary in 4.4) Amber Lake (another Kaby Lake refresh) Gemini Lake Coffee Lake Whiskey Lake Cannon Lake (though no hardware with Intel graphics ever shipped) Ice Lake (alpha support, hardware not released) This does not add support for new radeon hardware on the AMD side as newer radeons have a different kernel driver (amdgpu). Thanks to the OpenBSD Foundation for sponsoring this work, kettenis@ for helping and a bunch of other developers for testing.
