2015-08-17drm/amdgpu: wait on page directory changes. v2Bas Nieuwenhuizen
Pagetables can be moved and therefore the page directory update can be necessary for the current cs even if none of the the bo's are moved. In that scenario there is no fence between the sdma0 and gfx ring, so we add one. v2 (chk): rebased Signed-off-by: Bas Nieuwenhuizen <bas@basnieuwenhuizen.nl> Signed-off-by: Christian König <christian.koenig@amd.com> Reviewed-by: Alex Deucher <alexander.deucher@amd.com>

2015-08-17drm/amdgpu: don't grab dev->struct_mutex in pm functionsDaniel Vetter
Similar to radeon, except that amdgpu doesn't even use struct_mutex to protect anything like the shared z buffer (sane gpu architecture, yay!). And the code already grabs the globa adev->ring_lock, so this code can't race with itself. Which makes struct_mutex completely redundnant. Remove it.

2015-08-17drm/amdgpu: Don't take dev->struct_mutex in bo_force_deleteDaniel Vetter
It really doesn't protect anything which doesn't have other locks already. Also this is run from driver unload code so not much need for locks anyway. Same changes as for radeon really.

2015-08-17drm/radeon: Don't take dev->struct_mutex in pm functionsDaniel Vetter
We already grab 2 device-global locks (write-sema rdev->pm.mclk_lock and rdev->ring_lock), adding another global mutex won't serialize this code more. And since there's really nothing interesting that gets protected in radeon by dev->struct mutex (we only have the global z buffer owners and it's still serializing gem bo destruction in the drm core - which is irrelevant since radeon uses ttm anyway internally) this doesn't add protection. Remove it.
