Not really. The first part of the patch looks like this:

> diff --git a/drivers/gpu/drm/radeon/r600.c b/drivers/gpu/drm/radeon/r600.c
> index 667c237..5668b90 100644

That function looks like this here though:

> void r600_ioctl_wait_idle(struct radeon_device *rdev, struct radeon_bo *bo)
> {
> 	WREG32(R_005480_HDP_MEM_COHERENCY_FLUSH_CNTL, 0x1);
> }

Thus this hunk already fails to apply.
