Merge branch 'drm-fixes-4.2' of git://people.freedesktop.org/~agd5f/linux into drm-fixes
radeon and amdgpu fixes for 4.2. All over the place:
- fix cursor corruption on resume and re-enable no VT switch on suspend
- vblank fixes
- fix gpuvm error messages
- misc other fixes
* 'drm-fixes-4.2' of git://people.freedesktop.org/~agd5f/linux:
drm/radeon: disable vce init on cayman (v2)
drm/amdgpu: fix timeout calculation
drm/radeon: check if BO_VA is set before adding it to the invalidation list
drm/radeon: allways add the VM clear duplicate
Revert "Revert "drm/radeon: dont switch vt on suspend""
drm/radeon: Fold radeon_set_cursor() into radeon_show_cursor()
drm/radeon: unpin cursor BOs on suspend and pin them again on resume (v2)
drm/radeon: Clean up reference counting and pinning of the cursor BOs
drm/radeon: fix underflow in r600_cp_dispatch_texture()
drm/radeon: default to 2048 MB GART size on SI+
drm/radeon: fix HDP flushing
drm/radeon: use RCU query for GEM_BUSY syscall
drm/amdgpu: Handle irqs only based on irq ring, not irq status regs.
drm/radeon: Handle irqs only based on irq ring, not irq status regs.

Q: Can I suspend-to-disk using a swap partition under LVM?
-A: No. You can suspend successfully, but you'll not be able to
-resume. uswsusp should be able to work with LVM. See suspend.sf.net.
+A: Yes and No. You can suspend successfully, but the kernel will not be able
+to resume on its own. You need an initramfs that can recognize the resume
+situation, activate the logical volume containing the swap volume (but not
+touch any filesystems!), and eventually call
+
+echo -n "$major:$minor" > /sys/power/resume
+
+where $major and $minor are the respective major and minor device numbers of
+the swap volume.
+
+uswsusp works with LVM, too. See http://suspend.sourceforge.net/
Q: I upgraded the kernel from 2.6.15 to 2.6.16. Both kernels were
compiled with the similar configuration files. Anyway I found that
