-Subject: [PATCH] drm/v3d: Don't clear MMU control bits on exception
-
-MMU exception conditions are reported in the V3D_MMU_CTRL register as
-write-1-to-clear (W1C) bits. The MMU interrupt handling code clears any
-exceptions, but does so by masking out any other bits and writing the
-result back. There are some important control bits in that register,
-including MMU_ENABLE, so a safer approach is to simply write back the
-value just read unaltered.
-
-This patch doesn't remove the cause of the apparent PTE errors, but it
-does reduce the impact to just an error in the kernel log.
