Origin: https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git/commit?id=1bd81429d53ded4e111616c755a64fad80849354 Bug-Debian: https://bugs.debian.org/990312 commit ee5468b9f1d3bf48082eed351dace14598e8ca39 upstream. This reverts commit 4cbbe34807938e6e494e535a68d5ff64edac3f20. Reason for revert: side effect of enlarging CP_MEC_DOORBELL_RANGE may cause some APUs fail to enter gfxoff in certain user cases.
