+Subject: Revert "MIPS: Loongson64: Enable DMA noncoherent support"
+
+From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
+
+This reverts commit 3ee7e2faef87594228eb2622f8c25c0495ea50a1 which is
+commit edc0378eee00200a5bedf1bb9f00ad390e0d1bd4 upstream.
+
+There are reports of this causing build issues, so revert it from the
+5.10.y tree for now.
