+Subject: MIPS: increase MAX_PHYSMEM_BITS on Loongson 3 only
+Bug-Debian: https://bugs.debian.org/764223
+Forwarded: no
+
+Commit c4617318 broke Loongson-2 support and maybe even more by increasing
+the value of MAX_PHYSMEM_BITS. At it is currently only needed on
+Loongson-3, define it conditionally.
+
+Note: this should be replace by upstream fix when available.
