Reverting above pfn rework patch fixes that problem, so you might want to remove that patch from the patch queue for now.Perhaps this one got applied too soon? commit 730b8dfe016dd1e91f73d8d3e6724da91397171c Author: Ralf Baechle <ralf@xxxxxxxxxxxxxx> Date: Fri Dec 28 15:18:02 2012 +0100 MIPS: page.h: Remove now unnecessary #ifndef __ASSEMBLY__ wrapper.

Actually, you are on the right track, only in the opposite direction. The problem is that commit 8b9232141b changed #define pfn_valid ... to static inline pfn_valid() in arch/mips/include/asm/page.h. In the 3.4 kernel the file _is_ still included from assembler code. This obviously doesn't work. Fix would be to surround the new static inline function with #ifndef __ASSEMBLY__. With this change, "mips allmodconfig" compiles with the 3.4 kernel. It should be a safe change, since the static inline will never be used from assembler code. Question is if that would be acceptable as back-port of 8b9232141b to 3.4. Greg, any comments ? If it is ok I can submit a back-port request with the modified patch to -stable. That would be one more build fixed, three to go (arm:allmodconfig, sparc32:defconfig, and sparc64:allmodconfig).
