Build Failures Detected:

mips: gcc version 6.3.0 (GCC)

Errors summary:

  60  arch/mips/kernel/setup.c:439:8: error: implicit declaration of function 'PHYS_PFN' [-Werror=implicit-function-declaration]

All mips builds failed with this error, apparently caused by the backport of d9b5b658210f2 ("MIPS: init: Ensure bootmem does not corrupt reserved memory").

The following change: 8f235d1a3eb71 ('mm: add PHYS_PFN, use it in __phys_to_pfn()') needs to be backported prior to d9b5b658210f2 to add the missing macro definition.

Thanks, now queued up, hopefully this fixes the build issues.
