>=linux-4.1: build fails w/_PAGE_GLOBAL_SHIFT redefined errors in pgtable-bits.h
this works in linux-4.0, but starting with 4.1, i'm seeing:

make[2]: *** [arch/mips/kernel/cpu-probe.o] Error 1
make[1]: *** [arch/mips/kernel] Error 2
make: *** [arch/mips] Error 2
this warning hits many times, but this one is actually fatal
looks like it's due to:
be0c37c985eddc46d0d67543898c086f60460e2e MIPS: Rearrange PTE bits into fixed positions.
my config is attached

MIPS: pgtable-bits.h: Correct _PAGE_GLOBAL_SHIFT build failure
can that get included in linux-4.1 and linux-4.2 stable ? -mike
