Re:mips builds failing in v3.18.38 and v4.1.29

Hi,

I have already told Sasha that "MIPS: Reserve nosave data for hibernation" should not be backported to 4.1/3.18. But he has no response.

Subject:  mips builds failing in v3.18.38 and v4.1.29
 
Sorry I didn't notice earlier - my 3.18/4.1 build scripts were broken.

arch/mips/kernel/setup.c: In function 'arch_mem_init':
arch/mips/kernel/setup.c:689:2: error: implicit declaration of function 'reserve_bootmem_region'

Offending commit is 1dd0964204277108e ("MIPS: Reserve nosave data for hibernation").
It fixes a bug which does not exist in 3.18 / 4.1, in turn causing all mips builds in 3.18
and 4.1 to fail.
