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.

I'm sorry, it mush have gotten lost in the email switch. I'll revert
that commit for the next stable release and hurry that up.


Thanks,
Sasha
