[ again, this time with Sasha's new e-mail address, and updated ] Build failures in v3.18.38 and 4.1.29: mips builds: 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. sparc64 builds: mm/init_64.c: In function 'bootmem_init_numa': arch/sparc/mm/init_64.c:1311:4: error: 'numa_latency' undeclared Caused by 0396a871c4e3 ("sparc64: Fix numa node distance initialization"). 'numa_latency' does not exist in 3.18 and 4.1. It was introduced upstream with commit 52708d690b8be ("sparc64: Fix numa distance values").
