Seems ok, but I'll reinstate this:
#if BITS_PER_LONG != __BITS_PER_LONG
#error Inconsistent word size. Check asm/bitsperlong.h
#endif
And now I'm rerunning these tests, that without the above check
produces:
# dm
alpine:3.4: Ok
android-ndk:r12b: Ok
centos:5: perf: Ok, objtool: FAIL # But this one predates this patch, I'll fix it
centos:6: Ok
centos:7: Ok
debian:7: Ok
debian:8: Ok
debian:experimental: Ok
fedora:21: Ok
fedora:22: Ok
fedora:23: Ok
fedora:24: Ok
fedora:rawhide: Ok
opensuse:13.2: Ok
opensuse:42.1: Ok
ubuntu:14.04.4: Ok
