I tried to apply this patch to 3.18, 4.1, 4.4, 4.7. It fails on all of
them with smaller or slightly larger conflicts.
So, I'll merge it in 4.8 without any "Cc: stable" tags, just a "Fixes:"
one for the commit introducing CONFIG_DEBUG_SET_MODULE_RONX (3.18). Once
the patch reaches mainline, could you please back-port and test it on
the stable kernel versions and send separate patches to
stable@xxxxxxxxxxxxxxx?
Thanks.
