this was changed recently, with a patch for the EEE stuff , see here: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?h=v5.0-rc7&id=e35e26b26e955c53e61c154ba26b9bb15da6b858 before that the IRQ stuff was differently. I tried to revert this patch via git locally, but had no success ( i guess git tried to revert this patch on the server :-P) regards, Simon
