Hi,



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
