Hi Petr, You're preaching to the choir, man... [PATCH 00/10] Enhance /dev/mem to allow read/write of arbitrary physical addresses https://lkml.org/lkml/2011/6/17/81 and especially your response to Ingo: https://lkml.org/lkml/2011/6/17/106 I fought and lost that war within Red Hat years ago, but I wish you the best of luck!
