This is cbecause ea642c3216cb ("drm/ttm: add io_mem_pfn callback") is incomplete: the hisilicon hibmc driver does not contain the callback and so the kernel tries to execute code at NULL. [Fix] There is a discussion and potential fix at https://lists.freedesktop.org/archives/dri-devel/2017-November/159002.html The fix hasn't landed yet and it looks like they're going to re-engineer the entire section instead. Rather than wait for that and deal with the massive regression potential, the fix I have picked to submit is very very minimal and touches only hibmc. [Regression Potential] Minimal - fix only touches hibmc driver. Tested on D05 board. [Testcase] Install patched kernel, try to start X. If it succeeds, the fix works. If there's a kernel splat, the fix does not work. [Notes] HiSilicon would really like this fix in Artful in such time so that when the next 16.04 point release ships in February, the HWE kernel will work with Xorg.
