Yes, kaslr randomizes the direct map. We have seen problems with it in the past relative to setting up pmem mappings. We fixed one such bug with this commit: fc5f9d5f151c x86/mm: Fix boot crash caused by incorrect loop count calculation in sync_global_pgds() ...but it appears we may have another bug in this area. _______________________________________________ Linux-nvdimm mailing list Linux-nvdimm@lists.01.org https://lists.01.org/mailman/listinfo/linux-nvdimm
