Description Baoquan He 2017-03-02 06:38:18 UTC
Description of problem:
User space kexec-tools will search /proc/kallsyms for page_offset_base anyway to try to get page_offset. While page_offset_base definition and exporting codes are only available when mm KASLR code is compiled in kernel, otherwise it can't search anything and this is positive behaviour, there shoud be no error message printed out. Need fix it out.
