    scripts/kallsyms: filter symbols not in kernel address space · f6537f2f
    Ming Lei authored
    This patch uses CONFIG_PAGE_OFFSET to filter symbols which
    are not in kernel address space because these symbols are
    generally for generating code purpose and can't be run at
    kernel mode, so we needn't keep them in /proc/kallsyms.
    
    For example, on ARM there are some symbols which may be
    linked in relocatable code section, then perf can't parse
    symbols any more from /proc/kallsyms, this patch fixes the
    problem (introduced b9b32bf7)
