      scripts/kallsyms: filter symbols not in kernel address space · f6537f2f
      Ming Lei 提交于
      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)

      memcg: remove incorrect underflow check · 6920a1bd
      Greg Thelen 提交于
      When a memcg is deleted mem_cgroup_reparent_charges() moves charged
      memory to the parent memcg.  As of v3.11-9444-g3ea67d06 "memcg: add per
      cgroup writeback pages accounting" there's bad pointer read.  The goal
      was to check for counter underflow.  The counter is a per cpu counter
      and there are two problems with the code:
      
       (1) per cpu access function isn't used, instead a naked pointer is used
           which easily causes oops.
       (2) the check doesn't sum all cpus
      
      Test:
        $ cd /sys/fs/cgroup/memory
        $ mkdir x
        $ echo 3 > /proc/sys/vm/drop_caches
        $ (echo $BASHPID >> x/tasks && exec cat) &
        [1] 7154
        $ grep ^mapped x/memory.stat
        mapped_file 53248
        $ echo 7154 > tasks
        $ rmdir x
        <OOPS>
      
      The fix is to remove the check.  It's currently dangerous and isn't
      worth fixing it to use something expensive, such as
      percpu_counter_sum(), for each reparented page.  __this_cpu_read() isn't
      enough to fix this because there's no guarantees of the current cpus
      count.  The only guarantees is that the sum of all per-cpu counter is >=
      nr_pages.
