      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)

       "Here is a set of patches that revert all of the changes done to the
        pl2303 USB serial driver in the 3.12-rc timeframe, as it turns out
        they break some devices that work just fine on 3.11.  As it's not a
        good idea to break working systems, drop them all and they will be
        reworked for future kernel versions such that there is no breakage.

        and a new device id for the ftdi_sio driver as well"

      memcg: remove incorrect underflow check · 6920a1bd
      Greg Thelen authored
      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.
      
      Fixes: 3ea67d06 ("memcg: add per cgroup writeback pages accounting")

      USB: Maintainers change for usb serial drivers · f896b796
      Greg KH authored
      Johan has been conned^Wgracious in accepting the maintainership of the
      USB serial drivers, especially as he's been doing all of the real work
      for the past few years.
      
      At the same time, remove a bunch of old entries for USB serial drivers
      that don't make sense anymore, given that the developers are no longer
      around, and individual driver maintainerships for tiny things like this
      is pretty pointless.
