Pull sysfs module section fix from Kees Cook:
 "Fix sysfs module section output overflow.

  About a month after my kallsyms_show_value() refactoring landed, 0day
  noticed that there was a path through the kernfs binattr read handlers
  that did not have PAGE_SIZEd buffers, and the module "sections" read
  handler made a bad assumption about this, resulting in it stomping on
  memory when reached through small-sized splice() calls.

  I've added a set of tests to find these kinds of regressions more
  quickly in the future as well"
