Merge tag 'overflow-v4.18-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull more overflow updates from Kees Cook:
 "The rest of the overflow changes for v4.18-rc1.

  This includes the explicit overflow fixes from Silvio, further
  struct_size() conversions from Matthew, and a bug fix from Dan.

  But the bulk of it is the treewide conversions to use either the
  2-factor argument allocators (e.g. kmalloc(a * b, ...) into
  kmalloc_array(a, b, ...) or the array_size() macros (e.g. vmalloc(a *
  b) into vmalloc(array_size(a, b)).

  Coccinelle was fighting me on several fronts, so I've done a bunch of
  manual whitespace updates in the patches as well.

  Summary:

   - Error path bug fix for overflow tests (Dan)

   - Additional struct_size() conversions (Matthew, Kees)

   - Explicitly reported overflow fixes (Silvio, Kees)

   - Add missing kvcalloc() function (Kees)

   - Treewide conversions of allocators to use either 2-factor argument
     variant when available, or array_size() and array3_size() as needed
     (Kees)"
