Merge tag 'kmalloc_obj-v7.0-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux

Pull kmalloc_obj updates from Kees Cook:
 "Introduce the kmalloc_obj* family of APIs for switching to type-based
  kmalloc allocations, away from purely size-based allocations.
  Discussed on lkml, with you, and at Linux Plumbers. It's been in -next
  for the entire dev cycle.

  Before the merge window closes, I'd like to send the treewide
  change (generated from the Coccinelle script included here), which
  mechanically converts almost 20k callsites from kmalloc* to
  kmalloc_obj*:

   8007 files changed, 19980 insertions(+), 20838 deletions(-)

  This change needed fixes for mismatched types (since now the return
  type from allocations is a pointer to the requested type, not "void
  *"), and I've been fixing these over the last 4 releases.

  These fixes have mostly been trivial mismatches with const qualifiers
  or accidentally identical sizes (e.g. same object size: "struct kvec"
  vs "struct iovec", or differing pointers to pointers), but I did catch
  one case of too-small allocation.

  Summary:

   - Introduce kmalloc_obj*() family of type-based allocator APIs

   - checkpatch: Suggest kmalloc_obj family for sizeof allocations

   - coccinelle: Add kmalloc_objs conversion script"
