Subject: [PATCH 0/5] simple sort swap function usage improvements

This is the logical continuation of sort improvements by George Spelvin
"lib/sort & lib/list_sort: faster and smaller" series
(added to the linux-next really recently).

Patches from 1 to 4 replace simple swap functions with the built-in
(which is now much faster) and grouped by subsystem (after that only
3 files implement custom swap - arch/x86/kernel/unwind_orc.c,
kernel/jump_label.c and lib/extable.c).

Patch #5 replaces the int type with the size_t type of the size argument
in the swap function.

Andrey Abramov (5):
  arch/arc: unwind.c: replace swap function with built-in one
  powerpc: module_[32|64].c: replace swap function with built-in one
  ocfs2: dir,refcounttree,xattr: replace swap functions with built-in
    one
  ubifs: find.c: replace swap function with built-in one
  Lib: sort.h: replace int size with size_t size in the swap function
