Subject: [PATCH 0/5] Remove duplicated kmap code

From: Ira Weiny <ira.weiny@...el.com>

The kmap infrastructure has been copied almost verbatim to every architecture.
This series consolidates obvious duplicated code.  (k[un]map_atmoic has some
additional duplication between some of the architectures but the differences
were such to not warrant further changes.)

0day built successfully to cover all the architectures I can't readily build.

Ira Weiny (5):
  arch/kmap: Remove BUG_ON()
  arch/kmap: Remove redundant arch specific kmaps
  arch/kunmap: Remove duplicate kunmap implementations
  arch/kmap_atomic: Consolidate duplicate code
  arch/kunmap_atomic: Consolidate duplicate code
