From e23c45976f82ac789469c37e4d5a72ea2ce30bba Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Thu, 4 Jun 2020 16:47:34 -0700 Subject: arch/kunmap: remove duplicate kunmap implementations MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit All architectures do exactly the same thing for kunmap(); remove all the duplicate definitions and lift the call to the core. This also has the benefit of changing kmap_unmap() on a number of architectures to be an inline call rather than an actual function.
