From 78b6d91ec7bbfc5bcc2dd05bb2cf13c9de1dc7cd Mon Sep 17 00:00:00 2001 From: Ira Weiny Date: Thu, 4 Jun 2020 16:47:42 -0700 Subject: arch/kmap_atomic: consolidate duplicate code MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Every arch has the same code to ensure atomic operations and a check for !HIGHMEM page. Remove the duplicate code by defining a core kmap_atomic() which only calls the arch specific kmap_atomic_high() when the page is high memory.
