From 65559100655c6ed6ce2e17ffc8d4f3852bc2858a Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Tue, 4 Feb 2014 02:17:09 +0400 Subject: xtensa: add HIGHMEM support Introduce fixmap area just below the vmalloc region. Use it for atomic mapping of high memory pages. High memory on cores with cache aliasing is not supported and is still to be implemented. Fail build for such configurations for now.
