From 6e799cb69a70eedbb41561b750f7180c12cff280 Mon Sep 17 00:00:00 2001 From: Thomas Gleixner Date: Wed, 18 Nov 2020 20:48:39 +0100 Subject: mm/highmem: Provide and use CONFIG_DEBUG_KMAP_LOCAL CONFIG_KMAP_LOCAL can be enabled by x86/32bit even if CONFIG_HIGHMEM is not enabled for temporary MMIO space mappings. Provide it as a seperate config option which depends on CONFIG_KMAP_LOCAL and let CONFIG_DEBUG_HIGHMEM select it. This won't increase the debug coverage of this significantly but it paves the way to do so.
