linux.git/arch/xtensa/include/asm/fixmap.h, branch v3.15 Linux kernel source tree xtensa: add HIGHMEM support 2014-04-06T17:29:21+00:00 Max Filippov jcmvbkbc@gmail.com 2014-02-03T22:17:09+00:00 65559100655c6ed6ce2e17ffc8d4f3852bc2858a 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.
