| Subject: [PATCH] perf: Provide kmap_atomic_direct for !CONFIG_HIGHMEM |
| |
| commit 327735e61bcee29f59a6fd053db894cdddff987e in tip. |
| |
| ddeca6231cbdebd0fa0f1bac816f1e1e6eae485b doesn't compile, if CONFIG_HIGHMEM |
| is not enabled, because kmap_atomic_direct and kunmap_atomic_direct are |
| undefined. |
