From 90ac086bca100c654e84637d9990567f436cab23 Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Thu, 8 Jan 2015 16:16:39 +0100 Subject: [PATCH] Makefile: include arch/*/include/generated/uapi before .../generated The introduction of the uapi directories in v3.7-rc1 moved some of the generated headers from arch/*/include/generated to the uapi directory, keeping the #include directives intact. This creates a problem when bisecting, because the unversioned files are not cleaned automatically by git and the compiler might include stale headers as a result. Instead of cleaning them in the Makefiles, promote arch/*/include/generated/uapi in the search path. Under normal circumstances, there is no overlap between this uapi subdirectory and its parent, so the include choices remain the same. We keep arch/*/include/generated/uapi in the USERINCLUDE variable so that it is usable standalone. Note that we cannot completely swap the order of the uapi and kernel-only directories, since the headers in include/uapi/asm-generic are meant to be wrapped by their include/asm-generic counterparts when building kernel code.
