From dc33db7c338e1a7a4a7cb94d73745c8ca54b1ac8 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Wed, 15 Jun 2016 17:45:44 +0200 Subject: [PATCH] Kbuild: avoid duplicate include path arch/$(hdr-arch)/include/generated/uapi is included twice in the header search path, which is unnecessary, so this changes the top-level Makefile to drop the second instance by filtering out everything from USERINCLUDE that was already part of LINUXINCLUDE. This should have very little effect other than making the 'make V=1' output slightly smaller and making the build time faster by a miniscule amount, but it seems to be cleaner.
