From 257edce66d31a345dff8ca9f1fd30c46e0f14058 Mon Sep 17 00:00:00 2001 From: Masahiro Yamada Date: Wed, 5 Dec 2018 16:38:35 +0900 Subject: kbuild: exploit parallel building for CONFIG_HEADERS_CHECK When CONFIG_HEADERS_CHECK is enabled, the headers_check is executed as a serialized task in the vmlinux recipe. Make it independent of vmlinux so that parallel building can process the headers_check and other build targets simultaneously.
