From 53e6892c0411006848882eacfcfea9e93681b55d Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Tue, 5 Apr 2011 14:32:30 +0200 Subject: kbuild: Allow to override LINUX_COMPILE_BY and LINUX_COMPILE_HOST macros Make it possible to override the user@host string displayed during boot and in /proc/version by the environment variables KBUILD_BUILD_USER and KBUILD_BUILD_HOST. Several distributions patch scripts/mkcompile_h to achieve this, so let's provide an official way. Also, document the KBUILD_BUILD_TIMESTAMP variable while at it.
