From d84876f9f8042d5536050b83674c4f348ca3c4df Mon Sep 17 00:00:00 2001 From: Jan Engelhardt Date: Thu, 3 Jan 2008 23:33:44 +0100 Subject: [PATCH] kconfig: allow overriding symbols Allow config variables in .config to override earlier ones in the same file. In other words, # CONFIG_SECURITY is not defined CONFIG_SECURITY=y will activate it. This makes it a bit easier to do cat original-config myconfig myconfig2 ... >.config; and run *config as expected.
