From 36cbbe5eb9857730768aa5f54ad94d69e0b2133d Mon Sep 17 00:00:00 2001 From: Benjamin LaHaise Date: Wed, 15 Feb 2006 15:17:35 -0800 Subject: [PATCH] [PATCH] kbuild: revert "fix make -jN with multiple targets with O=..." Commit 296e0855b0f9a4ec9be17106ac541745a55b2ce1: "kbuild: fix make -jN with multiple targets with O=..." causes a ~95% increase in build time for the kernel. Before: 4m21s after: 8m1.403s. Can we revert this until another approach is found?
