From 079f85e624189292d1c818b47764916bf8cf84a8 Mon Sep 17 00:00:00 2001 From: Michal Marek Date: Tue, 12 Apr 2011 13:30:24 +0200 Subject: x86, build: Do not set the root_dev field in bzImage This has been obsoleted by the root= commandline and the rdev utility for many, many years. People who still depend on this will surely have a copy of the rdev utility around, the rest of the world gets rid of another piece of buildhost-dependent data in the build. Thanks to Paul Bolle for the build.c cleanup. Cc: Paul Bolle Signed-off-by: Michal Marek Link: http://lkml.kernel.org/r/1302607824-24699-1-git-send-email-mmarek@suse.cz Signed-off-by: H.
