From: Sam Ravnborg Date: Wed, 30 Jan 2008 12:32:27 +0000 (+0100) Subject: x86: unify arch/x86/kernel/Makefile(s) X-Git-Tag: v2.6.25-rc1~1143^2~449 X-Git-Url: https://err.no/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=6b0c3d44d33e9429dbc568dc7fd3aee3774c5707;p=linux-2.6 x86: unify arch/x86/kernel/Makefile(s) Combine the 32 and 64 bit specific Makefiles in one file. While doing so link order was (almost) preserved on 32 bit but on 64 bit link order changed a lot. Patch was checked with defconfig + allyesconfig builds. The same .o files were linked in these configurations. To keep readability of the Makefiles a few Kconfig symbols was added/modified and it was checked that they were not used anywhere else.
