From c45166be3cc666ce88fe623ad79276c943e74eff Mon Sep 17 00:00:00 2001 From: Paolo 'Blaisorblade' Giarrusso Date: Sun, 1 May 2005 08:58:54 -0700 Subject: [PATCH] [PATCH] uml: support AES i586 crypto driver We want to make possible, for the user, to enable the i586 AES implementation. This requires a restructure. - Add a CONFIG_UML_X86 to notify that we are building a UML for i386. - Rename CONFIG_64_BIT to CONFIG_64BIT as is used for all other archs - Tell crypto/Kconfig that UML_X86 is as good as X86 - Tell it that it must exclude not X86_64 but 64BIT, which will give the same results. - Tell kbuild to descend down into arch/i386/crypto/ to build what's needed.
