[uml-devel] [patch 06/12] uml: disable more hardware kconfig opt and rename USERMODE to UML
|
From: <bla...@ya...> - 2005-03-22 17:56:23
|
From: Paolo 'Blaisorblade' Giarrusso <bla...@ya...>
Disable some hardware-only configuration options when configuring for ARCH=um.
By the way, we rename CONFIG_USERMODE to CONFIG_UML, as requested some time ago by the
UML maintainer Jeff Dike.
We also update defconfig as a consequence of all this.
Signed-off-by: Paolo 'Blaisorblade' Giarrusso <bla...@ya...>

Usually, you have to use modules compiled with your kernel.
Saying Y here makes it sometimes possible to use modules
