Subject: ACPI: simplify module_param namespace
From: Rusty Russell <rusty@xxxxxxxxxxxxxxx>
Impact: cleanup
Rather than overriding MODULE_PARAM_PREFIX, build via acpi.o so
KBUILD_MODNAME is set to "acpi".
This is the logical way to do it, even though acpi cannot be a module
due to these config options being bool. Those parts of ACPI which can
be modular are not built into the acpi "module".

Rusty, thanks for the patch.
Here is the version i checked in, after merging on top of the acpi tree
(ec no longer depends on link order)
