ACPI: simplify module_param namespace 2009-04-02T20:38:11+00:00 Rusty Russell rusty@rustcorp.com.au 2009-03-11T22:37:19+00:00 5b5d9117407e790ade594687010343c5d559a1f4 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".

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".

ACPI: call acpi_debug_init() explicitly rather than as initcall 2009-03-27T16:50:29+00:00 Bjorn Helgaas bjorn.helgaas@hp.com 2009-03-24T22:50:03+00:00 84f810c33f695e020776ce66c903e0b41872f1b2 This patch makes acpi_init() call acpi_debug_init() directly. Previously, both were subsys_initcalls. acpi_debug_init() must happen after acpi_init(), and it's better to call it explicitly rather than rely on link ordering.
