Looking over the ACPI config options,
it feels like time for some spring cleaning...

In 2.4 it was common to build with CONFIG_ACPI_BOOT but without CONFIG_ACPI to enable HT. Nobody really does that much in 2.6; and actually quite a number of people of complained about how bogus it is.

I'd like to make everything with "ACPI" in it
depend on CONFIG_ACPI. (except the e820 stuff,
which isn't conditionally compiled, even though
it is part of ACPI)

I think we can also get rid of
CONFIG_ACPI_BOOT
CONFIG_ACPI_INTERPRETER
CONFIG_ACPI_BUS
CONFIG_ACPI_EC

as they're synonymous with CONFIG_ACPI.

I'd like to see the /proc stuff go away,
and the CONFIG_ACPI_SLEEP_PROC_FS should go with it.

comments?
thanks,

Looking over the ACPI config options,

I'd like to see the /proc stuff go away,

And where would they be located then?
I see lots of directories in /sys/firmware/acpi/namespace/ACPI

but no ascii files

I think we can also get rid of
CONFIG_ACPI_BOOT
CONFIG_ACPI_INTERPRETER
CONFIG_ACPI_BUS
CONFIG_ACPI_EC
as they're synonymous with CONFIG_ACPI.

I did the above except left CONFIG_ACPI_EC alone for now; plus I deleted
CONFIG_ACPI_POWER
CONFIG_ACPI_SYSTEM.
and stale references to CONFIG_SGI_SN

patch attached.

cheers,
