Subject: [PATCH] drivers: acpi: make ACPI_PROCFS_POWER X86 only

The ACPI procfs power interface is initialized by compilation units
that are only selectable on X86 platforms. Since its usage is
deprecated and it cannot even be used on platforms other than X86
it should be compiled in only on X86 platforms.

This patch makes CONFIG_ACPI_PROCFS_POWER dependent on X86, so
that other architectures are prevented from compiling it in for
no purpose.

Lan, Rafael,

I do not see any reason why this option is allowed to be selected
on platforms other than X86, so let's make it X86 only. Please let
me know what you think, thanks.

Lorenzo
