As far as I can tell, the last user of config ACPI_PROCFS got removed in v2.6.38, with commit cef6e8a3790d6bdc305496629c357a56001d59a6 ("ACPI processor: remove processor throttling control procfs I/F"). I must admit I can't really wrap my head around the (former) purpose of ACPI_PROCFS. So perhaps someone can tell me whether its Kconfig entry is still needed.
