ACPI: use LNXCPU, not ACPI_CPU, for Linux-specific processor _HID
ACPI_PROCESSOR_OBJECT_HID is a synthetic _HID that Linux generates for "Processor" definitions. Unlike "Device" definitions, "Processor" definitions do not have a _HID in the namespace, so we generate a fake _HID. By convention, all these fake _HIDs begin with "LNX". This does change the user-visible _HID for "Processor" objects -- previously, we used "ACPI_CPU" and this changes that to "LNXCPU", which starts with "LNX" as do all the other made-up _HIDs. This change is visible in processor filenames and "hid" files under /sys/devices/LNXSYSTM:00/. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
