/**
 * enum x86_hardware_subarch - x86 hardware subarchitecture
 *
 * The x86 hardware_subarch and hardware_subarch_data were added as of the x86
 * boot protocol 2.07 to help distinguish and support custom x86 boot
 * sequences. This enum represents accepted values for the x86
 * hardware_subarch.  Custom x86 boot sequences (not X86_SUBARCH_PC) do not
 * have or simply *cannot* make use of natural stubs like BIOS or EFI, the
 * hardware_subarch can be used on the Linux entry path to revector to a
 * subarchitecture stub when needed. This subarchitecture stub can be used to
 * set up Linux boot parameters or for special care to account for nonstandard
 * handling of page tables.
 *
 * These enums should only ever be used by x86 code, and the code that uses
 * it should be well contained and compartamentalized.
 *
 * KVM and Xen HVM do not have a subarch as these are expected to follow
 * standard x86 boot entries. If there is a genuine need for "hypervisor" type
 * that should be considered separately in the future. Future guest types
 * should seriously consider working with standard x86 boot stubs such as
 * the BIOS or EFI boot stubs.
 *
 * WARNING: this enum is only used for legacy hacks, for platform features that
 *	    are not easily enumerated or discoverable. You should not ever use
 *	    this for new features.
 *
 * @X86_SUBARCH_PC: Should be used if the hardware is enumerable using standard
 *	PC mechanisms (PCI, ACPI) and doesn't need a special boot flow.
 * @X86_SUBARCH_LGUEST: Used for x86 hypervisor demo, lguest, deprecated
 * @X86_SUBARCH_XEN: Used for Xen guest types which follow the PV boot path,
 * 	which start at __asm__ startup_xen() entry point and later jump to the C
 * 	xen_start_kernel() entry point. Both domU and dom0 type of guests are
 * 	currently supportd through this PV boot path.
 * @X86_SUBARCH_INTEL_MID: Used for Intel MID (Mobile Internet Device) platform
 *	systems which do not have the PCI legacy interfaces.
 * @X86_SUBARCH_CE4100: Used for Intel CE media processor (CE4100) SoC for
 * 	for settop boxes and media devices, the use of a subarch for CE4100
 * 	is more of a hack...
