- * sequences. This enum represents accepted values for the x86

- *
- * These enums should only ever be used by x86 code, and the code that uses
- * it should be well contained and compartmentalized.
- *
- * KVM and Xen HVM do not have a subarch as these are expected to follow

- * 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
