Three patchlets to correct HIGHMEM64G and CMPXCHG64 dependencies in Kconfig
when CPU selections are explicitely set to M586 or M686.

Thanks,

	tglx

------------------>
Matthew Whitehead (3):
      x86/Kconfig: Add missing i586-class CPUs to the X86_CMPXCHG64 Kconfig group
      x86/Kconfig: Exclude i586-class CPUs lacking PAE support from the HIGHMEM64G Kconfig group
      x86/Kconfig: Explicitly enumerate i686-class CPUs in Kconfig
