Even with all you latest Kconfig fixes i get trivial build 
failures:

In fact on latest tip:x86/platform i get:

arch/x86/platform/mrst/mrst.c:306:37: error: ‘apbt_setup_secondary_clock’ undeclared (first use in this function)

Have all your recent Kconfig patches applied there, with 
probably one of them mixed up:

arch/x86/Kconfig:393:error: recursive dependency detected!

Config attached.

Thanks,
