The following looks bogus:

 config KEXEC
        bool "kexec system call (EXPERIMENTAL)"
-       depends on EXPERIMENTAL
+       depends on EXPERIMENTAL && (!X86_VOYAGER && SMP)

The dependencies do now say that KEXEC is only offered for machines that are _both_ non-Voyager and SMP.

Is the problem you wanted to express that a non-SMP Voyager config didn't compile?

Whoops, that should be

depends on EXPERIMENTAL && !(X86_VOYAGER && SMP)

Voyager SMP builds don't compile with kexec(), and it isn't clear how to shootdown CPUs using NMIs without an APIC.

 	  kexec is a system call that implements the ability to shutdown your
 	  current kernel, and to start another kernel.  It is like a reboot
