So I think I have a fix for these, but I still would like the actual
.config so that I can be sure.

I can't reproduce this one.  MSR_GS is defined in reg_booke.h.
fsl_hypervisor.c should not be compiled on a non-booke platform.  I don't
know if the fix is to add this to fsl_hypervisor.c:

	#include <asm/reg_booke.h>

or if I should update the Kconfig:

config FSL_HV_MANAGER
	tristate "Freescale hypervisor management driver"
	depends on FSL_SOC

to

	depends on FSL_BOOKE

or maybe

	depends on FSL_BOOKE && FSL_SOC
