Are you sure? On the Linus's repo I have: config XEN_MCE_LOG bool "Xen platform mcelog" depends on XEN_DOM0 && X86_64 && X86_MCE Anyway, the MCE interface in the hypervisor is implemented in arch/x86 not in common code. >>> +CONFIG_XEN_HAVE_PVMMU=y >> >> >> We don't have PVMMU support on ARM.

CONFIG_XEN_HAVE_PVMMU can't be selected by the user. It's automatically added per platform (for instance see arch/x86/xen/Kconfig). So maybe it should not even appear in the one of the fragment configs?
