[PATCH] kvm: (ppc) stub out more functions in order to permit kernel to build

[Phil Carmody]

Build failure mentioned by Stephen Rothwell here:
http://www.mail-archive.com/linuxppc-dev@lists.ozlabs.org/msg65408.html

Traced to:
commit f445f11eb2cc -"KVM: allow host header to be included even for !CONFIG_KVM"

This patch permits the build to progress by stubbing out the two functions
that it fell over on. I have no idea if that's even vaguely appropriate.

This has been .c->.o compile tested only, as g5_defconfig FTB elsewhere.
