Heiko Carstens fc31fb6f36 KVM: s390: get rid of register asm usage
[ Upstream commit 4fa3b91bdee1b08348c82660668ca0ca34e271ad ]

Using register asm statements has been proven to be very error prone,
especially when using code instrumentation where gcc may add function
calls, which clobbers register contents in an unexpected way.

Therefore get rid of register asm statements in kvm code, even though
there is currently nothing wrong with them. This way we know for sure
that this bug class won't be introduced here.
