Subject[PATCH v1 1/1] s390/protvirt: fix compilation issue
Date
The kernel fails to compile with CONFIG_PROTECTED_VIRTUALIZATION_GUEST
set but CONFIG_KVM unset.

This patch fixes the issue by making the needed variable always available.

Fixes: a0f60f8431999bf5 ("s390/protvirt: Add sysfs firmware interface for Ultravisor information")
