Subject[PATCH] KVM: x86: Force KVM_WERROR if the global WERROR is enabled
From
Force KVM_WERROR if the global WERROR is enabled to avoid pestering the
user about a Kconfig that will ultimately be ignored. Force KVM_WERROR
instead of making it mutually exclusive with WERROR to avoid generating a
config builds KVM with -Werror, but has KVM_WERROR=n.
