Message-Id: <20240131233056.10845-5-pbonzini@redhat.com>
Date: Wed, 31 Jan 2024 18:30:52 -0500
From: Paolo Bonzini <pbonzini@...hat.com>

Subject: [PATCH 4/8] KVM: s390: move s390-specific structs to uapi/asm/kvm.h
While this in principle breaks the appearance of KVM_S390_* ioctls on architectures
other than s390, this seems unlikely to be a problem considering that there are
already many "struct kvm_s390_*" definitions in arch/s390/include/uapi.
