[PATCH 4/8] KVM: s390: move s390-specific structs to uapi/asm/kvm.h
From: Paolo Bonzini
Date: Wed Jan 31 2024 - 18:41:09 EST
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.
