Subject: [GIT PULL 3/6] KVM: s390: arm64: Turn vcpu->arch.pause into a counter
Date: Fri, 6 Nov 2026 17:49:55 +0100 [thread overview]
Message-ID: <20261106164958.431978-4-borntraeger@linux.ibm.com> (raw)
In-Reply-To: <20261106164958.431978-1-borntraeger@linux.ibm.com>
From: Steffen Eiden <seiden@linux.ibm.com>
The s390 arm64 vcpu struct mirrors arm64's kvm_vcpu_arch. When commit
e64309198eda2 ("KVM: arm64: Turn vcpu->arch.pause into a counter")
changed the type of kvm_vcpu_arch.pause from bool to atomic_t, the merge
into this tree missed the s390 copy, leaving it out of sync.
Nothing on the s390 side accesses vcpu->arch.pause yet, so this has
no functional effect. Align the type to keep the mirror identical to
its arm64 counterpart.
Fixes: e6c329180d1d ("KVM: s390: arm64: Introduce host definitions")
