There are two options to fix the problem: o move all the s390 specific code to vcpu->wq and remove vcpu->arch.local_int.wq o move all the s390 specific code to vcpu->arch.local_int.wq This patch chooses the 2nd variant for two reasons: o s390 does not use kvm_vcpu_block but implements its own enabled wait handling. Having a separate wait_queue make it clear, that our wait mechanism is different o the patch is much smaller Report-by: Julia Lawall Signed-off-by: Christian Borntraeger Signed-off-by: Marcelo Tosatti Signed-off-by: Avi Kivity --- Reading git-diff-tree failed
