Venkatesh Srinivas 82e9c84d87 KVM: Remove kvm_make_all_cpus_request_except() ... Remove kvm_make_all_cpus_request_except() as it effectively has no users, and arguably should never have been added in the first place. Commit 54163a346d ("KVM: Introduce kvm_make_all_cpus_request_except()") added the "except" variation for use in SVM's AVIC update path, which used it to skip sending a request to the current vCPU (commit 7d611233b0 ("KVM: SVM: Disable AVIC before setting V_IRQ")). But the AVIC usage of kvm_make_all_cpus_request_except() was essentially a hack-a-fix that simply squashed the most likely scenario of a racy WARN without addressing the underlying problem(s). Commit f1577ab214 ("KVM: SVM: svm_set_vintr don't warn if AVIC is active but is about to be deactivated") eventually fixed the WARN itself, and the "except" usage was subsequently dropped by df63202fe5 ("KVM: x86: APICv: drop immediate APICv disablement on current vCPU"). That kvm_make_all_cpus_request_except() hasn't gained any users in the last ~3 years isn't a coincidence. If a VM-wide broadcast *needs* to skip the current vCPU, then odds are very good that there is underlying bug that could be better fixed elsewhere.
