[PATCH v4 2/4] KVM: x86: Use vector-hashing to deliver lowest-priority interrupts

2016-01-25 Thread Feng Wu
Use vector-hashing to deliver lowest-priority interrupts, As an example, modern Intel CPUs in server platform use this method to handle lowest-priority interrupts. Signed-off-by: Feng Wu --- v4: - Stylistic changes v3: - Fix a bug for sparse topologies, in that case, vcpu_id is not equal to the
