[Qemu-devel] [PATCH 1/2] kvm/apic: correct short memset

[Jim Meyering]

From: Jim Meyering <address@hidden>

kvm_put_apic_state's attempt to clear *kapic before setting its
bits cleared sizeof(void*) bytes (no more than 8) rather than the
intended 1024 (KVM_APIC_REG_SIZE) bytes. Spotted by coverity.
