[PATCH v3 1/2] KVM: nVMX: Drop a redundant call to vmx_get_intr_info()
From: Sean Christopherson
Date: Tue Apr 21 2020 - 03:53:38 EST
Drop nested_vmx_l1_wants_exit()'s initialization of intr_info from
vmx_get_intr_info() that was inadvertantly introduced along with the
caching mechanism. EXIT_REASON_EXCEPTION_NMI, the only consumer of
intr_info, populates the variable before using it.
Fixes: bb53120d67cdb ("KVM: VMX: Cache vmcs.EXIT_INTR_INFO using arch avail_reg flags")
