KVM: x86: Plumb "force_immediate_exit" into kvm_entry() tracepoint

Browse source

[ Upstream commit 9c9025ea00 ]

Annotate the kvm_entry() tracepoint with "immediate exit" when KVM is
forcing a VM-Exit immediately after VM-Enter, e.g. when KVM wants to
inject an event but needs to first complete some other operation.
Knowing that KVM is (or isn't) forcing an exit is useful information when
debugging issues related to event injection.
