-  This request may be made from the KVM common function kvm_vcpu_block(),

-  one of an architectural specific set of events and/or interrupts is
-  received (determined by checking kvm_arch_vcpu_runnable()).  When that
-  event or interrupt arrives kvm_vcpu_block() makes the request.  This is

-Clearing Requests
------------------
-
-Generally it only makes sense for the receiving VCPU thread to clear a
-request.  However, in some circumstances, such as when the requesting
-thread and the receiving VCPU thread are executed serially, such as when
-they are the same thread, or when they are using some form of concurrency
-control to temporarily execute synchronously, then it's possible to know
-that the request may be cleared immediately, rather than waiting for the
-receiving VCPU thread to handle the request in VCPU RUN.  The only current
-examples of this are kvm_vcpu_block() calls made by VCPUs to block
-themselves.  A possible side-effect of that call is to make the
-KVM_REQ_UNHALT request, which may then be cleared immediately when the
-VCPU returns from the call.
