Subject: [PATCH 04/13] KVM: monolithic: x86: handle the request_immediate_exit variation
Date: Mon, 4 Nov 2019 17:59:52 -0500 [thread overview]
Message-ID: <20191104230001.27774-5-aarcange@redhat.com> (raw)
In-Reply-To: <20191104230001.27774-1-aarcange@redhat.com>
request_immediate_exit is one of those few cases where the pointer to
function of the method isn't fixed at build time and it requires
special handling because hardware_setup() may override it at runtime.
