Subject: [PATCH 1/2] x86/hvm: make sure HVM_PARAM_[BUF]IOREQ_PFN can only be set once
Date: Fri, 5 Oct 2018 14:43:33 +0100 [thread overview]
Message-ID: <20181005134334.2645-2-paul.durrant@citrix.com> (raw)
In-Reply-To: <20181005134334.2645-1-paul.durrant@citrix.com>
These parameters should have always been in the 'set once' category
but this has, so far, not been enforced.
