Subject: [PATCH 4/5] KVM: sefltests: Don't bother mapping GVA for Xen shinfo test
Date: Wed, 10 Feb 2021 10:26:08 -0800	[thread overview]
Message-ID: <20210210182609.435200-5-seanjc@google.com> (raw)
In-Reply-To: <20210210182609.435200-1-seanjc@google.com>

Don't bother mapping the Xen shinfo pages into the guest, they don't need
to be accessed using the GVAs and passing a define with "GPA" in the name
to addr_gva2hpa() is confusing.
