Subject: [kvm-unit-tests PATCH v3 5/7] svm: convert neg shift to unsigned shift
Date: Wed, 26 Feb 2020 12:12:41 -0800 [thread overview]
Message-ID: <20200226201243.86988-6-morbo@google.com> (raw)
In-Reply-To: <20200226201243.86988-1-morbo@google.com>
Shifting a negative signed value is undefined. Use a shift of an
unsigned value instead.
