Subject: [PATCH v2 03/24] arm64: Make cpu_logical_map() take unsigned int
Date: Mon, 16 Nov 2020 20:42:57 +0000 [thread overview]
Message-ID: <20201116204318.63987-4-dbrazdil@google.com> (raw)
In-Reply-To: <20201116204318.63987-1-dbrazdil@google.com>
CPU index should never be negative. Change the signature of
(set_)cpu_logical_map to take an unsigned int.
