Subject: [PATCH 2/4] arm64: Fix the update_vsyscall() prototype
Date: Tue, 16 Oct 2012 17:46:38 +0100 [thread overview]
Message-ID: <1350406000-30882-3-git-send-email-catalin.marinas@arm.com> (raw)
In-Reply-To: <1350406000-30882-1-git-send-email-catalin.marinas@arm.com>
With commit 576094b7 (time: Introduce new GENERIC_TIME_VSYSCALL) the old
update_vsyscall() prototype is no longer available. This patch updates
the arm64 port.
