Subject: [Xen-devel] [PATCH v2 53/55] x86/mm: drop old page table APIs
Date: Mon, 30 Sep 2019 11:33:45 +0100	[thread overview]
Message-ID: <df032470e631f8f3e8cdf7b1289e1ca204692652.1569833766.git.hongyax@amazon.com> (raw)
In-Reply-To: <cover.1569833766.git.hongyax@amazon.com>

From: Wei Liu <wei.liu2@citrix.com>

Now that we've switched all users to the new APIs, the old ones aren't
needed anymore.
