Subject: Re: [PATCH v4 00/14] ACPI NUMA support for ARM64
Date: Tue, 19 Apr 2016 11:44:01 -0700 [thread overview]
Message-ID: <57167C71.5010800@caviumnetworks.com> (raw)
In-Reply-To: <1461014052-30788-1-git-send-email-ddaney.cavm@gmail.com>
There is a build problem on ia64 that slipped by. It is easy to
correct, so I will have to send another version of the patches.
Sorry for the noise,
David Daney
