Subject: [PATCH 02/10] alpha: Require kernel version 2.6.0.
Date: Thu, 09 Feb 2012 04:29:00 -0000 [thread overview]
Message-ID: <1328761745-24481-3-git-send-email-rth@twiddle.net> (raw)
In-Reply-To: <1328761745-24481-1-git-send-email-rth@twiddle.net>
The minimum version that supports TLS. Also avoids having to
fix the build for ancient __ASSUME_* settings.
