Subject: [PATCH 5/6] MIPS: net: BPF: Use BPF register names to describe the ABI
Date: Thu, 4 Jun 2015 11:56:15 +0100	[thread overview]
Message-ID: <1433415376-20952-6-git-send-email-markos.chandras@imgtec.com> (raw)
In-Reply-To: <1433415376-20952-1-git-send-email-markos.chandras@imgtec.com>

Use the BPF register names instead of the arch register names to
document how the ABI is structured.
