Subject: [PATCH 12/21] powerpc: ptrace can set DABR on both 32 and 64 bits
Date: Mon, 04 Jun 2007 15:15:47 +1000 [thread overview]
Message-ID: <20070604051552.73779DDEC4@ozlabs.org> (raw)
In-Reply-To: <1180934134.603289.870346178920.qpush@grosgo>
Allow ptrace to set dabr in the thread structure for both 32 and 64 bits,
though only 64 bits actually uses that field, it's actually defined in both.
