Subject: [PATCH 5/6] ARM: Don't set TLB ops broadcasting on UP ARMv7
Date: Mon, 30 Aug 2010 14:03:28 -0700 [thread overview]
Message-ID: <mailman.224.1283444542.27306.linux-arm-kernel@lists.infradead.org> (raw)
Don't set TLB ops broadcasting on UP ARMv7. Looks like these bits
are also different on A8 and A9.
