From 8531a35e5e275b17c57c39b7911bc2b37025f28c Mon Sep 17 00:00:00 2001 From: "Kevin D. Kissell" Date: Tue, 9 Sep 2008 21:48:52 +0200 Subject: [MIPS] SMTC: Fix SMTC dyntick support. Rework of SMTC support to make it work with the new clock event system, allowing "tickless" operation, and to make it compatible with the use of the "wait_irqoff" idle loop. The new clocking scheme means that the previously optional IPI instant replay mechanism is now required, and has been made more robust. Signed-off-by: Kevin D.
