Changeset 9827:ec5271f10386 --------------------------- alpha: Check interrupts before quiesce This patch adds a check to the quiesce operation to ensure that the CPU does not suspend itself when there are unmasked interrupts pending. Without this patch there are corner cases when the CPU gets an interrupt before the quiesce is executed and then never wakes up again.
All regressions pass.

Any input on this one? The DRAM write merge patch (http://reviews.gem5.org/r/1962/) requires this to go in first to not have regressions stalling.
