From a58786917ce23c2a26c3e099c3cdba32a35eeceb Mon Sep 17 00:00:00 2001 From: Bjorn Helgaas Date: Mon, 30 Jan 2006 16:32:31 -0700 Subject: [IA64] avoid broken SAL_CACHE_FLUSH implementations If SAL_CACHE_FLUSH drops interrupts, complain about it and fall back to using PAL_CACHE_FLUSH instead. This is to work around a defect in HP rx5670 firmware: when an interrupt occurs during SAL_CACHE_FLUSH, SAL drops the interrupt but leaves it marked "in-service", which leaves the interrupt (and others of equal or lower priority) masked.
