Marcel Moolenaar cc7a041c2b Disable interrupts when calling into SAL for PCI configuration ... cycles. This serves 2 purposes: 1. It prevents preemption and CPU migration while running SAL code. 2. It reduces the chance of stack overflows: we're supposed to enter SAL with at least 16KB of either memory- or register stack space, which we can't do without switching to a different stack.		2010-03-22 03:06:11 +00:00
