# HG changeset patch # User kaf24@xxxxxxxxxxxxxxxxxxxx # Node ID 4c8311699685c0925fbd4415812a23ba4bffc66b # Parent c783f340bef82223eb5fcd88093fd919f41790b6 Make event_pending() architecture-specific. PowerPC needs this because the domain can directly modify the hardware's "interrupts enabled" bit, and we don't want to patch Linux to replace all those accesses to use evtchn_upcall_mask instead.
