From 4904033302c745342e3b3a611881cdee57fbe06a Mon Sep 17 00:00:00 2001 From: Ingo Molnar Date: Wed, 28 Jan 2009 12:43:18 +0100 Subject: x86: refactor ->enable_apic_mode() subarch methods Only ES7000 has a real ->enable_apic_mode() method, the other subarchitectures define it but keep it empty. So mark the vector as NULL, extend the generic code to handle NULL -setup_portio_remap() entries and remove all the empty handlers.
