[Ingo Molnar - Tue, May 12, 2009 at 06:46:17PM +0200] | | got this on a testbox: | | [ 0.113333] WARNING: at arch/x86/kernel/apic/apic.c:253 warn_slowpath_null+0x28/0x50() | | Ingo |
It's expected (unfortunately). If we have SMP compiled kernel we still rely on apic_read heavily. Since for fake'ed apic we just return 0 for any reading I suspect we could just drop WARN_ON_ONCE for native_apic_read_dummy. Yinghai?
(well, actually we should clean up callees but it would require some effort)
