[patch, -rc5-mm3] lock validator: sparc64, sparc, m68k, alpha, cris, irqtrace build fix

[Ingo Molnar]

Subject: lock validator: sparc64, sparc, m68k, alpha, cris, irqtrace build fix
From: Ingo Molnar <mingo@elte.hu>

early_init_irq_lock_type() should only be provided by an architecture
if it offers CONFIG_TRACE_IRQFLAGS.

this makes sparc64 (and probably the other non-genirq arches) build.
