[PATCH] setup_boot_APIC_clock() irq-enable fix
latest -git triggers an irqtrace/lockdep warning of a leaked irqs-off condition: BUG: at kernel/fork.c:1033 copy_process() after some debugging it turns out that commit ca1b940c accidentally left interrupts disabled - which trickled down all the way to the first time we fork a kernel thread and triggered the warning. the fix is to re-enable interrupts in the 'else' branch of setup_boot_APIC_clock()'s pmtimers calibration path.
