[patch 4/8] lock validator: early_init_irq_lock_type / console_init

[patch 4/8] lock validator: early_init_irq_lock_type / console_init

[Heiko Carstens]

From: Heiko Carstens <heiko.carstens@de.ibm.com>

Two changes:
 - let the kernel compile for architectures that support TRACE_IRQ_FLAGS but
   don't support GENERIC_HARDIRQS.
 - s390's console_init must enable interrupts, but early_boot_irqs_on() gets
   called later. To avoid problems move console_init() after local_irq_enable().
   Hope this works on all architectures?!
