From 1267a8df209c7453d65acbdd56e3588954bf890b Mon Sep 17 00:00:00 2001 From: David Daney Date: Tue, 27 Jan 2009 09:53:21 -0800 Subject: Make irq_*_affinity depend on CONFIG_GENERIC_HARDIRQS too. In interrupt.h these functions are declared only if CONFIG_GENERIC_HARDIRQS is set. We should define them under identical conditions.

All of these happen before core_initcall. Moving the initialization to early_irq_init ensures that it is initialized before it is used.
