Subject: [RFT PATCH 1/9] sh/PCI: Remove __init optimisations from IRQ mapping functions/data
From: Matthew Minter <matt@...arand.com>
Currently the many IRQ mapping functions and data structures use
the __init and __initdata optimisations. These result in the
relevant functions being innacessable after boot time.
However for deferred IRQ assignment it is important to have
access to these functions at PCI device enable time.
Therefore the optimisation is removed from the relevant data
structures and functions to prepare for deferred IRQ assignment.
