[PATCH] [2.6.22] powerpc: uninline and export virq_to_hw()

[Olof Johansson]

Uninline virq_to_hw and export it so modules can use it. The alternative
would be to export the irq_map array instead, but it's an infrequently
called function, and keeping the array unexported seems considerably
cleaner.
