PATCH 1/1 Specialix/IO8

Hi,

This patch converts all save_flags/restore_flags to the new spin_lick_irqsave/spin_unlock_irqrestore calls, as well as some other 2.6.X cleanups. This allows the "io8+" driver to become SMP safe.

The large size of this patch comes mostly from the added debug features.
