Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

128 A dev_link_t structure has fields for most things that are needed

131 'priv' pointer in a dev_link_t structure can be used to point to
132 a device-specific private data structure, like this.
133
134 A driver needs to provide a dev_node_t structure for each device
135 on a card. In some cases, there is only one device per card (for
136 example, ethernet cards, modems). In other cases, there may be
137 many actual or logical devices (SCSI adapters, memory cards with
138 multiple partitions). The dev_node_t structures need to be kept
139 in a linked list starting at the 'dev' field of a dev_link_t
140 structure. We allocate them in the card's private data structure,
141 because they generally shouldn't be allocated dynamically.
142
143 In this case, we also provide a flag to indicate if a device is
144 "stopped" due to a power management event, or card ejection. The
145 device IO routines can use a flag like this to throttle IO to a
