Raw Normal View History

Linux-2.6.12-rc2 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!

PCI Hotplug: cpqphp: clean up accesses to pcibios_get_irq_routing_table() Instead of making multiple calls to pcibios_get_irq_routing_table, let's just do it once and save the answer. The reason we were making multiple calls is because we liked to calculate its length and perform some loop over it. Instead of open-coding the length calculation every time, provide it in an inline helper function. Finally, since pci_print_IRQ_route() is used only for debug, let's only do it when cpqhp_debug is set.

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!

PCI Hotplug: cpqphp: clean up accesses to pcibios_get_irq_routing_table() Instead of making multiple calls to pcibios_get_irq_routing_table, let's just do it once and save the answer. The reason we were making multiple calls is because we liked to calculate its length and perform some loop over it. Instead of open-coding the length calculation every time, provide it in an inline helper function. Finally, since pci_print_IRQ_route() is used only for debug, let's only do it when cpqhp_debug is set.
