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!

+config PCI_MSI
+ bool "Message Signaled Interrupts (MSI and MSI-X)"
+ depends on PCI
+ depends on (X86_LOCAL_APIC && X86_IO_APIC) || IA64
+ help
+ This allows device drivers to enable MSI (Message Signaled
+ Interrupts). Message Signaled Interrupts enable a device to
+ generate an interrupt using an inbound Memory Write on its
+ PCI bus instead of asserting a device IRQ pin.
+
+ If you don't know what to do here, say N.
+
+config PCI_LEGACY_PROC
+ bool "Legacy /proc/pci interface"
+ depends on PCI
+ ---help---
+ This feature enables a procfs file -- /proc/pci -- that provides a
+ summary of PCI devices in the system.
+
+ This feature has been deprecated as of v2.5.53, in favor of using the
+ tool lspci(8). This feature may be removed at a future date.
+
+ lspci can provide the same data, as well as much more. lspci is a part of
+ the pci-utils package, which should be installed by your distribution.
+ See <file:Documentation/Changes> for information on where to get the latest
+ version.
+
+ When in doubt, say N.
+
+config PCI_NAMES
+ bool "PCI device name database"
+ depends on PCI
+ ---help---
+ By default, the kernel contains a database of all known PCI device
+ names to make the information in /proc/pci, /proc/ioports and
+ similar files comprehensible to the user.
+
+ This database increases size of the kernel image by about 80KB. This
+ memory is freed after the system boots up if CONFIG_HOTPLUG is not set.
+
+ Anyway, if you are building an installation floppy or kernel for an
+ embedded system where kernel image size really matters, you can disable
+ this feature and you'll get device ID numbers instead of names.
+
+ When in doubt, say Y.
+
+config PCI_DEBUG
+ bool "PCI Debugging"
+ depends on PCI && DEBUG_KERNEL
+ help
+ Say Y here if you want the PCI core to produce a bunch of debug
+ messages to the system log. Select this if you are having a
+ problem with PCI support and want to see more of what is going on.
+
+ When in doubt, say N.
