Linux-2.6.12-rc2v2.6.12-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!

+config EDD
+ tristate "BIOS Enhanced Disk Drive calls determine boot disk (EXPERIMENTAL)"
+ depends on EXPERIMENTAL
+ depends on !IA64
+ help
+ Say Y or M here if you want to enable BIOS Enhanced Disk Drive
+ Services real mode BIOS calls to determine which disk
+ BIOS tries boot from. This information is then exported via sysfs.
+
+ This option is experimental and is known to fail to boot on some
+ obscure configurations. Most disk controller BIOS vendors do
+ not yet implement this feature.
+
+config EFI_VARS
+ tristate "EFI Variable Support via sysfs"
+ depends on EFI
+ default n
+ help
+ If you say Y here, you are able to get EFI (Extensible Firmware
+ Interface) variable information via sysfs. You may read,
+ write, create, and destroy EFI variables through this interface.
+
+ Note that using this driver in concert with efibootmgr requires
+ at least test release version 0.5.0-test3 or later, which is
+ available from Matt Domsch's website located at:
+ <http://linux.dell.com/efibootmgr/testing/efibootmgr-0.5.0-test3.tar.gz>
+
+ Subsequent efibootmgr releases may be found at:
+ <http://linux.dell.com/efibootmgr>
+
+config EFI_PCDP
+ bool "Console device selection via EFI PCDP or HCDP table"
+ depends on ACPI && EFI && IA64
+ default y if IA64
+ help
+ If your firmware supplies the PCDP table, and you want to
+ automatically use the primary console device it describes
+ as the Linux console, say Y here.
+
+ If your firmware supplies the HCDP table, and you want to
+ use the first serial port it describes as the Linux console,
+ say Y here. If your EFI ConOut path contains only a UART
+ device, it will become the console automatically. Otherwise,
+ you must specify the "console=hcdp" kernel boot argument.
+
+ Neither the PCDP nor the HCDP affects naming of serial devices,
+ so a serial console may be /dev/ttyS0, /dev/ttyS1, etc, depending
+ on how the driver discovers devices.
+
+ You must also enable the appropriate drivers (serial, VGA, etc.)
