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!

+
+ If you say N here, the kernel will run on single and multiprocessor

+
+config PREEMPT
+ bool "Preemptible Kernel"
+ help
+ This option reduces the latency of the kernel when reacting to

+ be preempted even if it is in kernel mode executing a system call.
+ This allows applications to run more reliably even when the system is

+ IA-64 processors can execute IA-32 (X86) instructions. By

+ emulation support which makes it possible to transparently
+ run IA-32 Linux binaries on an IA-64 Linux system.

+ help
+ Selects whether support for the IA-64 performance monitor hardware
+ is included in the kernel. This makes some kernel data-structures a

+
+config IA64_PALINFO
+ tristate "/proc/pal support"
+ help
+ If you say Y here, you are able to get PAL (Processor Abstraction
+ Layer) information in /proc/pal. This contains useful information
+ about the processors in your systems, such as cache and TLB sizes
+ and the PAL firmware version in use.
+
+ To use this option, you have to ensure that the "/proc file system

+ "Power Management" means that parts of your computer are shut

+ being used. There are two competing standards for doing this: APM
+ and ACPI. If you want to use either one, say Y here and then also
+ to the requisite support below.

+ Battery Powered Linux mini-HOWTO, available from
+ <http://www.tldp.org/docs.html#howto>.
+
+ Note that, even if you say N here, Linux on the x86 architecture
+ will issue the hlt instruction if nothing is to be done, thereby
+ sending the processor to sleep and saving power.
