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 EARLY_PRINTK
+        bool "Early printk" if EMBEDDED && DEBUG_KERNEL
+        default y
+        help
+          Write kernel log output directly into the VGA buffer or to a serial
+          port.
+
+          This is useful for kernel debugging when your machine crashes very
+          early before the console code is initialized. For normal operation
+          it is not recommended because it looks ugly and doesn't cooperate
+          with klogd/syslogd or the X server. You should normally N here,
+          unless you want to debug such a crash.
+
+config DEBUG_STACKOVERFLOW
+        bool "Check for stack overflows"
+        depends on DEBUG_KERNEL
+
+config KPROBES
+        bool "Kprobes"
+        depends on DEBUG_KERNEL
+        help
+          Kprobes allows you to trap at almost any kernel address and
+          execute a callback function.  register_kprobe() establishes
+          a probepoint and specifies the callback.  Kprobes is useful
+          for kernel debugging, non-intrusive instrumentation and testing.
+          If in doubt, say "N".
+
+config DEBUG_STACK_USAGE
+        bool "Stack utilization instrumentation"
+        depends on DEBUG_KERNEL
+        help
+          Enables the display of the minimum amount of free stack which each
+          task has ever had available in the sysrq-T and sysrq-P debug output.
+
+          This option will slow down process creation somewhat.

+config DEBUG_PAGEALLOC
+        bool "Page alloc debugging"
+        depends on DEBUG_KERNEL && !SOFTWARE_SUSPEND
+        help
+          Unmap pages from the kernel linear mapping after free_pages().
+          This results in a large slowdown, but helps to find certain types
+          of memory corruptions.
+
+config 4KSTACKS
+        bool "Use 4Kb for kernel stacks instead of 8Kb"
+        depends on DEBUG_KERNEL
+        help
+          If you say Y here the kernel will use a 4Kb stacksize for the
+          kernel stack attached to each process/thread. This facilitates
+          running more threads on a system and also reduces the pressure
+          on the VM subsystem for higher order allocations. This option
+          will also use IRQ stacks to compensate for the reduced stackspace.
