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!

+menu "Kernel hacking"
+
+source "lib/Kconfig.debug"
+
+# RMK wants arm kernels compiled with frame pointers so hardwire this to y.
+# If you know what you are doing and are willing to live without stack
+# traces, you can get a slightly smaller kernel by setting this option to
+# n, but then RMK will have to kill you ;).
+config FRAME_POINTER
+ bool
+ default y
+ help
+ If you say N here, the resulting kernel will be slightly smaller and
+ faster. However, when a problem occurs with the kernel, the
+ information that is reported is severely limited. Most people
+ should say Y here.
+
+config DEBUG_USER
+ bool "Verbose user fault messages"
+ help
+ When a user program crashes due to an exception, the kernel can
+ print a brief message explaining what the problem was. This is
+ sometimes helpful for debugging but serves no purpose on a
+ production system. Most people should say N here.
+
+config DEBUG_WAITQ
+ bool "Wait queue debugging"
+ depends on DEBUG_KERNEL
+
+config DEBUG_ERRORS
+ bool "Verbose kernel error messages"
+ depends on DEBUG_KERNEL
+ help
+ This option controls verbose debugging information which can be
+ printed when the kernel detects an internal error. This debugging
+ information is useful to kernel hackers when tracking down problems,
+ but mostly meaningless to other people. It's safe to say Y unless
+ you are concerned with the code size or don't want to see these
+ messages.
+
+# These options are only for real kernel hackers who want to get their hands dirty.
+config DEBUG_LL
+ bool "Kernel low-level debugging functions"
+ depends on DEBUG_KERNEL
+ help
+ Say Y here to include definitions of printascii, printchar, printhex
+ in the kernel. This is helpful if you are debugging code that
+ executes before the console is initialized.
