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!

+ * The table's mode will be honoured both for sys_sysctl(2) and

+ * null procname disables /proc mirroring at this node.
+ *
+ * sysctl(2) can automatically manage read and write requests through
+ * the sysctl table. The data and maxlen fields of the ctl_table
+ * struct enable minimal validation of the values being written to be
+ * performed, and the mode field allows minimal authentication.
+ *
+ * More sophisticated management can be enabled by the provision of a
+ * strategy routine with the table entry. This will be called before
+ * any automatic read or write of the data is performed.
+ *
+ * The strategy routine may return:
+ * <0: Error occurred (error is passed to user process)
+ * 0: OK - proceed with automatic read or write.
+ * >0: OK - read or write has been done by the strategy routine, so
+ * return immediately.
+ *
+ * There must be a proc_handler routine for any terminal nodes
+ * mirrored under /proc/sys (non-terminals are handled by a built-in
+ * directory handler). Several default handlers are available to
+ * cover common cases.
