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!

+ * XFS arguments structure, constructed from the arguments we
+ * are passed via the mount system call.
+ *
+ * NOTE: The mount system call is handled differently between
+ * Linux and IRIX.  In IRIX we worked work with a binary data
+ * structure coming in across the syscall interface from user
+ * space (the mount userspace knows about each filesystem type
+ * and the set of valid options for it, and converts the users
+ * argument string into a binary structure _before_ making the
+ * system call), and the ABI issues that this implies.
+ *
+ * In Linux, we are passed a comma separated set of options;
+ * ie. a NULL terminated string of characters.  Userspace mount
+ * code does not have any knowledge of mount options expected by
+ * each filesystem type and so each filesystem parses its mount
+ * options in kernel space.
+ *
+ * For the Linux port, we kept this structure pretty much intact
+ * and use it internally (because the existing code groks it).
