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!

+|       Takes the result and puts it in where the user expects it.
+|       Library functions return result in fp0. If fp0 is not the
+|       users destination register then fp0 is moved to the
+|       correct floating-point destination register.  fp0 and fp1
+|       are then restored to the original contents.
+|
+|       Input:  result in fp0,fp1
+|
+|               d2 & a0 should be kept unmodified
+|
+|       Output: moves the result to the true destination reg or mem
+|
+|       Modifies: destination floating point register
