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!

+ * Function: v4t_early_abort
+ *
+ * Params  : r2 = address of aborted instruction
+ *         : r3 = saved SPSR
+ *
+ * Returns : r0 = address of abort
+ *	   : r1 = FSR, bit 11 = write
+ *	   : r2-r8 = corrupted
+ *	   : r9 = preserved
+ *	   : sp = pointer to registers
+ *
+ * Purpose : obtain information about current aborted instruction.
+ * Note: we read user space.  This means we might cause a data
+ * abort here if the I-TLB and D-TLB aren't seeing the same
+ * picture.  Unfortunately, this does happen.  We live with it.
