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!

+ * All of the FPGA interrupt request inputs except for the touchscreen are

+ * interrupts are acknowledged as a side-effect of reading the interrupt
+ * status register from the FPGA.  The edge-sensitive interrupt inputs
+ * cause a problem with level interrupt requests, such as Ethernet.  The
+ * problem occurs when a level interrupt request is asserted while its
+ * interrupt input is masked in the FPGA, which results in a missed
+ * interrupt.
+ *
+ * In an attempt to workaround the problem with missed interrupts, the
+ * mask_ack routine for all of the FPGA interrupts has been changed from
+ * fpga_mask_ack_irq() to fpga_ack_irq() so that the specific FPGA interrupt
+ * being serviced is left unmasked.  We can do this because the FPGA cascade
+ * interrupt is installed with the SA_INTERRUPT flag, which leaves all
+ * interrupts masked at the CPU while an FPGA interrupt handler executes.
+ *
+ * Limited testing indicates that this workaround appears to be effective
+ * for the smc9194 Ethernet driver used on the Innovator.  It should work
+ * on other FPGA interrupts as well, but any drivers that explicitly mask
+ * interrupts at the interrupt controller via disable_irq/enable_irq
+ * could pose a problem.
