No, not yet. My goal was to send soon a new RFC version of the patches.
In case you want to have a look, here is what I have for now:

 https://github.com/MISL-EBU-System-SW/mainline-public/commits/irqchip-improvements

Or the irqchip-improvements branch at
git at github.com:MISL-EBU-System-SW/mainline-public.git.

This is a heavily work-in-progress branch. Compared to the previous
version, the most significant changes are:

 * Integration of your GIC/VIC patches.

 * Usage of a linker script trick to accumulate the available irqchip
   drivers in order to avoid the global list in irqchip.{c,h} which
   would otherwise become a conflict nightmare.

 * More VIC cleanup patches so that vic_of_init() doesn't need to be
   exposed anymore.

 * Implementation of Arnd's idea of set_handle_irq() in the core ARM
   code.

Remains to be done:

 * Testing.

 * Validate that the linker script solution is acceptable.

 * Integrate Linus Walleij patches moving the FPGA irq controller code
   to drivers/irqchip/.

 * Solve Russell's comment about the header file location.

I'm hoping to make some progress on this either tomorrow or the day
after, but I think it's mostly 3.9 material at this point as we have
quite a few remaining problems to solve (the header file location for
gic and vic being the most important ones I'd say).

Best regards,

Thomas
