This completes the tile migration to the new naming scheme for
the architecture-specific irq management code.

a78c942df6 arch/tile: parameterize system PLs to support KVM port
While not a port to KVM (yet), this change modifies the kernel
to be able to build either at PL1 or at PL2 with a suitable
config switch.  Pushing up this change avoids handling branch
merge issues going forward with the KVM work.

d1ea13c6e2 genirq: Cleanup irq_chip->typename leftovers
3 years transition phase is enough. Cleanup the last users and remove
the cruft.

fb702b942b arch/tile: Enable more sophisticated IRQ model for 32-bit chips.
This model is based on the on-chip interrupt model used by the
TILE-Gx next-generation hardware, and interacts much more cleanly
with the Linux generic IRQ layer.

The change includes modifications to the Tilera hypervisor, which
are reflected in the hypervisor headers in arch/tile/include/arch/.

867e359b97 arch/tile: core support for Tilera 32-bit chips.
This change is the core kernel support for TILEPro and TILE64 chips.
No driver support (except the console driver) is included yet.

This includes the relevant Linux headers in asm/; the low-level
low-level "Tile architecture" headers in arch/, which are
shared with the hypervisor, etc., and are build-system agnostic;
and the relevant hypervisor headers in hv/.
