Chris Metcalf c78095bd8c arch/tile: Split the icache flush code off to a generic <arch> header.
This code is used in other places in our system than in Linux, so
to share it we now implement it as an inline function in our low-level
<arch> headers, and instantiate it in one file in Linux's arch/tile/lib.
The file is now cacheflush.c and is C code rather than the strangely-named
and assembler-implemented __invalidate_icache.S.

Chris Metcalf 2db0982781 arch/tile: Fix bug in support for atomic64_xx() ops.
This wasn't properly tested until the perf-event subsystem started
to get brought up under the tile architecture.

The bug caused bogus atomic64_cmpxchg() values to be returned,
among other things.

Chris Metcalf 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/.
