Add tile support for the EDAC driver, which provides unified system error (memory, PCI, etc.) reporting. For now, the TILEPro port reports memory correctable error (CE) only. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

The current implementations of __ndelay and __udelay call a hypervisor service to delay, but the hypervisor service isn't actually implemented very well, and the consensus is that Linux should handle figuring this out natively and not use a hypervisor service. By converting nanoseconds to cycles, and then spinning until the cycle counter reaches the desired cycle, we get several benefits: first, we are sensitive to the actual clock speed; second, we use less power by issuing a slow SPR read once every six cycles while we delay; and third, we properly handle the case of an interrupt by exiting at the target time rather than after some number of cycles.

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. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

This change rolls up random cleanups not representing any actual bugs. - Remove a stale CONFIG_ value from the default tile_defconfig - Remove unused tns_atomic_xxx() family of methods from <asm/atomic.h> - Optimize get_order() using Tile's "clz" instruction - Fix a bad hypervisor upcall name (not currently used in Linux anyway) - Use __copy_in_user_inatomic() name for consistency, and export it - Export some additional hypervisor driver I/O upcalls and some homecache calls - Remove the obfuscating MEMCPY_TEST_WH64 support code - Other stray comment cleanups, #if 0 removal, etc. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com>

None of these changes fix any actual bugs, but are just various cleanups that fell out along the way. In particular, some unused #defines and includes are removed, PREFETCH_STRIDE is added (the default is right for our shipping chips, but wrong for our next generation), our tile-specific prefetching code is removed so the (identical) generic prefetching code can be used instead, a comment is fixed to be proper GPL and not just a "paste GPL here" token, a "//" comment is converted to "/* */", etc. Signed-off-by: NChris Metcalf <cmetcalf@tilera.com> Acked-by: NArnd Bergmann <arnd@arndb.de>

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/.

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/.
