arch/tile: Various cleanups.
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: Chris Metcalf <cmetcalf@tilera.com>
