    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.
