 236  * for global_data. Then it calls arch_setup_gd() which sets gd to point to

 242  * [1] Strictly speaking it would be possible to implement this function
 243  * in C on many archs such that it does not require a stack. However this
 244  * does not seem hugely important as only 64 byte are wasted. The 64 bytes
 245  * are used to handle the calling standard which generally requires pushing
 246  * addresses or registers onto the stack. We should be able to get away with
 247  * less if this becomes important.
