* Missing asm support

* 'unsigned __init128' data type as direct representation of
* 128 bit constants is not supported in the gcc compiler, as
* they get silently truncated.
*
* TODO: Please revisit this implementation when gcc compiler
* starts representing 128 bit constants directly like long
* and unsigned long etc. Subsequently drop the comment for
* GENMASK_U128() which would then start supporting asm code.
