Currently the upper 16 bits of the GD flags are reserved for
architecture specific flags. But only x86 uses 2 bits of these 16 bits
and sprinkling those flags in multiple headers is confusing and does not
scale.

This patch now moves the x86 flags into the common header and removes
the comment about the reservation of the upper 16 bits.
