This function should be called from the implementation files KSPCreate_XXX() to declare
which norms and preconditioner sides are supported. Users should not need to call this
function.
<P>
<A HREF="../KSP/KSP_NORM_NONE.html#KSP_NORM_NONE">KSP_NORM_NONE</A> is supported by default with all <A HREF="../KSP/KSP.html#KSP">KSP</A> methods and any <A HREF="../PC/PC.html#PC">PC</A> side. If a <A HREF="../KSP/KSP.html#KSP">KSP</A> explicitly does not support
<A HREF="../KSP/KSP_NORM_NONE.html#KSP_NORM_NONE">KSP_NORM_NONE</A>, it should set this by setting priority=0.
