FL and SL page tables are very similar, and I presume we are not using
all the flag bits in FL paging structures for DMA mapping. Are there
enough relevant differences to warrant a new set of helper functions
for FL? Or we can merge into one.
I evaluated your suggestion these days. It turned out that your
suggestion make code simpler and easier for maintainence. Thank you for
the comment and I will send out a new version for review soon.
Best regards,
