Nope, it still gives me memory above 4GB. If I change goal to 0x0 it
works. One nit, shouldn't IS_LOW_AGES() be more like this:
#define IS_LOWPAGES(paddr, size) ((paddr+size-1) < 0x100000000UL)
Minor optimization not checking the start, but a 64MB swiotlb starting
at 4GB-64MB should be found as ok. Thanks,
Alex
