- pfn = PFN_DOWN(param1 & param2); - if (!page_is_ram(pfn) || ((param2 & PAGE_MASK) != PAGE_MASK)) + base_addr = param1 & param2; + size = (~param2) + 1;
We expect the user will supply us with param2 in the form 0xffffffff[fec8]00000 with various numbers of leading 'f' and trailing '0' ... but I don't think we actually check that anywhere. But we have a bunch of places that assume it is OK, including this new one. It's time to fix that. Maybe even provide a default 0xfffffffffffff000 so I can save myself some typing? -Tony -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
