RE: [PATCH v2 UPDATE 3/3] ACPI/APEI/EINJ: Allow memory error injection to NVDIMM

[Luck, Tony]

-	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?
