parisc: Show DIMM slot number which holds broken memory module (c46bafc4) · Commits · 戴 / test

The Page Deallocation Table (PDT) holds the physical addresses of all broken memory addresses. With the physical address we now are able to show which DIMM slot (e.g. 1a, 3c) actually holds the broken memory module so that users are able to replace it. Signed-off-by:
