+Subject: [PATCH] x86: Fix slight bug in `shared_per_thread` cache size
+ calculation.

+    commit af992e7abdc9049714da76cae1e5e18bc4838fb8

+
+        x86: Increase `non_temporal_threshold` to roughly `sizeof_L3 / 4`
+```
+
+Split `shared` (cumulative cache size) from `shared_per_thread` (cache
+size per socket), the `shared_per_thread` *can* be slightly off from
+the previous calculation.
+
+Previously we added `core` even if `threads_l2` was invalid, and only
+used `threads_l2` to divide `core` if it was present. The changed
+version only included `core` if `threads_l2` was valid.
+
+This change restores the old behavior if `threads_l2` is invalid by
+adding the entire value of `core`.
