+Subject: [PATCH] x86: Avoid integer truncation with large cache sizes (bug
+ 32470)
+
+Some hypervisors report 1 TiB L3 cache size.  This results
+in some variables incorrectly getting zeroed, causing crashes
+in memcpy/memmove because invariants are violated.
+
+(cherry picked from commit 61c3450db96dce96ad2b24b4f0b548e6a46d68e5)
