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)
