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)
