If this ascii art is correct, memmove should be used instead of
memcpy.  Also, if initial order is kernel, string table, symbol table
and a gap between kernel and string table is smaller than symbol
table, copying it may overwrite the string table.

Is there any guarantee that the gap is large enough?
