Hi
without this patch, addresses are bad calculated for
r4k in 64bits mode. Notice that the corresponding variables for
instruction and data caches already were unsigned long.
a = addr & ~(sc_lsize - 1);
end = (addr + size - 1) & ~(sc_lsize - 1);
Problem is that in this kind of expression, it uses 32 bits to
calculate ~(sc_lsize -1). I don't know if this is really a compiler
or kernel bug.
Later, Juan.
