The LPA2 extension implements 52-bit virtual addressing for 4k and 16k
translation granules, and for the former, this means an additional level
of translation is needed. This means we start counting at -1 instead of
0 when doing a walk, and so 'level' is now a signed quantity, and should
be typed as such. So turn it from uint32_t into int32_t.
