Geert Uytterhoeven 193dc44179 of: Fix truncation of memory sizes on 32-bit platforms ... [ Upstream commit 2892d8a00d ] Variable "size" has type "phys_addr_t", which can be either 32-bit or 64-bit on 32-bit systems, while "unsigned long" is always 32-bit on 32-bit systems. Hence the cast in (unsigned long)size / SZ_1M may truncate a 64-bit size to 32-bit, as casts have a higher operator precedence than divisions. Fix this by inverting the order of the cast and division, which should be safe for memory blocks smaller than 4 PiB. Note that the division is actually a shift, as SZ_1M is a power-of-two constant, hence there is no need to use div_u64(). While at it, use "%lu" to format "unsigned long".
