With 16KB pages and a kernel Image larger than 16MB, the current kaslr_early_init() logic for avoiding mappings across swapper table boundaries fails since increasing the offset by kimg_sz just moves the problem to the next boundary. This patch rounds the offset down to (1 << SWAPPER_TABLE_SHIFT) if the Image crosses a PMD_SIZE boundary.
