This is because of the simplistic 209 * shift-based calculation that we have to use on the i386 platform to 210 * calculate the number of cylinders here. (If you use a divide, you end 211 * up calling __udivdi3(), which is a hardware FP call on the PC. On the 212 * XScale, it is done in software, so you can do that from inside the 213 * kernel.) 214 * 215 * So for the current values (256 S/T, 128 H), we get 32768, which works 216 * very nicely for calculating cylinders. 217 * 218 * If you want to change these values so that their product is no longer a 219 * power of 2, re-visit the calculation in ctl_init_page_index().
