/*
 * Solaris is somewhat picky about how many heads and sectors per track you
 * have defined in mode pages 3 and 4.  These values seem to cause Solaris
 * to get the capacity more or less right when you run the format tool.
 * They still have problems when dealing with devices larger than 1TB,
 * but there isn't anything we can do about that.
 *
 * For smaller LUN sizes, this ends up causing the number of cylinders to
 * work out to 0.  Solaris actually recognizes that and comes up with its
 * own bogus geometry to fit the actual capacity of the drive.  They really
 * should just give up on geometry and stick to the read capacity
 * information alone for modern disk drives.
 *
 * One thing worth mentioning about Solaris' mkfs command is that it
 * doesn't like sectors per track values larger than 256.  512 seems to
 * work okay for format, but causes problems when you try to make a
 * filesystem.
 *
 * Another caveat about these values:  the product of these two values
 * really should be a power of 2.  This is because of the simplistic
 * shift-based calculation that we have to use on the i386 platform to
 * calculate the number of cylinders here.  (If you use a divide, you end
 * up calling __udivdi3(), which is a hardware FP call on the PC.  On the
 * XScale, it is done in software, so you can do that from inside the
 * kernel.)
 *
 * So for the current values (256 S/T, 128 H), we get 32768, which works
 * very nicely for calculating cylinders.
 *
 * If you want to change these values so that their product is no longer a
 * power of 2, re-visit the calculation in ctl_init_page_index().  You may
 * need to make it a bit more complicated to get the number of cylinders
 * right.
