/*
* 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.
