 * The description below was taken in large parts from the powerpc
 * bitops header file:
 * Within a word, bits are numbered LSB first.  Lot's of places make
 * this assumption by directly testing bits with (val & (1<<nr)).
 * This can cause confusion for large (> 1 word) bitmaps on a
 * big-endian system because, unlike little endian, the number of each
 * bit depends on the word size.
 *
 * The bitop functions are defined to work on unsigned longs, so the bits
 * end up numbered:
 *   |63..............0|127............64|191...........128|255...........192|
 *
 * We also have special functions which work with an MSB0 encoding.
 * The bits are numbered:
 *   |0..............63|64............127|128...........191|192...........255|
 *
 * The main difference is that bit 0-63 in the bit number field needs to be
 * reversed compared to the LSB0 encoded bit fields. This can be achieved by
 * XOR with 0x3f.
