60ef690018b262 Yury Norov 2017-09-08 551 * BITMAP_FROM_U64() - Represent u64 value in the format suitable for bitmap.
404376af788a76 Randy Dunlap 2017-09-17 552 * @n: u64 value
60ef690018b262 Yury Norov 2017-09-08 553 *
60ef690018b262 Yury Norov 2017-09-08 554 * Linux bitmaps are internally arrays of unsigned longs, i.e. 32-bit
60ef690018b262 Yury Norov 2017-09-08 555 * integers in 32-bit environment, and 64-bit integers in 64-bit one.
60ef690018b262 Yury Norov 2017-09-08 556 *
60ef690018b262 Yury Norov 2017-09-08 557 * There are four combinations of endianness and length of the word in linux
60ef690018b262 Yury Norov 2017-09-08 558 * ABIs: LE64, BE64, LE32 and BE32.
60ef690018b262 Yury Norov 2017-09-08 559 *
60ef690018b262 Yury Norov 2017-09-08 560 * On 64-bit kernels 64-bit LE and BE numbers are naturally ordered in
60ef690018b262 Yury Norov 2017-09-08 561 * bitmaps and therefore don't require any special handling.
60ef690018b262 Yury Norov 2017-09-08 562 *
60ef690018b262 Yury Norov 2017-09-08 563 * On 32-bit kernels 32-bit LE ABI orders lo word of 64-bit number in memory
60ef690018b262 Yury Norov 2017-09-08 564 * prior to hi, and 32-bit BE orders hi word prior to lo. The bitmap on the
60ef690018b262 Yury Norov 2017-09-08 565 * other hand is represented as an array of 32-bit words and the position of
60ef690018b262 Yury Norov 2017-09-08 566 * bit N may therefore be calculated as: word #(N/32) and bit #(N%32) in that
60ef690018b262 Yury Norov 2017-09-08 567 * word. For example, bit #42 is located at 10th position of 2nd word.
60ef690018b262 Yury Norov 2017-09-08 568 * It matches 32-bit LE ABI, and we can simply let the compiler store 64-bit
60ef690018b262 Yury Norov 2017-09-08 569 * values in memory as it usually does. But for BE we need to swap hi and lo
60ef690018b262 Yury Norov 2017-09-08 570 * words manually.
60ef690018b262 Yury Norov 2017-09-08 571 *
60ef690018b262 Yury Norov 2017-09-08 572 * With all that, the macro BITMAP_FROM_U64() does explicit reordering of hi and
60ef690018b262 Yury Norov 2017-09-08 573 * lo parts of u64. For LE32 it does nothing, and for BE environment it swaps
60ef690018b262 Yury Norov 2017-09-08 574 * hi and lo words, as is expected by bitmap.
