1/*
2 * PowerPC64 atomic bit operations.
3 * Dave Engebretsen, Todd Inglett, Don Reed, Pat McCarthy, Peter Bergner,
4 * Anton Blanchard
5 *
6 * Originally taken from the 32b PPC code. Modified to use 64b values for
7 * the various counters & memory references.
8 *
9 * Bitops are odd when viewed on big-endian systems. They were designed
10 * on little endian so the size of the bitset doesn't matter (low order bytes
11 * come first) as long as the bit in question is valid.
12 *
13 * Bits are "tested" often using the C expression (val & (1<<nr)) so we do
14 * our best to stay compatible with that. The assumption is that val will
15 * be unsigned long for such tests. As such, we assume the bits are stored
16 * as an array of unsigned long (the usual case is a single unsigned long,
17 * of course). Here's an example bitset with bit numbering:
18 *
19 * |63..........0|127........64|195.......128|255.......196|
20 *
21 * This leads to a problem. If an int, short or char is passed as a bitset
22 * it will be a bad memory reference since we want to store in chunks
23 * of unsigned long (64 bits here) size.
24 *
25 * There are a few little-endian macros used mostly for filesystem bitmaps,
26 * these work on similar bit arrays layouts, but byte-oriented:
27 *
28 * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
29 *
30 * The main difference is that bit 3-5 in the bit number field needs to be
31 * reversed compared to the big-endian bit fields. This can be achieved
32 * by XOR with 0b111000 (0x38).
33 *

35 * modify it under the terms of the GNU General Public License
