+/*
+ * PowerPC atomic bit operations.
+ *
+ * Merged version by David Gibson <david@gibson.dropbear.id.au>.
+ * Based on ppc64 versions by: Dave Engebretsen, Todd Inglett, Don
+ * Reed, Pat McCarthy, Peter Bergner, Anton Blanchard. They
+ * originally took it from the ppc32 code.
+ *
+ * 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 for a
+ * ppc64 system the bits end up numbered:
+ * |63..............0|127............64|191...........128|255...........196|
+ * and on ppc32:
+ * |31.....0|63....31|95....64|127...96|159..128|191..160|223..192|255..224|
+ *
+ * There are a few little-endian macros used mostly for filesystem
+ * bitmaps, these work on similar bit arrays layouts, but
+ * byte-oriented:
+ * |7...0|15...8|23...16|31...24|39...32|47...40|55...48|63...56|
+ *
+ * The main difference is that bit 3-5 (64b) or 3-4 (32b) in the bit
+ * number field needs to be reversed compared to the big-endian bit
+ * fields. This can be achieved by XOR with 0x38 (64b) or 0x18 (32b).
+ *
+ * This program is free software; you can redistribute it and/or
+ * modify it under the terms of the GNU General Public License
+ * as published by the Free Software Foundation; either version

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

- * This gets kind of ugly. We want to return _two_ values in "get_user()"
- * and yet we don't want to do any pointers, because that is too much
- * of a performance impact. Thus we have a few rather ugly macros here,
- * and hide all the ugliness from the user.
- *
- * The "__xxx" versions of the user access functions are versions that
- * do not verify the address space, that must have been done previously
- * with a separate "access_ok()" call (this is used when we do multiple
- * accesses to the same area of user memory).
- *
- * As we use the same address space for kernel and user data on the
- * PowerPC, we can just do these as direct assignments. (Of course, the
- * exception handling means that it's no longer "just"...)
