+ * 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 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

- * 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"...)
- *
- * The "user64" versions of the user access functions are versions that 
- * allow access of 64-bit data. The "get_user" functions do not 
- * properly handle 64-bit data because the value gets down cast to a long. 
- * The "put_user" functions already handle 64-bit data properly but we add

- * 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

+/*      Random Early Detection (RED) algorithm.
+        =======================================
+
+        Source: Sally Floyd and Van Jacobson, "Random Early Detection Gateways
+        for Congestion Avoidance", 1993, IEEE/ACM Transactions on Networking.
+
+        This file codes a "divisionless" version of RED algorithm
+        as written down in Fig.17 of the paper.
+
+        Short description.
+        ------------------
+
+        When a new packet arrives we calculate the average queue length:
+
+        avg = (1-W)*avg + W*current_queue_len,
+
+        W is the filter time constant (chosen as 2^(-Wlog)), it controls
+        the inertia of the algorithm. To allow larger bursts, W should be
+        decreased.
+
+        if (avg > th_max) -> packet marked (dropped).
+        if (avg < th_min) -> packet passes.
+        if (th_min < avg < th_max) we calculate probability:
+
+        Pb = max_P * (avg - th_min)/(th_max-th_min)
+
+        and mark (drop) packet with this probability.
+        Pb changes from 0 (at avg==th_min) to max_P (avg==th_max).
+        max_P should be small (not 1), usually 0.01..0.02 is good value.
+
+        max_P is chosen as a number, so that max_P/(th_max-th_min)
+        is a negative power of two in order arithmetics to contain
+        only shifts.
+
+
+        Parameters, settable by user:
+        -----------------------------
+
+        qth_min         - bytes (should be < qth_max/2)
+        qth_max         - bytes (should be at least 2*qth_min and less limit)
+        Wlog            - bits (<32) log(1/W).
+        Plog            - bits (<32)
+
+        Plog is related to max_P by formula:
+
+        max_P = (qth_max-qth_min)/2^Plog;
+
+        F.e. if qth_max=128K and qth_min=32K, then Plog=22
+        corresponds to max_P=0.02
+
+        Scell_log
+        Stab
+
+        Lookup table for log((1-W)^(t/t_ave).
+
+
+        NOTES:
+
+        Upper bound on W.
+        -----------------
+
+        If you want to allow bursts of L packets of size S,
+        you should choose W:
+
+        L + 1 - th_min/S < (1-(1-W)^L)/W
+
+        th_min/S = 32         th_min/S = 4
+
+        log(W)  L
+        -1      33
+        -2      35
+        -3      39
+        -4      46
+        -5      57
