+ * of three different types:
+ *
+ * Select field: this expresses the constraint that some set of bits
+ * in MMCR* needs to be set to a specific value for this event. For a
+ * select field, the mask contains 1s in every bit of the field, and
+ * the value contains a unique value for each possible setting of the
+ * MMCR* bits. The constraint checking code will ensure that two events
+ * that set the same field in their masks have the same value in their
+ * value dwords.
+ *
+ * Add field: this expresses the constraint that there can be at most
+ * N events in a particular class. A field of k bits can be used for
+ * N <= 2^(k-1) - 1. The mask has the most significant bit of the field
+ * set (and the other bits 0), and the value has only the least significant
+ * bit of the field set. In addition, the 'add_fields' and 'test_adder'
+ * in the struct power_pmu for this processor come into play. The
+ * add_fields value contains 1 in the LSB of the field, and the
+ * test_adder contains 2^(k-1) - 1 - N in the field.
+ *
+ * NAND field: this expresses the constraint that you may not have events
+ * in all of a set of classes. (For example, on PPC970, you can't select
+ * events from the FPU, ISU and IDU simultaneously, although any two are
+ * possible.) For N classes, the field is N+1 bits wide, and each class
+ * is assigned one bit from the least-significant N bits. The mask has
+ * only the most-significant bit set, and the value has only the bit
+ * for the event's class set. The test_adder has the least significant
+ * bit set in the field.
+ *
+ * If an event is not subject to the constraint expressed by a particular
+ * field, then it will have 0 in both the mask and value for that field.

- * Modified for MIPS by Jun Sun, jsun@mvista.com
- *
- * . Simplify the interface between pci_auto and the rest: a single function.
- * . Assign resources from low address to upper address.
- * . change most int to u32.
- *
- * Further modified to include it as mips generic code, ppopov@mvista.com.
- *
- * 2001-10-26 Bradley D. LaRonde <brad@ltc.com>
- * - Add a top_bus argument to the "early config" functions so that
- * they can set a fake parent bus pointer to convince the underlying
- * pci ops to use type 1 configuration for sub busses.
- * - Set bridge base and limit registers correctly.
- * - Align io and memory base properly before and after bridge setup.
- * - Don't fall through to pci_setup_bars for bridge.
- * - Reformat the debug output to look more like lspci's output.
- *
- * Cloned for SuperH by M. R. Brown, mrbrown@0xd6.org
- *
- * 2003-08-05 Paul Mundt <lethal@linux-sh.org>
- * - Don't update the BAR values on systems that already have valid addresses
- * and don't want these updated for whatever reason, by way of a new config
- * option check. However, we still read in the old BAR values so that they
- * can still be reported through the debug output.

- FIXME : What if usecs_per_tick is moving around too much, e.g. if an adjtime

- we have calibrated the scaling factor? This will result in either a jump at
- the end of a tick period, or a wrap backwards at the start of the next one,
- if the application is reading the time of day often enough. I think we
- ought to do better than this. For this reason, usecs_per_jiffy is left
- separated out in the calculation below. This allows some future hook into
- the adjtime-related stuff in kernel/timer.c to remove this hazard.
