77  * __BIT(n): Return a bitmask with bit n set, where the least
78  *           significant bit is bit 0.
79  *
80  * __BITS(m, n): Return a bitmask with bits m through n, inclusive,
81  *               set.  It does not matter whether m>n or m<=n.  The
82  *               least significant bit is bit 0.
83  *
84  * A "bitfield" is a span of consecutive bits defined by a bitmask,
85  * where 1s select the bits in the bitfield.  __SHIFTIN, __SHIFTOUT,
86  * and __SHIFTOUT_MASK help read and write bitfields from device
87  * registers.
88  *
89  * __SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
90  *                     defined by `mask', and return them.  No
91  *                     side-effects.
92  *
93  * __SHIFTOUT(v, mask): Extract and return the bitfield selected
94  *                      by `mask' from `v', right-shifting the
95  *                      bits so that the rightmost selected bit
96  *                      is at bit 0.  No side-effects.
97  *
98  * __SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
99  *                        the rightmost non-zero bit is at bit
100  *                        0.  This is useful for finding the
101  *                        greatest unsigned value that a bitfield
102  *                        can hold.  No side-effects.  Note that
103  *                        __SHIFTOUT_MASK(m) = __SHIFTOUT(m, m).
