* __BIT(n): Return a bitmask with bit n set, where the least
* significant bit is bit 0.
*
* __BITS(m, n): Return a bitmask with bits m through n, inclusive,
* set. It does not matter whether m>n or m<=n. The
* least significant bit is bit 0.
*
* A "bitfield" is a span of consecutive bits defined by a bitmask,
* where 1s select the bits in the bitfield. __SHIFTIN, __SHIFTOUT,
* and __SHIFTOUT_MASK help read and write bitfields from device
* registers.
*
* __SHIFTIN(v, mask): Left-shift bits `v' into the bitfield
* defined by `mask', and return them. No
* side-effects.
*
* __SHIFTOUT(v, mask): Extract and return the bitfield selected
* by `mask' from `v', right-shifting the
* bits so that the rightmost selected bit
* is at bit 0. No side-effects.
*
* __SHIFTOUT_MASK(mask): Right-shift the bits in `mask' so that
* the rightmost non-zero bit is at bit
* 0. This is useful for finding the
* greatest unsigned value that a bitfield
* can hold. No side-effects. Note that
* __SHIFTOUT_MASK(m) = __SHIFTOUT(m, m).
