	Accesses to this space are provided through a set of functions
	which allow 8-bit, 16-bit and 32-bit accesses; also
	known as byte, word and long.  These functions are
	<code class="function">inb</code>, <code class="function">inw</code>,
	<code class="function">inl</code>, <code class="function">outb</code>,
	<code class="function">outw</code> and <code class="function">outl</code>.
      </p><p>
	Some variants are provided for these functions.  Some devices
	require that accesses to their ports are slowed down.  This
	functionality is provided by appending a <code class="function">_p</code>
	to the end of the function.  There are also equivalents to memcpy.
	The <code class="function">ins</code> and <code class="function">outs</code>
	functions copy bytes, words or longs to the given port.
