+/* I/O access is restricted to ISA port space (ports 0..65535).
+   Modern devices hopefully are sane enough not to put any performance
+   critical registers in i/o space.
+
+   On the first call to ioperm, the entire (E)ISA port space is mapped
+   into the virtual address space at address io.base.  mprotect calls
+   are then used to enable/disable access to ports.  Per page, there
+   are PAGE_SIZE>>IO_SHIFT I/O ports (e.g., 256 ports on a Low Cost Alpha
+   based system using 8KB pages).
+
+   Keep in mind that this code should be able to run in a 32bit address
+   space.  It is therefore unreasonable to expect mmap'ing the entire

+
+   The following code tries hard to be optimal.  A general assumption
+   (which is true according to the data books I have) is that
+
+	2 * xchg	is more expensive than	pushl + movl + popl
+
+   Beside this a neat trick is used.  The calling conventions for Linux
+   tell that among the registers used for parameters %ecx and %edx need
+   not be saved.  Beside this we may clobber this registers even when
+   they are not used for parameter passing.
+
+   As a result one can see below that we save the content of the %ebx
+   register in the %edx register when we have less than 3 arguments
+   (2 * movl is less expensive than pushl + popl).
+
+   Second unlike for the other registers we don't save the content of
+   %ecx and %edx when we have more than 1 and 2 registers resp.
+
+   The code below might look a bit long but we have to take care for
+   the pipelined processors (i586).  Here the `pushl' and `popl'
+   instructions are marked as NP (not pairable) but the exception is
+   two consecutive of these instruction.  This gives no penalty on
+   other processors though.  */

+   Note that __sigsetjmp() did NOT flush the register stack.  Instead,
+   we do it here since __longjmp() is usually much less frequently
+   invoked than __sigsetjmp(). The only difficulty is that __sigsetjmp()
+   didn't (and wouldn't be able to) save ar.rnat either.  This is a problem
+   because if we're not careful, we could end up loading random NaT bits.
+   There are two cases:
+
+	(i)  ar.bsp < ia64_rse_rnat_addr(jmpbuf.ar_bsp)
+		ar.rnat contains the desired bits---preserve ar.rnat
+		across loadrs and write to ar.bspstore
+
+	(ii) ar.bsp >= ia64_rse_rnat_addr(jmpbuf.ar_bsp)
+		The desired ar.rnat is stored in
+		ia64_rse_rnat_addr(jmpbuf.ar_bsp).  Load those
+		bits into ar.rnat after setting ar.bspstore. */
