ioport unification was broken for 32-bit; it was missing
the acutal pushf/popf EFLAGS manipulation (set_iopl_mask()).
Also, use of volatile looks like leftover cruft.

ioport_{32|64}.c unification.
This patch unifies the code from the ioport_32.c and ioport_64.c files.
Tested and working fine with i386 and x86_64 kernels.
