This contains the following changes:

a) changes from Intel to support the new microcode data format
   (backward compatible of course)

b) changes from me to remove the no longer needed features of the driver,
   namely we don't need to keep a copy of applied microcode in kernel
   memory.

   This feature was hardly useful in the days of regular devfs
   /dev/cpu/microcode file and now it is completely useless so I removed
   it (after taking into account all the feedback on linux-kernel I
   received since the announcement of the intention to do this)

These are rather critical because otherwise we can't really say Linux
fully supports the very latest Intel cpus (which require microcode in
the new format).
