This is v8 of the last 3 patches from v7, with an additional clean-up for
the pagetable.c code. The rest of the series has landed in -tip.

The patches are:
- 1: Further clean up on pagetable.c.
- 2: Last part of Baoquan's decoupling the physical address and virtual
address randomization of kernel text.
- 3: Remove upper bound on physical address range.
- 4: Remove lower bound on physical address range.

Thanks for putting up with my attempts at this, and for all the review!
Things really do look much cleaner. :)

v7->v8:
- extracted identity map initialization function to be part of the
called interface, renamed appropriately to initialize_identity_maps().
- added copyright to pagetable.c for clarity.
- shuffled initialization of mapping_info around again for good measure.
- refactored remaining patches to include call to initialize_identity_maps().
