POWER "book S" (server class) cpus have a concept of "real mode" where
MMU translation is disabled... sort of.  In fact this can mean a bunch
of slightly different things when hypervisor mode and other
considerations are present.

We had some errors in edge cases here, so clean some things up and
correct them.

Some of those limitations caused problems with calculating the size of
the Real Mode Area of pseries guests, so continue on to clean up and
correct those calculations as well.

Changes since v5:
 * Fixed an error in the sense of a test (pointed out by Fabiano Rosas)
Changes since v4:
 * Some tiny cosmetic fixes to the original patches
 * Added a bunch of extra patches correcting RMA calculation
Changes since v3:
 * Fix style errors reported by checkpatch
Changes since v2:
 * Removed 32-bit hypervisor stubs more completely
 * Minor polish based on review comments
Changes since RFCv1:
 * Add a number of extra patches taking advantage of the initial
   cleanups
