Bit map: Contains the PXIBK flags that are subject to
relocation. These bits are defined sequentially,
regardless of how they are defined in HCPPXIBK.
This yields a consistent mapping that ensures
compatibility when a guest is relocated between
systems at differing service levels.
Names in the comments column indicate the control
block byte which contains the flag. This name is
subject to change if the flag definition changes.
====> NEVER change bits which already exist here.
====> NEVER change the order of bits in this section.
====> ALWAYS add new bits at the end of this section,
together with new flag bytes as required.

Data: Contains all HCPPXIBK data that is subject to
relocation, except for flag bits, which are
handled separately.
All fields are defined as XLnn to avoid alignment
warnings and to pack the data efficiently.
====> NEVER change fields which already exist here.
====> NEVER change the order of fields in this section.
====> ALWAYS add new fields at the end of this section.
