The xenpf_dom0_console_t structure can grow as more data is added, and
hence we need to check that the fields we accesses have been filled by
Xen. The only extra field FreeBSD currently uses is the top 32 bits
for the frame buffer physical address.
Note that this field is present in all the versions that make the
information available from the platform hypercall interface, so the
check here is mostly cosmetic, and to remember us that newly added
fields require checking the size of the returned data.

FreeBSD Kernel Source:
This directory contains the source files and build glue that make up the FreeBSD kernel and its modules, including both original and contributed software.
Kernel configuration files are located in the conf/
subdirectory of each
architecture. GENERIC
is the configuration used in release builds. NOTES
contains documentation of all possible entries. LINT
is a compile-only
configuration used to maximize build coverage and detect regressions.
