oops. sorry, I just realized I missed the makefile part. I changed the config symbol to CONFIG_LGUEST_HYPERVISOR so I should change it on the makefile as well.
reposting an updated patch for testing:

lguest: makes sure CONFIG_LGUEST is defined when building it as a module and built-in into the kernel.
 
This will make sure CONFIG_LGUEST is set when building the linux hypervisor example code as both module and built-in,
so that the LGUEST_* offsets will be generated for both cases in asm-offset.h.
