[DRBD-user] Problem building 0.7.21 modules on x86_64 without CONFIG_COMPAT defined

[Harry Edmon]

On a x86_64 architecture system and a 2.6.17.11 kernel, if you do not have 
CONFIG_COMPAT defined (which is turned off when CONFIG_IA32_EMULATION is off) 
you get the following errors:

make -C /lib/modules/2.6.17.11/build SUBDIRS=/usr/src/drbd-0.7.21/drbd  modules

Memorizing module configuration ... done.

The resultant module will not load.  When I remove the "defined(CONFIG_X86_64)" 
clauses from drbd_main.c, it compiles, loads, and runs okay.
