Regarding COMPAT_OSF1: I'm not totally sure, but it seems that Alpha's COMPAT_LINUX uses COMPAT_OSF1 as dependency (even if there is no proper dependency in the module), because there are osf1_* calls. Some more compat mess to untangle, it seems... In all cases, it's only a few functions that are just wrappers, so it probably shouldn't be too complicated to solve.
It's a total of 15 functions (I generated this list by building an alpha GENERIC kernel with COMPAT_OSF1 removed):
osf1_sys_wait4
osf1_sys_mount
osf1_sys_set_program_attributes
osf1_sys_setitimer
osf1_sys_select
osf1_sys_gettimeofday
osf1_sys_getrusage
osf1_sys_settimeofday
osf1_sys_utimes
osf1_sys_statfs
osf1_sys_fstatfs
osf1_sys_sysinfo
osf1_sys_usleep_thread
osf1_sys_getsysinfo
osf1_sys_setsysinfo
All of these are references from linux_sysent.o
