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

Here is a patch [1] that untangles the dependency. Cross-compile-tested on
alpha from amd64.
