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):
There's a funny historical reason for this -- Linux on Alpha originally
used OSF/1 syscall numbering and args for its own native syscalls.
No, our implementation need not actually reflect that -- but it's an
interesting historical detail perhaps we should write down somewhere.
Does that mean we don't need these syscalls?
