I'm getting this when loading an externally built module:

infinity: Unknown symbol vsyscall_end
infinity: Unknown symbol vsyscall_ehdr

The module uses copy_from_user().  When ARCH=um, copy_from_user() is defined as inline, and uses FIXADDR_USER_END.  That macro is defined as VSYSCALL_END, which in turn is defined as vsyscall_end.  However, there's no EXPORT_SYMBOL(vsyscall_end).

This is in linux-2.6.16-rc4, with Jeff's patch set from last week.

TIA.
