Unlimited beers for a 21-line kernel patch?  Sign me up!

Totally untested, barely compiled patch below.

Ok, that didn't even build, let me try this for real now...

Some comments on the interface:

O_LARGEFILE can be unconditional, since offsets are not exposed to the caller.

Use the openat2 style arguments; limit the accepted flags to sane ones
(e.g. don't let this syscall create a file).

If we think this is worth it, might even good to either have it support
struct open_how or have it accept two flag arguments. We sure want
openat2()s RESOLVE_* flags in there.
