Subject[PATCH][COMPAT] Allow for architectures to override {get,put}_compat_flock64
Hi Linus,

This is a small patch to allow some architecture to override the
generic implementations on {get,put}_compat_flock64 as some of them
(ia64 and maybe x86_64) will take alignment faults when accessing
the loff_t members of struct compat_flock64.

Requested by David Mosberger, modified by Dave Miller.
(Dave Miller would like these API's renamed, but that is another patch).

Please apply.
