No need to use arch-specific memory barriers; switch to using generic
ones. The rmb()s were useless so drop them.

Under DNE mode, if we do not restrict the linkEA size, and if there
are too many cross-MDTs hard links to the same object, then it will
cause the llog overflow. On the other hand, too many linkEA entries
in the linkEA will serious affect the linkEA performance because we
only support to locate linkEA entry consecutively.
So we need to restrict the linkEA size. Currently, it is 4096 bytes,
that is independent from the backend. If too many hard links caused
the linkEA overflowed, we will add overflow timestamp in the linkEA
header.

Earlier the function interval_iterate_reverse function was
removed since it wasn't used by anyone. Now it is being
restored since it will be used by a future patch.

It's not necessary reassgin & re-adjust rq_mbits for replay
request in ptlrpc_set_bulk_mbits(), they all must have already
been correctly assigned before.
Such unecessary reassign could make the first matchbit not
PTLRPC_BULK_OPS_MASK aligned, that'll trigger LASSERT in
ptlrpc_register_bulk():
- ptlrpc_set_bulk_mbits() is called when first time sending
request, rq_mbits is set as xid, which is BULK_OPS aligned;
- ptlrpc_set_bulk_mbits() continue to adjust the mbits for
multi-bulk RPC, rq_mbits is not aligned anymore, then rq_xid
is changed accordingly if client is connecting to an old
server, so rq_xid became unaligned too;
- The request is replayed, ptlrpc_set_bulk_mbits() reassign
the rq_mbits as rq_xid, which isn't aligned already, but
ptlrpc_register_bulk() still assumes this value as the
first matchbits and LASSERT it's BULK_OPS aligned.
