Max17042 driver has dummy hardIRQ function which
does nothing but waking the threaded handler.
This patch removes the hardIRQ function and also
modifies the interrupt type to falling edge. While
we are there, change the macros to comply with the
Data sheet.

Mimic the client side by providing a module parameter that turns off
idmapping in the auth_sys case, for backwards compatibility with NFSv2
and NFSv3.
Unlike in the client case, we don't have any way to negotiate, since the
client can return an error to us if it doesn't like the id that we
return to it in (for example) a getattr call.
However, it has always been possible for servers to return numeric id's,
and as far as we're aware clients have always been able to handle them.
Also, in the auth_sys case clients already need to have numeric id's the
same between client and server.
Therefore we believe it's safe to default this to on; but the module
parameter is available to return to previous behavior if this proves to
be a problem in some unexpected setup.

...and add a mechanism for switching between the "legacy" tracker and
the new one. The decision is made by looking to see whether the
v4recoverydir exists. If it does, then the legacy client tracker is
used.
If it's not, then the kernel will create a "cld" pipe in rpc_pipefs.
That pipe is used to talk to a daemon for handling the upcall.
Most of the data structures for the new client tracker are handled on a
per-namespace basis, so this upcall should be essentially ready for
containerization. For now however, nfsd just starts it by calling the
initialization and exit functions for init_net.
I'm making the assumption that at some point in the future we'll be able
to determine the net namespace from the nfs4_client. Until then, this
patch hardcodes init_net in those places. I've sprinkled some "FIXME"
comments around that code to attempt to make it clear where we'll need
to fix that up later.

Abstract out the mechanism that we use to track clients into a set of
client name tracking functions.
This gives us a mechanism to plug in a new set of client tracking
functions without disturbing the callers. It also gives us a way to
decide on what tracking scheme to use at runtime.
For now, this just looks like pointless abstraction, but later we'll
add a new alternate scheme for tracking clients on stable storage.
Note too that this patch anticipates the eventual containerization
of this code by passing in struct net pointers in places. No attempt
is made to containerize the legacy client tracker however.

We'll need a way to flag the nfs4_client as already being recorded on
stable storage so that we don't continually upcall. Currently, that's
recorded in the cl_firststate field of the client struct. Using an
entire u32 to store a flag is rather wasteful though.
The cl_cb_flags field is only using 2 bits right now, so repurpose that
to a generic flags field. Rename NFSD4_CLIENT_KILL to
NFSD4_CLIENT_CB_KILL to make it evident that it's part of the callback
flags. Add a mask that we can use for existing checks that look to see
whether any flags are set, so that the new flags don't interfere.
Convert all references to cl_firstate to the NFSD4_CLIENT_STABLE flag,
and add a new NFSD4_CLIENT_RECLAIM_COMPLETE flag.
