TLS offload code casts record number to a u64. The buffer
should be aligned to 8 bytes, but its actually a __be64, and
the rest of the TLS code treats it as big int. Make the
offload callbacks take a byte array, drivers can make the
choice to do the ugly cast if they want to.
Prepare for copying the record number onto the stack by
defining a constant for max size of the byte array.

On Rockchip rk3288-based Chromebooks when you do a suspend/resume
cycle:
1. You lose the ability to detect an HDMI device being plugged in.
2. If you're using the i2c bus built in to dw_hdmi then it stops
working.
Let's add a hook to the core dw-hdmi driver so that we can call it in
dw_hdmi-rockchip in the next commit.
NOTE: the exact set of steps I've done here in resume come from
looking at the normal dw_hdmi init sequence in upstream Linux plus the
sequence that we did in downstream Chrome OS 3.14. Testing show that
it seems to work, but if an extra step is needed or something here is
not needed we could improve it.
As part of this change we'll refactor the hardware init bits of
dw-hdmi to happen all in one function and all at the same time. Since
we need to init the interrupt mutes before we request the IRQ, this
means moving the hardware init earlier in the function, but there
should be no problems with that. Also as part of this we now
unconditionally init the "i2c" parts of dw-hdmi, but again that ought
to be fine.

All drivers add all their connectors so there's no need to keep around an
array of available connectors. Instead we just put the useable (not
writeback) connectors in a temporary array using
drm_client_for_each_connector_iter() everytime we probe the outputs.
Other places where it's necessary to look at the connectors, we just
iterate over them using the same iterator function.
Rename functions which signature is changed since they will be moved to
drm_client in a later patch.

is encoded using the MSI message address, as opposed to standard
GICv2m, where the SPI number is encoded in the MSI message data.
In addition, the Graviton flavor of GICv2m is used along GICv3 (and not
GICv2).

Add support for RTA_NH_ID attribute to allow a user to specify a
nexthop id to use with a route. fc_nh_id is added to fib6_config to
hold the value passed in the RTA_NH_ID attribute. If a nexthop id
is given, the gateway, device, encap and multipath attributes can
not be set.
Update ip6_route_del to check metric and protocol before nexthop
specs. If fc_nh_id is set, then it must match the id in the route
entry. Since IPv6 allows delete of a cached entry (an exception),
add ip6_del_cached_rt_nh to cycle through all of the fib6_nh in
a fib entry if it is using a nexthop.

IPv6 has traditionally had a single fib6_nh per fib6_info. With
nexthops we can have multiple fib6_nh associated with a fib6_info.
Add a nexthop helper to invoke a callback for each fib6_nh in a
'struct nexthop'. If the callback returns non-0, the loop is
stopped and the return value passed to the caller.

So long as a struct hmm pointer exists, so should the struct mm it is
linked too. Hold the mmgrab() as soon as a hmm is created, and mmdrop() it
once the hmm refcount goes to zero.
Since mmdrop() (ie a 0 kref on struct mm) is now impossible with a !NULL
mm->hmm delete the hmm_hmm_destroy().

Ralph observes that hmm_range_register() can only be called by a driver
while a mirror is registered. Make this clear in the API by passing in the
mirror structure as a parameter.
This also simplifies understanding the lifetime model for struct hmm, as
the hmm pointer must be valid as part of a registered mirror so all we
need in hmm_register_range() is a simple kref_get.

Some older interconnect target modules need module internal clock
toggling quirks to reset properly. We've been doing this in the
platform code earlier, but need to be able to it directly in the
ti-sysc driver when we no longer rely on on the platform code.
Let's add reset handling for 1-wire, i2c and watchdog. Later on
we can add more modules like msdi and dss as they get tested.
For dra7 pcie, we should be able to just use the rstctrl reset
driver when available.
