Some source support MMIO stores on the ESB page to perform EOI. Let's
introduce a specific routine for this case even if this should be the
only use of it.

xive_poke_esb() is performing a load/read so it is better named as
xive_esb_read() as we will need to introduce a xive_esb_write()
routine. Also use the XIVE_ESB_LOAD_EOI offset when EOI'ing LSI
interrupts.

This is the framework for using XIVE in a PowerVM guest. The support
is very similar to the native one in a much simpler form.
Each source is associated with an Event State Buffer (ESB). This is a
two bit state machine which is used to trigger events. The bits are
named "P" (pending) and "Q" (queued) and can be controlled by MMIO.
The Guest OS registers event (or notifications) queues on which the HW
will post event data for a target to notify.
Instead of OPAL calls, a set of Hypervisors call are used to configure
the interrupt sources and the event/notification queues of the guest:
- H_INT_GET_SOURCE_INFO
used to obtain the address of the MMIO page of the Event State
Buffer (PQ bits) entry associated with the source.
- H_INT_SET_SOURCE_CONFIG
assigns a source to a "target".
- H_INT_GET_SOURCE_CONFIG
determines to which "target" and "priority" is assigned to a source
- H_INT_GET_QUEUE_INFO
returns the address of the notification management page associated
with the specified "target" and "priority".
- H_INT_SET_QUEUE_CONFIG
sets or resets the event queue for a given "target" and "priority".
It is also used to set the notification config associated with the
queue, only unconditional notification for the moment. Reset is
performed with a queue size of 0 and queueing is disabled in that
case.
- H_INT_GET_QUEUE_CONFIG
returns the queue settings for a given "target" and "priority".
- H_INT_RESET
resets all of the partition's interrupt exploitation structures to
their initial state, losing all configuration set via the hcalls
H_INT_SET_SOURCE_CONFIG and H_INT_SET_QUEUE_CONFIG.
- H_INT_SYNC
issue a synchronisation on a source to make sure sure all
notifications have reached their queue.
As for XICS, the XIVE interface for the guest is described in the
device tree under the "interrupt-controller" node. A couple of new
properties are specific to XIVE :
- "reg"
contains the base address and size of the thread interrupt
managnement areas (TIMA), also called rings, for the User level and
for the Guest OS level. Only the Guest OS level is taken into
account today.
- "ibm,xive-eq-sizes"
the size of the event queues. One cell per size supported, contains
log2 of size, in ascending order.
- "ibm,xive-lisn-ranges"
the interrupt numbers ranges assigned to the guest. These are
allocated using a simple bitmap.
and also :
- "/ibm,plat-res-int-priorities"
contains a list of priorities that the hypervisor has reserved for
its own use.
Tested with a QEMU XIVE model for pseries and with the Power hypervisor.

Because of the following code, net->num_tx_queues equals to

netvsc_drv.c:
alloc_etherdev_mq(sizeof(struct net_device_context),
VRSS_CHANNEL_MAX);
rndis_filter.c:
net_device->max_chn = min_t(u32, VRSS_CHANNEL_MAX, num_possible_rss_qs);

When a listener registers to the FIB notification chain it receives a
dump of the FIB entries and rules from existing address families by
invoking their dump operations.
While we call into these modules we need to make sure they aren't
removed. Do that by increasing their reference count before invoking
their dump operations and decrease it afterwards.

Instead of tracking wmem_queued and sk_mem_charge by incrementing
in the verdict SK_REDIRECT paths and decrementing in the tx work
path use skb_set_owner_w and sock_writeable helpers. This solves
a few issues with the current code. First, in SK_REDIRECT inc on
sk_wmem_queued and sk_mem_charge were being done without the peers
sock lock being held. Under stress this can result in accounting
errors when tx work and/or multiple verdict decisions are working
on the peer psock.
Additionally, this cleans up the code because we can rely on the
default destructor to decrement memory accounting on kfree_skb. Also
this will trigger sk_write_space when space becomes available on
kfree_skb() which wasn't happening before and prevent __sk_free
from being called until all in-flight packets are completed.

====================
inet_diag: report TCP MD5 signing keys and addresses
Allow userspace to retrieve MD5 signature keys and addresses configured
on TCP sockets through inet_diag.
Thanks to Eric Dumazet and Stephen Hemminger for their useful
explanations and feedback.
v5: - memset the whole netlink payload after it has been nla_reserve-d
in tcp_diag_put_md5sig (a third memset had to be added for
tcpm_key so we might as well have just one for entire region).
- move the nla_total_size call from inet_sk_attr_size to the
idiag_get_aux_size defined by protocols as they could add multiple
netlink attributes,
- add check for net_admin in tcp_diag_get_aux_size.
v4: - add new struct tcp_diag_md5sig to report the data instead of
tcp_md5sig to avoid wasting 112 bytes on every tcpm_addr,
- memset tcpm_addr on IPv4 addresses to avoid leaks,
- style fix in inet_diag_dump_one_icsk.
v3: - rename inet_diag_*md5sig in tcp_diag.c to tcp_diag_* for
consistency,
- don't lock the socket in tcp_diag_put_md5sig,
- add checks on md5sig_count in tcp_diag_put_md5sig to not create
the netlink attribute if the list is empty, and to avoid overflows
or memory leaks if the list has changed in the meantime.
v2: - move changes to tcp_diag.c and extend inet_diag_handler to allow
protocols to provide additional data on INET_DIAG_INFO,
- lock socket before calling tcp_diag_put_md5sig.
I also have a patch for iproute2/ss to test this change, making it print
this new attribute. I'm planning to polish and send it if this series
gets applied.

Changing the audio sample rate on the SolidRun Cubox disrupts the video
output. The Si5351 provides both the video clock (using PLLA on output
0) and the audio clock (using PLLB on output 2).
When the rate of clock output 2 is changed, it reconfigures PLLB, which
results in both PLLA and PLLB being reset. The reset of PLLA causes
clock output 0 to be disrupted, thereby causing a loss of sync by the
attached display device.
Hence, each time the audio sample rate changes (eg, when a video player
starts up, or when starting to play music) the video display momentarily
blanks while the Si5351 settles down. Prior to the commit below, this
behaviour did not happen.
Fix this by only resetting only the PLL which has been changed.

This allows gclk to determine audio_pll rate and set the parent rate
accordingly.
However, there are multiple children clocks that could technically
change the rate of audio_pll (via gck). With the rate locking, the first
consumer to enable the clock will be the one definitely setting the rate
of the clock.
Since audio IPs are most likely to request the same rate, we enforce
that the only clks able to modify gck rate are those of audio IPs.
To remain consistent, we deny other clocks to be children of audio_pll.

This new clock driver set allows to have a fractional divided clock that
would generate a precise clock particularly suitable for audio
applications.
The main audio pll clock has two children clocks: one that is connected
to the PMC, the other that can directly drive a pad. As these two routes
have different enable bits and different dividers and divider formulas,
they are handled by two different drivers. Each of them could modify the
rate of the main audio pll parent.
The main audio pll clock can output 620MHz to 700MHz.

The driver requests the current clk rate of each of its parent clocks to
decide whether a clock rate is suitable or not. It does not request
determine_rate from a parent clock which could request a rate change in
parent clock (i.e. there is no parent rate propagation).
We know the rate we want (passed along req argument of the function) and
the parent clock rate, thus we know the closest rounded divisor, we
don't need to iterate over the available divisors to find the best one
for a given clock.

The ssr_notifiers variable should be local, so add the missing static
storage classifier.

In addition to using GLINK for communication with the RPM it can be
used ontop of SMEM for communicating with remoteprocs, extend the
binding to also describe this case and reference the GLINK binding from
the affected remoteproc bindings.

Introduce the GLINK subdev, which allows the definition of a GLINK edge
as child of a remoteproc.

Older compilers think val may be used uninitialized:
arch/powerpc/lib/sstep.c: In function 'emulate_loadstore':
arch/powerpc/lib/sstep.c:2758:23: error: 'val' may be used uninitialized in this function
We know better, but initialise val to 0 to avoid breaking the build.
