The dma offset of a MPWQE (Multi-Packet WQE) in memory region
is fixed for all rounds. Calculate it once on creation time,
instead of in runtime. This also obsoletes the wqe argument in
the function.
In addition, optimize dma_info iterator calculation.

On POWER9, the Client Architecture Support (CAS) negotiation process
determines whether the guest operates in XIVE Legacy compatibility or
in XIVE exploitation mode. Now that we have initial guest support for
the XIVE interrupt controller, let's inform the hypervisor what we can
do.
The platform advertises the XIVE Exploitation Mode support using the
property "ibm,arch-vec-5-platform-support-vec-5", byte 23 bits 0-1 :
- 0b00 XIVE legacy mode Only
- 0b01 XIVE exploitation mode Only
- 0b10 XIVE legacy or exploitation mode
The OS asks for XIVE Exploitation Mode support using the property
"ibm,architecture-vec-5", byte 23 bits 0-1:
- 0b00 XIVE legacy mode Only
- 0b01 XIVE exploitation mode Only

The H_INT_ESB hcall() is used to issue a load or store to the ESB page
instead of using the MMIO pages. This can be used as a workaround on
some HW issues. The OS knows that this hcall should be used on an
interrupt source when the ESB hcall flag is set to 1 in the hcall
H_INT_GET_SOURCE_INFO.
To maintain the frontier between the xive frontend and backend, we
introduce a new xive operation 'esb_rw' to be used in the routines
doing memory accesses on the ESBs.

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.

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.

Since gclk (generated-clk) is now able to determine the rate of the
audio_pll, there is no need for classd to have a direct phandle to the
audio_pll while already having a phandle to gclk.
Thus, remove all mentions to aclk in classd driver and update macros and
variable names.
