Pull netfslib fixes from David Howells:

 - Fix a lockdep warning and potential deadlock. This is takes the
   simple approach of offloading the write-to-cache done from within a
   network filesystem read to a worker thread to avoid taking the
   sb_writer lock from the cache backing filesystem whilst holding the
   mmap lock on an inode from the network filesystem.

   Jan Kara posits a scenario whereby this can cause deadlock[1], though
   it's quite complex and I think requires someone in userspace to
   actually do I/O on the cache files. Matthew Wilcox isn't so certain,
   though[2].

   An alternative way to fix this, suggested by Darrick Wong, might be
   to allow cachefiles to prevent userspace from performing I/O upon the
   file - something like an exclusive open - but that's beyond the scope
   of a fix here if we do want to make such a facility in the future.

 - In some of the error handling paths where netfs_ops->cleanup() is
   called, the arguments are transposed[3]. gcc doesn't complain because
   one of the parameters is void* and one of the values is void*.

Martyn Welch reports that his CPU port is unable to link where it has
been necessary to use one of the switch ports with an internal PHY for
the CPU port. The reason behind this is the port control register is
left forcing the link down, preventing traffic flow.

This occurs because during initialisation, phylink expects the link to
be down, and DSA forces the link down by synthesising a call to the
DSA drivers phylink_mac_link_down() method, but we don't touch the
forced-link state when we later reconfigure the port.

Resolve this by also unforcing the link state when we are operating in
PHY mode and the PPU is set to poll the PHY to retrieve link status
information.

When an IPv4 packet is received, the ip_rcv_core(...) sets the receiving
interface index into the IPv4 socket control block (v5.16-rc4,
net/ipv4/ip_input.c line 510):

    IPCB(skb)->iif = skb->skb_iif;

If that IPv4 packet is meant to be encapsulated in an outer IPv6+SRH
header, the seg6_do_srh_encap(...) performs the required encapsulation.
In this case, the seg6_do_srh_encap function clears the IPv6 socket control
block (v5.16-rc4 net/ipv6/seg6_iptunnel.c line 163):

    memset(IP6CB(skb), 0, sizeof(*IP6CB(skb)));

The memset(...) was introduced in commit ef489749 ("ipv6: sr: clear
IP6CB(skb) on SRH ip4ip6 encapsulation") a long time ago (2019-01-29).

Since the IPv6 socket control block and the IPv4 socket control block share
the same memory area (skb->cb), the receiving interface index info is lost
(IP6CB(skb)->iif is set to zero).

As a side effect, that condition triggers a NULL pointer dereference if
commit 0857d6f8 ("ipv6: When forwarding count rx stats on the orig
netdev") is applied.

To fix that issue, we set the IP6CB(skb)->iif with the index of the
receiving interface once again.

In line 800 (#1), nfp_cpp_area_alloc() allocates and initializes a
CPP area structure. But in line 807 (#2), when the cache is allocated
failed, this CPP area structure is not freed, which will result in
memory leak.

We can fix it by freeing the CPP area when the cache is allocated
failed (#2).

792 int nfp_cpp_area_cache_add(struct nfp_cpp *cpp, size_t size)
793 {
794 	struct nfp_cpp_area_cache *cache;
795 	struct nfp_cpp_area *area;

800	area = nfp_cpp_area_alloc(cpp, NFP_CPP_ID(7, NFP_CPP_ACTION_RW, 0),
801 				  0, size);
	// #1: allocates and initializes

802 	if (!area)
803 		return -ENOMEM;

805 	cache = kzalloc(sizeof(*cache), GFP_KERNEL);
806 	if (!cache)
807 		return -ENOMEM; // #2: missing free

817	return 0;

The CAN clock frequency is used when calculating the CAN bittiming
parameters. When wrong clock frequency is used, the device may end up
with wrong bittiming parameters, depending on user requested bittiming
parameters.

To avoid this, get the CAN clock frequency from the device. Various
existing Kvaser Leaf products use different CAN clocks.

[Why]
The HW interrupt gets disabled after S3/S4/reset so we don't receive
notifications for HPD or AUX from DMUB - leading to timeout and

Re-enable the interrupt after S3/S4/reset like we do for the other
DC interrupts.

Guard both instances of the outbox interrupt enable or we'll hang

The registration of XDP queue information is incorrect because the
RX queue id we use is invalid. When port->id == 0 it appears to works
as expected yet it's no longer the case when port->id != 0.

The problem arised while using a recent kernel version on the
MACCHIATOBin. This board has several ports:
 * eth0 and eth1 are 10Gbps interfaces ; both ports has port->id == 0;
 * eth2 is a 1Gbps interface with port->id != 0.

Code from xdp-tutorial (more specifically advanced03-AF_XDP) was used
to test packet capture and injection on all these interfaces. The XDP
kernel was simplified to:

	SEC("xdp_sock")
	int xdp_sock_prog(struct xdp_md *ctx)
	{
		int index = ctx->rx_queue_index;

		/* A set entry here means that the correspnding queue_id
		* has an active AF_XDP socket bound to it. */
		if (bpf_map_lookup_elem(&xsks_map, &index))
			return bpf_redirect_map(&xsks_map, index, 0);

		return XDP_PASS;
	}

Starting the program using:

	./af_xdp_user -d DEV

Gives the following result:

 * eth0 : ok
 * eth1 : ok
 * eth2 : no capture, no injection

Investigating the issue shows that XDP rx queues for eth2 are wrong:
XDP expects their id to be in the range [0..3] but we found them to be
in the range [32..35].

Trying to force rx queue ids using:

	./af_xdp_user -d eth2 -Q 32

fails as expected (we shall not have more than 4 queues).

When we register the XDP rx queue information (using
xdp_rxq_info_reg() in function mvpp2_rxq_init()) we tell it to use
rxq->id as the queue id. This value is computed as:

	rxq->id = port->id * max_rxq_count + queue_id

where max_rxq_count depends on the device version. In the MACCHIATOBin
case, this value is 32, meaning that rx queues on eth2 are numbered
from 32 to 35 - there are four of them.

Clearly, this is not the per-port queue id that XDP is expecting:
it wants a value in the range [0..3]. It shall directly use queue_id
which is stored in rxq->logic_rxq -- so let's use that value instead.

rxq->id is left untouched ; its value is indeed valid but it should
not be used in this context.

This is consistent with the remaining part of the code in
mvpp2_rxq_init().

With this change, packet capture is working as expected on all the
MACCHIATOBin ports.

'Commit 39f9895a ("vmxnet3: add support for 32 Tx/Rx queues")'
added support for 32Tx/Rx queues. Within that patch, value of
VMXNET3_LINUX_MIN_MSIX_VECT was updated.

However, there is a case (numvcpus = 2) which actually requires 3
intrs which matches VMXNET3_LINUX_MIN_MSIX_VECT which then is
treated as failure by stack to allocate more vectors. This patch
