[PATCH 2/9] backports: pm_qos: Add cpu_latency_qos_* functions

[Hauke Mehrtens]

The upstream commit fa048c59bf1b ("PM: QoS: Add CPU latency QoS API
wrappers") add the new cpu_latency_qos_* functions. In the initial
commit they are just calling the functions from the old API. Use this
first step to backport these functions. They are used by the ath10k and
ipw2100 driver.

[PATCH 3/9] backports: genetlink: Add genlmsg_parse()

[Hauke Mehrtens]

This adds the genlmsg_parse() function to the netlink backport. This was
added in upstream commit 8cb081746c03 ("netlink: make validation more
configurable for future strictness").

This function is used by the mac80211_hwsim driver.

[PATCH 4/9] backports: rculist: Add additional parameter to list_for_each_entry_rcu()

[Hauke Mehrtens]

Upstream commit 28875945ba98 ("rcu: Add support for consolidated-RCU
reader checking") adds a new paramater for lock checking to
list_for_each_entry_rcu().
Older kernel versions do not support CONFIG_PROVE_RCU_LIST, just
ignore the extra parameter.

[PATCH 5/9] backports: Add include/uapi/linux/virtio_ids.h

[Hauke Mehrtens]

Add the missing constant VIRTIO_ID_MAC80211_HWSIM.

This is a stable user space API, so it should be save to copy this file.

[PATCH 6/9] backports: virtio_config: Add virtio_find_vqs()

[Hauke Mehrtens]

The virtio_find_vqs() function is now used by the mac80211_hwsim driver.
This is just a wrapper around the find_vqs callback. The find_vqs
callback changed over the time.
With kernel 4.10 the names parameter was changed from "const char
*names[]" to "const char * const names[]".
With kernel 4.11 the "struct irq_affinity *desc" was added. We have to
define struct irq_affinity here for older kernel versions, because it
is used in this new parameter in kernel >= 4.12 this is already done in
the upstream header file.

[PATCH 7/9] backports: patches: avoid struct spi_delay usage

[Hauke Mehrtens]

The struct spi_transfer got a new member "struct spi_delay delay" in
upstream commit bebcfd272df6 ("spi: introduce `delay` field for
`spi_transfer` + spi_transfer_delay_exec()"), use the older interface in
older kernel versions.

[PATCH 8/9] backports: patches: Avoid struct ethtool_ops.supported_coalesce_params

[Hauke Mehrtens]

The supported_coalesce_params member was added to the struct ethtool_ops
in upstream commit 95cddcb5cc20 ("ethtool: add infrastructure for
centralized checking of coalescing parameters"). This prevents the usage
in kernel < 5.7.
