* Fix build against v5.8 kernel (LP: #1884634)
  - backport: add genlmsg_parse()
  - backport: update include/uapi/linux/pci_regs.h
  - [NOUPSTREAM] iwlwifi: mvm: use 64-bit version of timespec
  - [NOUPSTREAM] cfg80211: use parallel_ops for genl
  - backports: netlink: fix nla_validate_nested()
  - netlink: rename nl80211_validate_nested() to nla_validate_nested()
  - ftrace: Rework event_create_dir()
  - nl80211: fix NL80211_ATTR_FTM_RESPONDER policy
  - [NOUPSTREAM] nl80211: pull in NLA_POLICY_EXACT_LEN_WARN() usage

[SRU Justifcation]

[Impact]
When compiled against linux-oem-5.6/linux-5.8 kernels on Focal, backport-iwlwifi-dkms gives numerous errors due to in kernel interface changes and fails the installation.

[Fix]
This backports several patches from upstream backport-iwlwifi, mainline kernel, and backports project.

[Test Case]
Tested build on 5.4.0-52-generic, 5.6.0-1032-oem and 5.8.0-25-generic on Focal. Since the current version 8324 has been marked obsoleted by 5.4 or newer in bug 1863583 and bug 1869587, built modules are not installed currently so no runtime tests are required.

[Regression Potential]
Low. So far backport-iwlwifi-dkms is still marked OBSOLETED_BY=5.4.0, so it has totally no effect in the runtime system. This will only change when future enablements based on LTS series Focal that relies on out-of-tree driver support from this package.

review: Approve

[You-Sheng Yang (vicamo)]

Was rejected due to too much changes while SRU back to Focal. Redo with cherry-picking necessary patches. Still need some more polishing and tests.

[You-Sheng Yang (vicamo)]

Updated commits to include only necessary changes backported from upstream backport-iwlwifi, mainline kernel, and backports project.

Need review & submit.

[Alberto Milone (albertomilone)]

It looks good to me. Approved, thanks.

+
+(Imported from upstream commit 50508d941c18 since newer kernels
+remove genl_family_attrbuf() entirely, so we can compile there)
+
+Over time, we really need to get rid of all of our global locking.
+One of the things needed is to use parallel_ops. This isn't really
+the most important (RTNL is much more important) but OTOH we just
+keep adding uses of genl_family_attrbuf() now. Use .parallel_ops to
+disallow this.

+Function nl80211_validate_nested() is not specific to nl80211, it's

+For consistency with other validation and parse functions, rename it to

+Subject: [PATCH] ftrace: Rework event_create_dir()
+
+Rework event_create_dir() to use an array of static data instead of
+function pointers where possible.
+
+The problem is that it would call the function pointer on module load
+before parse_args(), possibly even before jump_labels were initialized.
+Luckily the generated functions don't use jump_labels but it still seems
+fragile. It also gets in the way of changing when we make the module map
+executable.
+
+The generated function are basically calling trace_define_field() with a
+bunch of static arguments. So instead of a function, capture these
+arguments in a static array, avoiding the function call.
+
+Now there are a number of cases where the fields are dynamic (syscall
+arguments, kprobes and uprobes), in which case a static array does not
+work, for these we preserve the function call. Luckily all these cases
+are not related to modules and so we can retain the function call for
+them.
+
+Also fix up all broken tracepoint definitions that now generate a
+compile error.
