powerpc: Don't use cache to zero pages
pmap_zero_page() may be called on uncached pages, so using the cache to
zero uncached pages may trigger a fault.

nvme: Notify namespace changes better
When we get a namespace notification, we have to reconstrut the
namespace to get the new identification data from the namespace. For
each namespace in the AEN, we will reconstrict it before we call the
notification. We also flag it as changed for the duration of the change
callback (prior versions of the patch needed to keep track, but we no
longer do, so this bit may be removed). Note when we've seen the
namespace so we can notify when it goes away.

nda: React to namespace change events
Register for AC_GETDEV_CHANGED. When we receive a namespace
notification, we only create a new device if it was unconfigured. If it
was configured, generate this async event. Rely on the fact that we
reconstruct namespace to just get the data from the identify data and
call disk_resised.

nvme: Fix backwards sense of error condition
b21e67875bf0c tested for the good condition, not the error condition, so
we'd never do anything else in this function. This was causing certain
logging not to happen, and also prevented forthcoming namespace size
change code from working as well.

LinuxKPI: 802.11: use a _check rather than a _protected version for linksta
Switch to link_sta_dereference_check rather than _protected to access
the value. The actual problem we hit was elsewhere though.

LinuxKPI: 802.11: implement mtx support for ieee80211_iterate_interfaces
Implement the lockdep_assert_wiphy call for
ieee80211_iterate_active_interfaces_mtx() to avoid a warning when
used and to make sure callers comply with assumptions.
Leave an "IMPROVE" note as we can likely switch another of the multiple
callers to RCU.

iwlwifi/mld: only get tid after checking that it is a dataqos frame
Like we did for mvm, only get the tid after all the other checks are
done by the function in order to not trigger an assert. Linux will
likely return a random value there which later is not used as the
driver does an early return. In LinuxKPI we do check that the frame
assumptions hold up, which does not go so well for a random frame.

LinuxKPI: 802.11: initialize a backpointer on the link_sta
iwlwifi/mld uses the back pointer in iwl_mld_link_sta_from_mac80211().
Initialize it to make BE200 cards work again.
