This is a wrong behavior because nofail allocations are not allowed to fail. Normal charge path simply forces the charge even if that means to cross the limit. Kmem accounting should be doing the same.

That leads to crashes when the system is stressed. Fix that by moving zhdr assignment up. While at it, protect against using already freed handles by using own local slots structure in z3fold_page_reclaim().

[PATCH v2] MIPS: ath79: Fix potentially missed IRQ handling during dispatch

by Koen Vandeputte

If both interrupts are set in the current implementation only the 1st will be handled and the 2nd will be skipped due to the "if else" condition. Fix this by using the same approach as done for QCA955x just below it.

[PATCH] cfg80211: Purge frame registrations on iftype change

by Denis Kenzior

Currently frame registrations are not purged, even when changing the interface type. This can lead to potentially weird / dangerous situations where frames possibly not relevant to a given interface type remain registered and mgmt_frame_register is not called for the no-longer-relevant frame types. The kernel currently relies on userspace apps to actually purge the registrations themselves, e.g. by closing the nl80211 socket associated with those frames. However, this requires multiple nl80211 sockets to be open by the userspace app, and for userspace to be aware of all state changes. This is not something that the kernel should rely on. This commit adds a call to cfg80211_mlme_purge_registrations() to forcefully remove any registrations left over prior to switching the iftype.
