+Subject: ARM: 7696/1: Fix kexec by setting outer_cache.inv_all for Feroceon
+
+From: Illia Ragozin <illia.ragozin@grapecom.com>
+
+commit cd272d1ea71583170e95dde02c76166c7f9017e6 upstream.
+
+On Feroceon the L2 cache becomes non-coherent with the CPU
+when the L1 caches are disabled. Thus the L2 needs to be invalidated
+after both L1 caches are disabled.
+
+On kexec before the starting the code for relocation the kernel,
+the L1 caches are disabled in cpu_froc_fin (cpu_v7_proc_fin for Feroceon),
+but after L2 cache is never invalidated, because inv_all is not set
+in cache-feroceon-l2.c.
+So kernel relocation and decompression may has (and usually has) errors.
+Setting the function enables L2 invalidation and fixes the issue.

+Subject: ARM: 7698/1: perf: fix group validation when using enable_on_exec
+
+From: Will Deacon <will.deacon@arm.com>
+
+commit cb2d8b342aa084d1f3ac29966245dec9163677fb upstream.
+
+Events may be created with attr->disabled == 1 and attr->enable_on_exec
+== 1, which confuses the group validation code because events with the
+PERF_EVENT_STATE_OFF are not considered candidates for scheduling, which
+may lead to failure at group scheduling time.
+
+This patch fixes the validation check for ARM, so that events in the
+OFF state are still considered when enable_on_exec is true.

+Subject: ath9k_hw: change AR9580 initvals to fix a stability issue
+
+From: Felix Fietkau <nbd@openwrt.org>
+
+commit f09a878511997c25a76bf111a32f6b8345a701a5 upstream.
+
+The hardware parsing of Control Wrapper Frames needs to be disabled, as
+it has been causing spurious decryption error reports. The initvals for
+other chips have been updated to disable it, but AR9580 was left out for
+some reason.
