+Subject: cpufreq: powernow-k8: pass policy rather than use cpufreq_cpu_get()
+
+From: Colin Ian King <colin.king@canonical.com>
+
+commit 943bdd0cecad06da8392a33093230e30e501eccc upstream.
+
+Currently there is an unlikely case where cpufreq_cpu_get() returns a
+NULL policy and this will cause a NULL pointer dereference later on.
+
+Fix this by passing the policy to transition_frequency_fidvid() from
+the caller and hence eliminating the need for the cpufreq_cpu_get()
+and cpufreq_cpu_put().
+
+Thanks to Viresh Kumar for suggesting the fix.
+
+Addresses-Coverity: ("Dereference null return")
+Fixes: b43a7ffbf33b ("cpufreq: Notify all policy->cpus in cpufreq_notify_transition()")

+Subject: iommu/intel: Fix memleak in intel_irq_remapping_alloc
+
+From: Dinghao Liu <dinghao.liu@zju.edu.cn>
+
+commit ff2b46d7cff80d27d82f7f3252711f4ca1666129 upstream.
+
+When irq_domain_get_irq_data() or irqd_cfg() fails
+at i == 0, data allocated by kzalloc() has not been
+freed before returning, which leads to memleak.
