+Subject: clk: renesas: rcar-usb2-clock-sel: Fix kernel NULL pointer
+ dereference
+
+From: Adam Ford <aford173@gmail.com>
+
+[ Upstream commit 1669a941f7c4844ae808cf441db51dde9e94db07 ]
+
+The probe was manually passing NULL instead of dev to devm_clk_hw_register.
+This caused a Unable to handle kernel NULL pointer dereference error.
+Fix this by passing 'dev'.

+Subject: perf/x86/intel/uncore: Fix integer overflow on 23 bit left shift of a
+ u32
+
+From: Colin Ian King <colin.king@canonical.com>
+
+[ Upstream commit 0b3a8738b76fe2087f7bc2bd59f4c78504c79180 ]
+
+The u32 variable pci_dword is being masked with 0x1fffffff and then left
+shifted 23 places. The shift is a u32 operation,so a value of 0x200 or
+more in pci_dword will overflow the u32 and only the bottow 32 bits
+are assigned to addr. I don't believe this was the original intent.
+Fix this by casting pci_dword to a resource_size_t to ensure no
+overflow occurs.
+
+Note that the mask and 12 bit left shift operation does not need this
+because the mask SNR_IMC_MMIO_MEM0_MASK and shift is always a 32 bit
+value.

+Subject: sched: Fix get_push_task() vs migrate_disable()
+
+From: Sebastian Andrzej Siewior <bigeasy@linutronix.de>
+
+[ Upstream commit e681dcbaa4b284454fecd09617f8b24231448446 ]
+
+push_rt_task() attempts to move the currently running task away if the
+next runnable task has migration disabled and therefore is pinned on the
+current CPU.
+
+The current task is retrieved via get_push_task() which only checks for
+nr_cpus_allowed == 1, but does not check whether the task has migration
+disabled and therefore cannot be moved either. The consequence is a
+pointless invocation of the migration thread which correctly observes
+that the task cannot be moved.
+
+Return NULL if the task has migration disabled and cannot be moved to
+another CPU.
