+Subject: clk: samsung: Keep top BPLL mux on Exynos542x enabled
+
+From: Marek Szyprowski <m.szyprowski@samsung.com>
+
+commit 0212a0483b0a36cc94cfab882b3edbb41fcfe1cd upstream.
+
+BPLL clock must not be disabled because it is needed for proper DRAM
+operation. This is normally handled by respective memory devfreq driver,
+but when that driver is not yet probed or its probe has been deferred
+the clock might get disabled what causes board hang. Fix this by calling
+clk_prepare_enable() directly from the clock provider driver.

+Subject: gpio: siox: explicitly support only threaded irqs
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Ahmad Fatoum <a.fatoum@pengutronix.de>
+
+commit 45ccf6556720293323c20cda717756014ff63007 upstream.
+
+The gpio-siox driver uses handle_nested_irq() to implement its
+interrupt support. This is only capable of handling threaded irq
+actions. For a hardirq action it triggers a NULL pointer oops.
+(It calls action->thread_fn which is NULL then.)
+
+Prevent registration of a hardirq action by setting
+gpio_irq_chip::threaded to true.

+From: dillon min <dillon.minfei@gmail.com>
+
+commit 214b0e1ad01abf4c1f6d8d28fa096bf167e47cef upstream.
+
+The offset of regmap is incorrect, j * 8 is move to the
+wrong register.
+
+for example:
+
+asume i = 0, j = 1. we want to set KPY5 as interrupt
+falling edge mode, regmap[0][1] should be TC3589x_GPIOIBE1 0xcd
+but, regmap[i] + j * 8 = TC3589x_GPIOIBE0 + 8 ,point to 0xd4,
+this is TC3589x_GPIOIE2 not TC3589x_GPIOIBE1.

+Subject: scsi: iscsi: iscsi_tcp: Avoid holding spinlock while calling getpeername()
+
+From: Mark Mielke <mark.mielke@gmail.com>
+
+commit bcf3a2953d36bbfb9bd44ccb3db0897d935cc485 upstream.
+
+The kernel may fail to boot or devices may fail to come up when
+initializing iscsi_tcp devices starting with Linux 5.8.
+
+Commit a79af8a64d39 ("[SCSI] iscsi_tcp: use iscsi_conn_get_addr_param
+libiscsi function") introduced getpeername() within the session spinlock.
+
+Commit 1b66d253610c ("bpf: Add get{peer, sock}name attach types for
+sock_addr") introduced BPF_CGROUP_RUN_SA_PROG_LOCK() within getpeername(),
+which acquires a mutex and when used from iscsi_tcp devices can now lead to
+"BUG: scheduling while atomic:" and subsequent damage.
+
+Ensure that the spinlock is released before calling getpeername() or
+getsockname(). sock_hold() and sock_put() are used to ensure that the
+socket reference is preserved until after the getpeername() or
+getsockname() complete.
