+Subject: nohz: Prevent a timer interrupt storm in tick_nohz_stop_sched_tick()
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit 5d62c183f9e9df1deeea0906d099a94e8a43047a upstream.
+
+The conditions in irq_exit() to invoke tick_nohz_irq_exit() which
+subsequently invokes tick_nohz_stop_sched_tick() are:
+
+ if ((idle_cpu(cpu) && !need_resched()) || tick_nohz_full_cpu(cpu))
+
+If need_resched() is not set, but a timer softirq is pending then this is
+an indication that the softirq code punted and delegated the execution to
+softirqd. need_resched() is not true because the current interrupted task
+takes precedence over softirqd.
+
+Invoking tick_nohz_irq_exit() in this case can cause an endless loop of
+timer interrupts because the timer wheel contains an expired timer, but
+softirqs are not yet executed. So it returns an immediate expiry request,
+which causes the timer to fire immediately again. Lather, rinse and
+repeat....
+
+Prevent that by adding a check for a pending timer soft interrupt to the
+conditions in tick_nohz_stop_sched_tick() which avoid calling
+get_next_timer_interrupt(). That keeps the tick sched timer on the tick and
+prevents a repetitive programming of an already expired timer.

+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit fd45bb77ad682be728d1002431d77b8c73342836 upstream.
+
+The timer start debug function is called before the proper timer base is
+set. As a consequence the trace data contains the stale CPU and flags
+values.
+
+Call the debug function after setting the new base and flags.

+Subject: timers: Reinitialize per cpu bases on hotplug
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit 26456f87aca7157c057de65c9414b37f1ab881d1 upstream.
+
+The timer wheel bases are not (re)initialized on CPU hotplug. That leaves
+them with a potentially stale clk and next_expiry valuem, which can cause
+trouble then the CPU is plugged.
+
+Add a prepare callback which forwards the clock, sets next_expiry to far in
+the future and reset the control flags to a known state.
+
+Set base->must_forward_clk so the first timer which is queued will try to
+forward the clock to current jiffies.

+Subject: timers: Use deferrable base independent of base::nohz_active
+
+From: Anna-Maria Gleixner <anna-maria@linutronix.de>
+
+commit ced6d5c11d3e7b342f1a80f908e6756ebd4b8ddd upstream.
+
+During boot and before base::nohz_active is set in the timer bases, deferrable
+timers are enqueued into the standard timer base. This works correctly as
+long as base::nohz_active is false.
+
+Once it base::nohz_active is set and a timer which was enqueued before that
+is accessed the lock selector code choses the lock of the deferred
+base. This causes unlocked access to the standard base and in case the
+timer is removed it does not clear the pending flag in the standard base
+bitmap which causes get_next_timer_interrupt() to return bogus values.
+
+To prevent that, the deferrable timers must be enqueued in the deferrable
+base, even when base::nohz_active is not set. Those deferrable timers also
+need to be expired unconditional.

+From: Mathias Nyman <mathias.nyman@linux.intel.com>
+
+commit 07b9f12864d16c3a861aef4817eb1efccbc5d0e6 upstream.
+
+USB 3.1 devices are not detected as 3.1 capable since 4.15-rc3 due to a
+off by one in commit 81cf4a45360f ("USB: core: Add type-specific length
+check of BOS descriptors")
+
+It uses USB_DT_USB_SSP_CAP_SIZE() to get SSP capability size which takes
+the zero based SSAC as argument, not the actual count of sublink speed
+attributes.
+
+USB3 spec 9.6.2.5 says "The number of Sublink Speed Attributes = SSAC + 1."
+
+The type-specific length check patch was added to stable and needs to be
+fixed there as well

+
+but need sendsetup = true for the NMEA port to make it work properly.
+
+Simplify the patch compared to v1 as suggested by Bjørn Mork by taking
+advantage of the fact that existing devices work with sendsetup = true
+too.
+
+Use sendsetup = true for the NMEA interface of QCSERIAL_SWI and add
+DEVICE_SWI entries for the EM7565 PID 0x9091 and the EM7565 QDL PID
+0x9090.
+
+Tests with several MC73xx/MC74xx/MC77xx devices have been performed in
+order to verify backward compatibility.

+Subject: x86/smpboot: Remove stale TLB flush invocations
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit 322f8b8b340c824aef891342b0f5795d15e11562 upstream.
+
+smpboot_setup_warm_reset_vector() and smpboot_restore_warm_reset_vector()
+invoke local_flush_tlb() for no obvious reason.
+
+Digging in history revealed that the original code in the 2.1 era added
+those because the code manipulated a swapper_pg_dir pagetable entry. The
+pagetable manipulation was removed long ago in the 2.3 timeframe, but the
+TLB flush invocations stayed around forever.
+
+Remove them along with the pointless pr_debug()s which come from the same 2.1
+change.
