+Subject: ALSA: hda/realtek - Couldn't detect Mic if booting with headset plugged
+
+From: Hui Wang <hui.wang@canonical.com>
+
+commit 3f74249057827c5f6676c41c18f6be12ce1469ce upstream.
+
+We found a Mic detection issue on many Lenovo laptops, those laptops
+belong to differnt models and they have different audio design like
+internal mic connects to the codec or PCH, they all have this problem,
+the problem is if plugging a headset before powerup/reboot the
+machine, after booting up, the headphone could be detected but Mic
+couldn't. If we plug out and plug in the headset, both headphone and
+Mic could be detected then.
+
+Through debugging we found the codec on those laptops are same, it is
+alc257, and if we don't disable the 3k pulldown in alc256_shutup(),
+the issue will be fixed. So far there is no pop noise or power
+consumption regression on those laptops after this change.

+Subject: arch/x86/lib/usercopy_64.c: fix __copy_user_flushcache() cache writeback
+
+From: Mikulas Patocka <mpatocka@redhat.com>
+
+commit a1cd6c2ae47ee10ff21e62475685d5b399e2ed4a upstream.
+
+If we copy less than 8 bytes and if the destination crosses a cache
+line, __copy_user_flushcache would invalidate only the first cache line.
+
+This patch makes it invalidate the second cache line as well.
+
+Fixes: 0aed55af88345b ("x86, uaccess: introduce copy_from_iter_flushcache for pmem / cache-bypass operations")

+Subject: x86/ioapic: Unbreak check_timer()
+
+From: Thomas Gleixner <tglx@linutronix.de>
+
+commit 86a82ae0b5095ea24c55898a3f025791e7958b21 upstream.
+
+Several people reported in the kernel bugzilla that between v4.12 and v4.13
+the magic which works around broken hardware and BIOSes to find the proper
+timer interrupt delivery mode stopped working for some older affected
+platforms which need to fall back to ExtINT delivery mode.
+
+The reason is that the core code changed to keep track of the masked and
+disabled state of an interrupt line more accurately to avoid the expensive
+hardware operations.
+
+That broke an assumption in i8259_make_irq() which invokes
+
+ disable_irq_nosync();
+ irq_set_chip_and_handler();
+ enable_irq();
+
+Up to v4.12 this worked because enable_irq() unconditionally unmasked the
+interrupt line, but after the state tracking improvements this is not
+longer the case because the IO/APIC uses lazy disabling. So the line state
+is unmasked which means that enable_irq() does not call into the new irq
+chip to unmask it.
+
+In principle this is a shortcoming of the core code, but it's more than
+unclear whether the core code should try to reset state. At least this
+cannot be done unconditionally as that would break other existing use cases
+where the chip type is changed, e.g. when changing the trigger type, but
+the callers expect the state to be preserved.
+
+As the way how check_timer() is switching the delivery modes is truly
+unique, the obvious fix is to simply unmask the i8259 manually after
+changing the mode to ExtINT delivery and switching the irq chip to the
+legacy PIC.
+
+Note, that the fixes tag is not really precise, but identifies the commit
+which broke the assumptions in the IO/APIC and i8259 code and that's the
+kernel version to which this needs to be backported.
