+Subject: alarmtimer: Use EOPNOTSUPP instead of ENOTSUPP
+
+From: Thadeu Lima de Souza Cascardo <cascardo@canonical.com>
+
+commit f18ddc13af981ce3c7b7f26925f099e7c6929aba upstream.
+
+ENOTSUPP is not supposed to be returned to userspace. This was found on an
+OpenPower machine, where the RTC does not support set_alarm.
+
+On that system, a clock_nanosleep(CLOCK_REALTIME_ALARM, ...) results in
+"524 Unknown error 524"
+
+Replace it with EOPNOTSUPP which results in the expected "95 Operation not
+supported" error.
+
+Fixes: 1c6b39ad3f01 (alarmtimers: Return -ENOTSUPP if no RTC device is present)

+Subject: ARM: zynq: Use memcpy_toio instead of memcpy on smp bring-up
+
+From: Luis Araneda <luaraneda@gmail.com>
+
+commit b7005d4ef4f3aa2dc24019ffba03a322557ac43d upstream.
+
+This fixes a kernel panic on memcpy when
+FORTIFY_SOURCE is enabled.
+
+The initial smp implementation on commit aa7eb2bb4e4a
+("arm: zynq: Add smp support")
+used memcpy, which worked fine until commit ee333554fed5
+("ARM: 8749/1: Kconfig: Add ARCH_HAS_FORTIFY_SOURCE")
+enabled overflow checks at runtime, producing a read
+overflow panic.
+
+The computed size of memcpy args are:
+- p_size (dst): 4294967295 = (size_t) -1
+- q_size (src): 1
+- size (len): 8
+
+Additionally, the memory is marked as __iomem, so one of
+the memcpy_* functions should be used for read/write.
+
+Fixes: aa7eb2bb4e4a ("arm: zynq: Add smp support")

+Subject: media: sn9c20x: Add MSI MS-1039 laptop to flip_dmi_table
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit 7e0bb5828311f811309bed5749528ca04992af2f upstream.
+
+Like a bunch of other MSI laptops the MS-1039 uses a 0c45:627b
+SN9C201 + OV7660 webcam which is mounted upside down.
+
+Add it to the sn9c20x flip_dmi_table to deal with this.
