+Subject: hwmon: (pmbus/core) Treat parameters as paged if on multiple pages
+
+[ Upstream commit 4a60570dce658e3f8885bbcf852430b99f65aca5 ]
+
+Some chips have attributes which exist on more than one page but the
+attribute is not presently marked as paged. This causes the attributes
+to be generated with the same label, which makes it impossible for
+userspace to tell them apart.
+
+Marking all such attributes as paged would result in the page suffix
+being added regardless of whether they were present on more than one
+page or not, which might break existing setups. Therefore, we add a
+second check which treats the attribute as paged, even if not marked as
+such, if it is present on multiple pages.

+Subject: s390/qeth: fix VLAN attribute in bridge_hostnotify udev event
+
+[ Upstream commit 335726195e460cb6b3f795b695bfd31f0ea70ef0 ]
+
+Enabling sysfs attribute bridge_hostnotify triggers a series of udev events
+for the MAC addresses of all currently connected peers. In case no VLAN is
+set for a peer, the device reports the corresponding MAC addresses with
+VLAN ID 4096. This currently results in attribute VLAN=4096 for all
+non-VLAN interfaces in the initial series of events after host-notify is
+enabled.
+
+Instead, no VLAN attribute should be reported in the udev event for
+non-VLAN interfaces.
+
+Only the initial events face this issue. For dynamic changes that are
+reported later, the device uses a validity flag.
+
+This also changes the code so that it now sets the VLAN attribute for
+MAC addresses with VID 0. On Linux, no qeth interface will ever be
+registered with VID 0: Linux kernel registers VID 0 on all network
+interfaces initially, but qeth will drop .ndo_vlan_rx_add_vid for VID 0.
+Peers with other OSs could register MACs with VID 0.

+struct ufs_dev_cmd is the main container that supports device management
+commands. In the case of a read descriptor request, we assume that the
+proper space was allocated in dev_cmd to hold the returning descriptor.
+
+This is no longer true, as there are flows that doesn't use dev_cmd for
+device management requests, and was wrong in the first place.

+Subject: sparc: perf: fix updated event period in response to
+ PERF_EVENT_IOC_PERIOD
+
+[ Upstream commit 56cd0aefa475079e9613085b14a0f05037518fed ]
+
+The PERF_EVENT_IOC_PERIOD ioctl command can be used to change the
+sample period of a running perf_event. Consequently, when calculating
+the next event period, the new period will only be considered after the
+previous one has overflowed.
+
+This patch changes the calculation of the remaining event ticks so that
+they are offset if the period has changed.
+
+See commit 3581fe0ef37c ("ARM: 7556/1: perf: fix updated event period in
+response to PERF_EVENT_IOC_PERIOD") for details.
