+Subject: ACPI: resource: Skip IRQ override on ASUS ExpertBook B1402CVA
+
+From: Hans de Goede <hdegoede@redhat.com>
+
+commit bd911485294a6f0596e4592ed442438015cffc8a upstream.
+
+Like various other ASUS ExpertBook-s, the ASUS ExpertBook B1402CVA
+has an ACPI DSDT table that describes IRQ 1 as ActiveLow while
+the kernel overrides it to EdgeHigh.
+
+This prevents the keyboard from working. To fix this issue, add this laptop
+to the skip_override_table so that the kernel does not override IRQ 1.

+
+From: Haiyang Zhang <haiyangz@microsoft.com>
+
+commit 85520856466ed6bc3b1ccb013cddac70ceb437db upstream.
+
+If VF NIC is registered earlier, NETDEV_REGISTER event is replayed,
+but NETDEV_POST_INIT is not.
+
+Move register_netdevice_notifier() earlier, so the call back
+function is set before probing.

+Subject: hv_netvsc: Mark VF as slave before exposing it to user-mode
+
+From: Long Li <longli@microsoft.com>
+
+commit c807d6cd089d2f4951baa838081ec5ae3e2360f8 upstream.
+
+When a VF is being exposed form the kernel, it should be marked as "slave"
+before exposing to the user-mode. The VF is not usable without netvsc
+running as master. The user-mode should never see a VF without the "slave"
+flag.
+
+This commit moves the code of setting the slave flag to the time before
+VF is exposed to user-mode.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+From: Jan Höppner <hoeppner@linux.ibm.com>
+
+commit db46cd1e0426f52999d50fa72cfa97fa39952885 upstream.
+
+In dasd_profile_start() the amount of requests on the device queue are
+counted. The access to the device queue is unprotected against
+concurrent access. With a lot of parallel I/O, especially with alias
+devices enabled, the device queue can change while dasd_profile_start()
+is accessing the queue. In the worst case this leads to a kernel panic
+due to incorrect pointer accesses.
+
+Fix this by taking the device lock before accessing the queue and
+counting the requests. Additionally the check for a valid profile data
+pointer can be done earlier to avoid unnecessary locking in a hot path.
