BugLink: http://bugs.launchpad.net/bugs/1616107 Since implementing VLAN filtering in commit 05cc5a39 ("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while the interface is down: # ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10 RTNETLINK answers: Bad address and in dmesg (with bnx2x.debug=0x20): bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN configuration the interface is down Other drivers have no problem with this. Fix this peculiar behavior in the following way: - Accept requests to add/kill VID regardless of the device state. Maintain the requested list of VIDs in the bp->vlan_reg list. - If the device is up, try to configure the VID list into the hardware. If we run out of VLAN credits or encounter a failure configuring an entry, fall back to accepting all VLANs. If we successfully configure all entries from the list, turn the fallback off. - Use the same code for reconfiguring VLANs during NIC load. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1646857 During a PCI error recovery, like the ones provoked by EEH in the ppc64 platform, all IO to the device must be blocked while the recovery is completed. Current 8250_pci implementation only suspends the port instead of detaching it, which doesn't prevent incoming accesses like TIOCMGET and TIOCMSET calls from reaching the device. Those end up racing with the EEH recovery, crashing it. Similar races were also observed when opening the device and when shutting it down during recovery. This patch implements a more robust IO blockage for the 8250_pci recovery by unregistering the port at the beginning of the procedure and re-adding it afterwards. Since the port is detached from the uart layer, we can be sure that no request will make through to the device during recovery. This is similar to the solution used by the JSM serial driver. I thank Peter Hurley <peter@hurleysoftware.com> for valuable input on this one over one year ago. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1644505 It is possible to specify a user offset for the TOD clock, e.g. +2 hours. The TOD clock will carry this offset even if the clock is synchronized with STP. This makes the time stamps acquired with get_sync_clock() useless as another LPAR migth use a different TOD offset. Use the PTFF instrution to get the TOD epoch difference and subtract it from the TOD clock value to get a physical timestamp. As the epoch difference contains the sync check delta as well the LPAR offset value to the physical clock needs to be refreshed after each clock synchronization. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1648449 The NVMe driver currently configures a single MSI/MSIX interrupt for its admin queue, then later after initializing the NVMe controller and detecting the number of queues the controller can handle, the driver releases its MSI/MSIX interrupt and immediately re-configures enough MSI/MSIX interrupts for all the queues. However, on Amazon AWS instances with passthrough NVMe drives, this MSI/MSIX release/request causes failures of some of the interrupts, resulting in some (usually all but one or two but sometimes none) of the NVMe drive(s) failing to initialize. This combines the MSI/MSIX configurations, so all the MSI/MSIX configuration is done once. This avoids the interrupt failures, but it also results in more MSI/MSIX interrupts being configured than are needed. Signed-off-by:

This un-reverts the accidental reversion, to restore the NVMe driver to always use MSI/MSI-x interrupts. Signed-off-by:

BugLink: http://bugs.launchpad.net/bugs/1645453 commit 9db0ff53 upstream. When there is a CM id object that has port assigned to it, it means that the cm-id asked for the specific port that it should go by it, but if that port was removed (hot-unplug event) the cm-id was not updated.

BugLink: http://bugs.launchpad.net/bugs/1645453 commit 6f75c3fd upstream. Consider two devices, A and B, where B is a child of A, and B utilizes asynchronous suspend (it does not matter whether A is sync or async). If B fails to suspend_noirq() or suspend_late(), or is interrupted by a wakeup (pm_wakeup_pending()), then it aborts and sets the async_error variable. However, device A does not (immediately) check the async_error variable; it may continue to run its own suspend_noirq()/suspend_late() callback. This is bad. We can resolve this problem by doing our error and wakeup checking (particularly, for the async_error flag) after waiting for children to suspend, instead of before. This also helps align the logic for the noirq and late suspend cases with the logic in __device_suspend(). It's easy to observe this erroneous behavior by, for example, forcing a device to sleep a bit in its suspend_noirq() (to ensure the parent is waiting for the child to complete), then return an error, and watch the parent suspend_noirq() still get called. (Or similarly, fake a wakeup event at the right (or is it wrong?) time.) Fixes: de377b39 (PM / sleep: Asynchronous threads for suspend_late) Fixes: 28b6fd6e (PM / sleep: Asynchronous threads for suspend_noirq) Reported-by:
