2018-05-31rtc: sprd: Add new RTC power down check methodBaolin Wang
We should use the new method to check if RTC was powered down, which is more solid. Since we have introduced power control and power status registers, and we just check if the power status is the default value (0x96), if yes that means the RTC has been powered down. Meanwhile We can set the power control register to be one valid value to change the power status to indicate RTC device is valid now.

2018-05-31rtc: sun6i: Fix bit_idx value for clk_register_gateMichael Trimarchi
clk-gate core will take bit_idx through clk_register_gate and then do clk_gate_ops by using BIT(bit_idx), but rtc-sun6i is passing bit_idx as BIT(bit_idx) it becomes BIT(BIT(bit_idx) which is wrong and eventually external gate clock is not enabling.

2018-05-31Merge branch 'bridge-vlan-notify'David S. Miller
Petr Machata says: ==================== net: bridge: Notify about bridge VLANs In commit 946a11e7408e ("mlxsw: spectrum_span: Allow bridge for gretap mirror"), mlxsw got support for offloading mirror-to-gretap such that the underlay packet path involves a bridge. In that case, the offload is also influenced by PVID setting of said bridge. However, changes to VLAN configuration of the bridge itself do not generate switchdev notifications, so there's no mechanism to prod mlxsw to update the offload when these settings change. In this patchset, the problem is resolved by distributing the switchdev notification SWITCHDEV_OBJ_ID_PORT_VLAN also for configuration changes on bridge VLANs. Since stacked devices distribute the notification to lower devices, such event eventually reaches the driver, which can determine whether it's a bridge or port VLAN by inspecting orig_dev. To keep things consistent, the newly-distributed notifications observe the same protocol as the existing ones: dual prepare/commit, with -EOPNOTSUPP indicating lack of support, even though there's currently nothing to prepare for and nothing to support. Correspondingly, all switchdev drivers have been updated to return -EOPNOTSUPP for bridge VLAN notifications. In patches #1 and #2, the code base is changed to support the following additions: functions br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del() are introduced to simplify sending notifications; and br_vlan_add_existing() is introduced to later make it simpler to add error-handling code for the case of configuring a preexisting VLAN on bridge CPU port. In patches #3-#6, respectively for mlxsw, rocker, DSA and DPAA2 ethsw, the new notifications (which are not enabled yet) are ignored to maintain the current behavior. In patch #7, the notification is actually enabled. In patch #8, mlxsw is changed to update offloads of mirror-to-gre also for bridge-related notifications. Changes from v3 to v4: - In patch #1, separate variable declarations from program logic. - Add patch #2. - In patch #7, add error handling around a newly-introduced call to br_switchdev_port_vlan_add(). - Rephrase commit messages of patches #3-#6 to explain motivation for the change. Changes from v2 to v3: - Add a fallback definition for br_switchdev_port_obj_add() and br_switchdev_port_obj_del() when !CONFIG_NET_SWITCHDEV. Changes from v1 to v2: - Rename br_switchdev_port_obj_add() and br_switchdev_port_obj_del() to br_switchdev_port_vlan_add() and br_switchdev_port_vlan_del(), and move from br_vlan.c to br_switchdev.c. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
2018-05-31mlxsw: spectrum_switchdev: Schedule respin during trans preparePetr Machata
Since there's no special support for the bridge events, the driver returns -EOPNOTSUPP, and thus the commit never happens. Therefore schedule respin during the prepare stage: there's no real difference one way or another. This fixes the problem that mirror-to-gretap offload wouldn't adapt to changes in bridge vlan configuration right away and another notification would have to arrive for mlxsw to catch up.

2018-05-31IB/iser: Do not reduce max_sectorsSergey Gorenko
The iSER driver reduces max_sectors. For example, if you load the ib_iser module with max_sectors=1024, you will see that /sys/class/block/<bdev>/queue/max_hw_sectors_kb is 508. It is an incorrect value. The expected value is (max_sectors * sector_size) / 1024 = 512. Reducing of max_sectors can cause performance degradation due to unnecessary splitting of IO requests. The number of pages per MR has been fixed here, so there is no longer any need to reduce max_sectors.

2018-05-31Staging:rtl888eu:include Fix CamelCase issueJanani Sankara Babu
This patch is created to solve the CamelCase issue. The members 'IEs' and 'IELength' of struct wlan_bssid_ex are being modified to 'ie' and 'ie_length' to solve the issue. And the places where these variables are referenced inside rtl8188eu driver are also changed.

2018-05-31arm64: KVM: Handle guest's ARCH_WORKAROUND_2 requestsMarc Zyngier
In order to forward the guest's ARCH_WORKAROUND_2 calls to EL3, add a small(-ish) sequence to handle it at EL2. Special care must be taken to track the state of the guest itself by updating the workaround flags. We also rely on patching to enable calls into the firmware. Note that since we need to execute branches, this always executes after the Spectre-v2 mitigation has been applied.

2018-05-31arm64: KVM: Add ARCH_WORKAROUND_2 support for guestsMarc Zyngier
In order to offer ARCH_WORKAROUND_2 support to guests, we need a bit of infrastructure. Let's add a flag indicating whether or not the guest uses SSBD mitigation. Depending on the state of this flag, allow KVM to disable ARCH_WORKAROUND_2 before entering the guest, and enable it when exiting it.
