[ Upstream commit 2abae62a26a265129b364d8c1ef3be55e2c01309 ]
The qpn allocation logic has a WARN_ON() that intends to detect the use of an index that will introduce bits in the lower order bits of the QOS bits in the QPN.
Unfortunately, it has the following bugs: - it misfires when wrapping QPN allocation for non-QOS - it doesn't correctly detect low order QOS bits (despite the comment)
The WARN_ON() should not be applied to non-QOS (qos_shift == 1).
Additionally, it SHOULD test the qpn bits per the table below:
2 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, 0, sc0], qp bit 1 always 0* 3-4 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, 0, sc1, sc0], qp bits [21] always 0 5-8 data VLs: [qp7, qp6, qp5, qp4, qp3, qp2, qp1] ^ [ 0, 0, 0, 0, sc2, sc1, sc0] qp bits [321] always 0
Fix by qualifying the warning for qos_shift > 1 and producing the correct mask to insure the above bits are zero without generating a superfluous warning.

[ Upstream commit 62394708f3e01c9f2be6be74eb6305bae1ed924f ]
When non-bridged, non-vlan'ed mv88e6xxx port is moving down, error message is logged:
failed to kill vid 0081/0 for device eth_cu_1000_4
This is caused by call from __vlan_vid_del() with vin set to zero, over call chain this results into _mv88e6xxx_port_vlan_del() called with vid=0, and mv88e6xxx_vtu_get() called from there returns -EINVAL.
On symmetric path moving port up, call goes through mv88e6xxx_port_vlan_prepare() that calls mv88e6xxx_port_check_hw_vlan() that returns -EOPNOTSUPP for zero vid.
This patch changes mv88e6xxx_vtu_get() to also return -EOPNOTSUPP for zero vid, then this error code is explicitly cleared in dsa_slave_vlan_rx_kill_vid() and error message is no longer logged.

When doing a loopback test at copper ports, the serdes loopback and the phy loopback will fail, because of the adjust link had not finished, and phy not ready.
Adds sleep between adjust link and test process to fix it.

In get_vdev_port_node_info(), 'node_info->vdev_port.name' is allcoated by kstrdup_const(), and it returns NULL when fails. So 'node_info->vdev_port.name' should be checked.

[ 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.
