Some MediaTek UFS platforms support high-performance mode that inline
encryption engine can be boosted while UFS is not clock-gated.
The high-performance mode will be enabled if all below conditions are
well-declaired in device tree,
- Proper platform-specific compatible string which enables the host
capability "UFS_MTK_CAP_BOOST_CRYPT_ENGINE".
- "dvfsrc-vcore" node is available in this platform.
- Required minimum vcore voltage for high-performance mode.
- Clock mux and clock parents of inline encryption engine for both
"low-power mode" and "high-performance mode".

In the discovery thread, ibmvfc does a vhost->task_set++ without any lock
held. This could result in two targets getting the same cancel key, which
could have strange effects in error recovery. The actual probability of
this occurring should be extremely small, since this should all be done in
a single threaded loop from the discovery thread, but let's fix it up
anyway to be safe.

VirtIO 1.0 spec says:
The removed and rescan events ... when sent for LUN 0, they MAY
apply to the entire target so the driver can ask the initiator
to rescan the target to detect this.
This change introduces the behaviour described above by scanning the entire
SCSI target when LUN is set to 0. This is both a functional and a
performance fix. It aligns the driver with the spec and allows control
planes to hotplug targets with large numbers of LUNs without having to
request a RESCAN for each one of them.

When a canister on a FS9100, or similar storage, running in NPIV mode, is
rebooted, its WWPNs will fail over to another canister. When this occurs,
we see a WWPN going away from the fabric at one N-Port ID, and, a short
time later, the same WWPN appears at a different N-Port ID. When the
canister is fully operational again, the WWPNs fail back to the original
canister. If there is any I/O outstanding to the target when this occurs,
it will result in the implicit logout the ibmvfc driver issues before
removing the rport to fail. When the WWPN then shows up at a different
N-Port ID, and we issue a PLOGI to it, the VIOS will see that it still has
a login for this WWPN at the old N-Port ID, which results in the VIOS
simulating a link down / link up sequence to the client, in order to get
the VIOS and client LPAR in sync.
The patch below improves the way we handle this scenario so as to avoid the
link bounce, which affects all targets under the virtual host adapter. The
change is to utilize the Move Login MAD, which will work even when I/O is
outstanding to the target. The change only alters the target state machine
for the case where the implicit logout fails prior to deleting the rport.
If this implicit logout fails, we defer deleting the ibmvfc_target object
after calling fc_remote_port_delete. This enables us to later retry the
implicit logout after terminate_rport_io occurs, or to issue the Move Login
request if a WWPN shows up at a new N-Port ID prior to this occurring.
This has been tested by IBM's storage interoperability team on a FS9100,
forcing the failover to occur. With debug tracing enabled in the ibmvfc
driver, we confirmed the move login was sent in this scenario and confirmed
the link bounce no longer occurred.
