The async version of ufshcd_hold(async == true), which is only called in queuecommand path as for now, is expected to work in atomic context, thus it should not sleep or schedule out. When it runs into the condition that clocks are ON but link is still in hibern8 state, it should bail out without flushing the clock ungate work.

This sequence change is required to avoid dips in voltage during boot-up. Apparently, this dip is caused because in the original sequence, the regulators are initialized in lpm mode. And then when the load is set to high, and more current is drawn, than is allowed in lpm, the dip is seen.

There was report of an odd "Fix me..." log message, which was tracked down to the lpfc_els_rcv_rps() routine. This was in handling of a very old and obsolete ELS - Read Port Status. The RPS ELS was defined in FC-LS-1, but deprecated in FC-LS-2, and removed from all later FC-LS revisions. It was replaced by the Read Diagnostic Parameters (RDP) ELS and the Link Error Status Block descriptor. There should be no support for the RSP ELS. Remove support from driver.

Coverity reported a memory corruption error for the fdmi attributes routines: CID 15768 [Memory Corruption] Out-of-bounds access on FDMI Sloppy coding of the fmdi structures. In both the lpfc_fdmi_attr_def and lpfc_fdmi_reg_port_list structures, a field was placed at the start of payload that may have variable content. The field was given an arbitrary type (uint32_t). The code then uses the field name to derive an address, which it used in things such as memset and memcpy. The memset sizes or memcpy lengths were larger than the arbitrary type, thus coverity reported an error. Fix by replacing the arbitrary fields with the real field structures describing the payload.

When performing reset testing, the eq's list for related hwqs was getting corrupted. In cases where there is not a 1:1 eq to hwq, the eq is shared. The eq maintains a list of hwqs utilizing it in case of cpu offlining and polling. During the reset, the hwqs are being torn down so they can be recreated. The recreation was getting confused by seeing a non-null eq assignment on the eq and the eq list became corrupt. Correct by clearing the hdwq eq assignment when the hwq is cleaned up.

When driver is set to enable bb credit recovery, the switch displayed the setting as inactive. If the link bounces, it switches to Active. During link up processing, the driver currently does a MBX_READ_SPARAM followed by a MBX_CONFIG_LINK. These mbox commands are queued to be executed, one at a time and the completion is processed by the worker thread. Since the MBX_READ_SPARAM is done BEFORE the MBX_CONFIG_LINK, the BB_SC_N bit is never set the the returned values. BB Credit recovery status only gets set after the driver requests the feature in CONFIG_LINK, which is done after the link up. Thus the ordering of READ_SPARAM needs to follow the CONFIG_LINK. Fix by reordering so that READ_SPARAM is done after CONFIG_LINK. Added a HBA_DEFER_FLOGI flag so that any FLOGI handling waits until after the READ_SPARAM is done so that the proper BB credit value is set in the FLOGI payload.

The driver is occasionally seeing the following SLI Port error, requiring reset and reinit: Port Status Event: ... error 1=0x52004a01, error 2=0x218 The failure means an RQ timeout. That is, the adapter had received asynchronous receive frames, ran out of buffer slots to place the frames, and the driver did not replenish the buffer slots before a timeout occurred. The driver should not be so slow in replenishing buffers that a timeout can occur. When the driver received all the frames of a sequence, it allocates an IOCB to put the frames in. In a situation where there was no IOCB available for the frame of a sequence, the RQ buffer corresponding to the first frame of the sequence was not returned to the FW. Eventually, with enough traffic encountering the situation, the timeout occurred. Fix by releasing the buffer back to firmware whenever there is no IOCB for the first frame.

Connection failure processing depends on a daemon being present to (at least) stop the connection and start recovery. This is a problem on a multipath scenario, where if the daemon failed for whatever reason, the SCSI path is never marked as down, multipath won't perform the failover and IO to the device will be forever waiting for that connection to come back. This patch performs the connection failure entirely inside the kernel. This way, the failover can happen and pending IO can continue even if the daemon is dead. Once the daemon comes alive again, it can execute recovery procedures if applicable.

Pull new zonefs file system from Damien Le Moal: "Zonefs is a very simple file system exposing each zone of a zoned block device as a file. Unlike a regular file system with native zoned block device support (e.g. f2fs or the on-going btrfs effort), zonefs does not hide the sequential write constraint of zoned block devices to the user. As a result, zonefs is not a POSIX compliant file system. Its goal is to simplify the implementation of zoned block devices support in applications by replacing raw block device file accesses with a richer file based API, avoiding relying on direct block device file ioctls which may be more obscure to developers. One example of this approach is the implementation of LSM (log-structured merge) tree structures (such as used in RocksDB and LevelDB) on zoned block devices by allowing SSTables to be stored in a zone file similarly to a regular file system rather than as a range of sectors of a zoned device. The introduction of the higher level construct "one file is one zone" can help reducing the amount of changes needed in the application while at the same time allowing the use of zoned block devices with various programming languages other than C. Zonefs IO management implementation uses the new iomap generic code. Zonefs has been successfully tested using a functional test suite (available with zonefs userland format tool on github) and a prototype implementation of LevelDB on top of zonefs" * tag 'zonefs-5.6-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/dlemoal/zonefs: zonefs: Add documentation fs: New zonefs file system

Pull x86 fixes from Thomas Gleixner: "A set of fixes for X86: - Ensure that the PIT is set up when the local APIC is disable or configured in legacy mode. This is caused by an ordering issue introduced in the recent changes which skip PIT initialization when the TSC and APIC frequencies are already known. - Handle malformed SRAT tables during early ACPI parsing which caused an infinite loop anda boot hang. - Fix a long standing race in the affinity setting code which affects PCI devices with non-maskable MSI interrupts. The problem is caused by the non-atomic writes of the MSI address (destination APIC id) and data (vector) fields which the device uses to construct the MSI message. The non-atomic writes are mandated by PCI. If both fields change and the device raises an interrupt after writing address and before writing data, then the MSI block constructs a inconsistent message which causes interrupts to be lost and subsequent malfunction of the device. The fix is to redirect the interrupt to the new vector on the current CPU first and then switch it over to the new target CPU. This allows to observe an eventually raised interrupt in the transitional stage (old CPU, new vector) to be observed in the APIC IRR and retriggered on the new target CPU and the new vector. The potential spurious interrupts caused by this are harmless and can in the worst case expose a buggy driver (all handlers have to be able to deal with spurious interrupts as they can and do happen for various reasons). - Add the missing suspend/resume mechanism for the HYPERV hypercall page which prevents resume hibernation on HYPERV guests.
