mvsas is giving a General protection fault when it encounters an expander attached ATA device. Analysis of mvs_task_prep_ata() shows that the driver is assuming all ATA devices are locally attached and obtaining the phy mask by indexing the local phy table (in the HBA structure) with the phy id. Since expanders have many more phys than the HBA, this is causing the index into the HBA phy table to overflow and returning rubbish as the pointer. mvs_task_prep_ssp() instead does the phy mask using the port properties. Mirror this in mvs_task_prep_ata() to fix the panic. Reported-by:

On systems with shared interrupts the interrupt routine might be called as soon as the interrupt is enabled. As this might happen before pci_set_drvdata() is called the system would crash. Reported-by:

We only want to steer the I/O completion towards a queue, but don't actually access any per-CPU data, so the raw_ version is fine to use and avoids the warnings when using smp_processor_id(). Signed-off-by:

The current string_get_size() overflows when the device size goes over 2^64 bytes because the string helper routine computes the suffix from the size in bytes. However, the entirety of Linux thinks in terms of blocks, not bytes, so this will artificially induce an overflow on very large devices. Fix this by making the function string_get_size() take blocks and the block size instead of bytes. This should allow us to keep working until the current SCSI standard overflows. Also fix virtio_blk and mmc (both of which were also artificially multiplying by the block size to pass a byte side to string_get_size()). The mathematics of this is pretty simple: we're taking a product of size in blocks (S) and block size (B) and trying to re-express this in exponential form: S*B = R*N^E (where N, the exponent is either 1000 or 1024) and R < N. Mathematically, S = RS*N^ES and B=RB*N^EB, so if RS*RB < N it's easy to see that S*B = RS*RB*N^(ES+EB). However, if RS*BS > N, we can see that this can be re-expressed as RS*BS = R*N (where R = RS*BS/N < N) so the whole exponent becomes R*N^(ES+EB+1) [jejb: fix incorrect 32 bit do_div spotted by kbuild test robot <fengguang.wu@intel.com>] Acked-by:

Some implementation of UFS host controller HW might have some non-standard behaviours (quirks) when compared to behaviour specified by UFSHCI specification. This patch add support to allow specifying all such quirks to standard UFS host controller driver so standard driver takes them into account. In this change a UFSHCD_QUIRK_DELAY_BEFORE_DME_CMDS is introduced, where a minimum delay of 1ms is required before DME commands for stability purposes. Signed-off-by:

Sometimes, specific information about the UFS controller revision is required in order to determine certain operations or execute controller dependent quirks. In order to avoid reading the controller revision multiple times, we simply read it once and save this information in internal structure. Signed-off-by:

For FA-WWPN is enabled port, if NPIV created on that port and, if port link is brought down, then WWPN was restored from flash for both physical and NPIV port. This will result in NPIV port and physical port sharing same WWPN. Any application refreshing ports information will not be able to scan NPIV port because of this behavior. So while restoring WWPN, only restore physical port WWPN. Signed-off-by:

Currently, the driver plays off the fact that older sli4 adapters have a different rpi access pattern that allowed for the rpi reference to be released earlier in the teardown sequence, allowing the driver to recycle the rpi value sooner. Newer sli4 adapters have a different access pattern that requires us to wait for a later mailbox completion. This changes the put call location on the newer sli4 adapters. Symptoms of the error are "0110 ELS" and the "0372 iotag" errors. Signed-off-by:

Fix host reset escalation killing all IOs. SLI-3 adapters will use a new host template. The template differs from SLI-4 adapters in that it does not have an eh_host_reset_handler. Lpfc has traditionally never had a host_reset. The host reset handler was added when we ran into a stuck hardware condition on a SLI-4 adapter. The host_reset will reset and reinit the pci function, clearing the hardware condition. Unfortunately, the host reset handler uses attach/detach code paths, which makes scsi_add_host() and scsi_remove_host() calls. Meaning, a host_reset will completely remove the scsi_host from the system. As a new call to scsi_add_host() is made, the shost# changes, which results in completely new scsi_devices and device names. All the older scsi devices on the old shost# are now orphaned and unrecoverable. We realize we need to re-implement the host_reset_handler so the scsi_host stays registered across the host_reset, but that will be a rather lengthy effort. In the short term, we had an immediate need to restore the SLI-3 devices to their working behavior, with the easiest path being to remove their host_reset handler. Signed-off-by:
