scsi: lpfc: Fix crash during Hardware error recovery on SLI3 adapters

2017-12-14T08:28:19+00:00

[ Upstream commit 5d181531bc6169e19a02a27d202cf0e982db9d0e ]

if REG_VPI fails, the driver was incorrectly issuing INIT_VFI
(a SLI4 command) on a SLI3 adapter.

scsi: qla2xxx: Fix ql_dump_buffer

[ Upstream commit 23456565acf6d452e0368f7380aecd584c019c67 ]

Recent printk changes for KERN_CONT cause this logging to be defectively
emitted on multiple lines.  Fix it.

Also reduces object size a trivial amount.

scsi: use dma_get_cache_alignment() as minimum DMA alignment

2017-12-14T08:28:11+00:00

commit 90addc6b3c9cda0146fbd62a08e234c2b224a80c upstream.

In non-coherent DMA mode, kernel uses cache flushing operations to
maintain I/O coherency, so scsi's block queue should be aligned to the
value returned by dma_get_cache_alignment().  Otherwise, If a DMA buffer
and a kernel structure share a same cache line, and if the kernel
structure has dirty data, cache_invalidate (no writeback) will cause
data corruption.

[ Upstream commit bb1181c9a8b46b6f10e749d9ed94480336445d7f ]

qlt_reset is called with Immedidate Notify IOCB only.
Current code wrongly cast it as ATIO IOCB.

scsi: lpfc: Add missing memory barrier

2017-11-21T08:23:24+00:00

[ Upstream commit 6b3b3bdb83b4ad51252d21bb13596db879e51850 ]

On loosely ordered memory systems (PPC for example), the WQE elements
were being updated in memory, but not necessarily flushed before the
separate doorbell was written to hw which would cause hw to dma the
WQE element. Thus, the hardware occasionally received partially
updated WQE data.

Add the memory barrier after updating the WQE memory.

scsi: ufs: add capability to keep auto bkops always enabled

2017-11-21T08:23:23+00:00

[ Upstream commit 4e768e7645ec4ffa92ee163643777b261ae97142 ]

UFS device requires to perform bkops (back ground operations) periodically
but host can control (via auto-bkops parameter of device) when device can
perform bkops based on its performance requirements. In general, host
would like to enable the device's auto-bkops only when it's not doing any
regular data transfer but sometimes device may not behave properly if host
keeps the auto-bkops disabled. This change adds the capability to let the
device auto-bkops always enabled except suspend.
