copy the table from there.

cciss: Use pci_enable_msix_exact() instead of pci_enable_msix()

2014-04-22T01:02:08+00:00

As result of deprecation of MSI-X/MSI enablement functions
pci_enable_msix() and pci_enable_msi_block() all drivers
using these two interfaces need to be updated to use the
new pci_enable_msi_range()  or pci_enable_msi_exact()
and pci_enable_msix_range() or pci_enable_msix_exact()
interfaces.

cciss: Fallback to MSI rather than to INTx if MSI-X failed

2014-03-13T20:56:39+00:00

Currently the driver falls back to INTx mode when MSI-X
initialization failed. This is a suboptimal behaviour
for chips that also support MSI. This update changes that
behaviour and falls back to MSI mode in case MSI-X mode
initialization failed.

tree-wide: use reinit_completion instead of INIT_COMPLETION

2013-11-15T00:32:21+00:00

Use this new function to make code more comprehensible, since we are
reinitialzing the completion, not initializing.

cciss: fix info leak in cciss_ioctl32_passthru()

2013-09-25T00:00:26+00:00

The arg64 struct has a hole after ->buf_size which isn't cleared.  Or if
any of the calls to copy_from_user() fail then that would cause an
information leak as well.

This was assigned CVE-2013-2147.

cciss: set max scatter gather entries to 32 on P600

2013-09-11T22:56:59+00:00

At one time we used to set the maximum number of scatter gather elements
on all Smart Array controllers to 32.  At some point in time the
firmware began to write the "appropriate" value for each controller into
the config table.  The cciss driver would then read that and set
h->maxsgentries.

        h->maxsgentries = readl(&(h->cfgtable->MaxSGElements);

On the P600 that value is 544.  Under some workloads a significant
performance reduction may result.  This patch forces the P600 to use
only 32 scatter gather elements.  Other controllers are not affected.
