Pull SCSI updates from James Bottomley:
"This is primarily another round of driver updates (lpfc, bfa, fcoe,
ipr) plus a new ufshcd driver. There shouldn't be anything
controversial in here (The final deletion of scsi proc_ops which
caused some build breakage has been held over until the next merge
window to give us more time to stabilise it).I'm afraid, with me moving continents at exactly the wrong time,
anything submitted after the merge window opened has been held over to
the next merge window."* tag 'scsi-misc' of git://git.kernel.org/pub/scm/linux/kernel/git/jejb/scsi-misc-2.6: (63 commits)

Pull PCI changes (including maintainer change) from Jesse Barnes:
"This pull has some good cleanups from Bjorn and Yinghai, as well as
some more code from Yinghai to better handle resource re-allocation
when enabled.There's also a new initcall_debug feature from Arjan which will print
out quirk timing information to help identify slow quirks for fixing
or refinement (Yinghai sent in a few patches to do just that once the
new debug code landed).Beyond that, I'm handing off PCI maintainership to Bjorn Helgaas.
He's been a core PCI and Linux contributor for some time now, and has
kindly volunteered to take over. I just don't feel I have the time
for PCI review and work that it deserves lately (I've taken on some
other projects), and haven't been as responsive lately as I'd like, so
I approached Bjorn asking if he'd like to manage things. He's going
to give it a try, and I'm confident he'll do at least as well as I
have in keeping the tree managed, patches flowing, and keeping things
stable."Fix up some fairly trivial conflicts due to other cleanups (mips device
resource fixup cleanups clashing with list handling cleanup, ppc iseries

Removed redundant calling of _scsih_probe_devices() from _scsih_probe as
it is getting called from _scsih_scan_finished.Also moved the function scsi_scan_host(shost) to get called after the
volumes on warp drive are reported to the OS. Otherwise by the time
the (ioc->hide_drives) flags is set, the volumes on warp drive
are reported to the OS already.Also modified the initialization of reply queues only in case of driver load

When computing reply_queue_count (the number of MSI-X vectors to use),
the driver doesioc->reply_queue_count = min_t(u8, ioc->cpu_count,
ioc->msix_vector_count);However, on a big machine, ioc->cpu_count could be outside the range
that fits in a u8; eg a system with 256 CPUs will end up
reply_queue_count set to 0.Fix this by calculating the minimum as ints and then letting the
assignment to reply_queue_count handle integer demotion.Signed-off-by: Roland Dreier

Commit 911ae9434f83 ("[SCSI] mpt2sas: Added NUNA IO support in driver
which uses multi-reply queue support of the HBA") added new
allocations to the beginning of mpt2sas_base_attach(), which means
directly returning an error on failure of mpt2sas_base_map_resources()
will leak those allocations.Fix this by doing "goto out_free_resources" in this place too, as the

The amount of memory required for tracking chain buffers is rather
large, and when the host credit count is big, memory allocation
failure occurs inside __get_free_pages.The fix is to limit the number of chains to 100,000. In addition,
the number of host credits is limited to 30,000 IOs. However this
limitation can be overridden this using the command line option
max_queue_depth. The algorithm for calculating the
reply_post_queue_depth is changed so that it is equal to
(reply_free_queue_depth + 16), previously it was (reply_free_queue_depth * 2).Signed-off-by: Nagalakshmi Nandigama

When an I/O request to a WarpDrive is timed out by SML and if the

The driver was setting the action to MPI2_CONFIG_ACTION_PAGE_READ_CURRENT,
which only returns active volumes. In order to get info on inactive volumes,
the driver needs to change the action to

iocstatus is MPI2_IOCSTATUS_CONFIG_INVALID_PAGE returned.
Added a change in the driver to remove the instance of

…lete while issued during creating a volume
This is due to the slave_configuration routine is getting called when
host reset is active, and config page reads are failing, and driver
attempts to added device with stale config data.To fix the issue, added error checking in slave_configure to check
for configuration pages failing, and return "1" so the device is
not configured. The config pages are failing if raid volume is
configured while issuing a host reset, thus driver is reading stale
data and proceeding to attempt to add. The fix is to return error
so the volume is not configured.Signed-off-by: Nagalakshmi Nandigama <nagalakshmi.nandigama@lsi.com>
