7eece5a084 [SCSI] qla4xxx: Prevent other port reinitialization during remove_adapter
remove ha flag AF_HBA_GOING_AWAY and added flag AF_HA_REMOVAL
to mark the other ISP-4xxx port to indicate that the driver is
being removed, so that the other port will not re-initialize
while in the process of removing the ha due to driver unload
or hba hotplug.

7edd9a7b28 [SCSI] qla4xxx: cleanup DDB relogin logic during initialization
Driver has capability to add device dynamically and present
them to OS, driver no longer need to wait for DDBs to come
online during driver initialization.
Driver still issues a relogin for DDBs that are not online,
but no longer wait for DDB to come online.

FW is not able to process mbox command if FW state is failed. This will cause

8c3adc796f [SCSI] ses: add subenclosure support
There have been many complaints that an enclosure with subenclosures
isn't attached to by the ses driver.   Until now, though, no-one had
been willing to provide access to one.

Subenclosures are added simply by flattening the tree (i.e. all
subenclosure devices show up under the one main device).  This may have
consequences if the naming is only unique per subenclosure, but that's a
bug for another day.  The tested array had no page 7, so no device
naming at all.  It also only had the disk devices on one of its
subenclosures (all the others had power, fans, temperature and various
sensors), so testing of this is fairly rudimentary.

0ea5c27583 [SCSI] bnx2fc: common free list for cleanup commands
Cleanup commands are issued to the firmware to cleanup any stuck ios
that are supposed to be implicitly aborted. In the worst case we can
have all scsi ios filling up the free_list and we may not be able to
allocate cleanup tasks. So the driver has to reserve free_list entries
to be able to allocate the cleanup tasks. This reserve free_list common
to all cpus is allocated as one additional entry in the per cpu
free_lists.

In bnx2fc_cmd_alloc(), there is a related fix to use get_cpu() for the
free_list_index.  This will prevent using the wrong index if the CPU
is preempted.

839900c69d [SCSI] bnx2fc: Avoid holding cq_lock when iounmap() is called
With kernel debugging enabled, holding cq_lock when calling
bnx2fc_free_session_resc() which calls iounmap() leads to a warning
stack trace [INFO: HARDIRQ-safe -> HARDIRQ-unsafe lock order detected].
iounmap() grabs a HARDIRQ-unsafe vmlist lock, so holding
spin_lock_bh(cq_lock) when calling iounmap() will trigger the LOCKDEP
warning.  Since cq_lock is required only to guard against deletion, hold
the lock just before freeing the cq.

05aea6e7e4 [SCSI] target: Remove unnecessary hba_dev_list walk and se_clear_dev_ports legacy code
This patch removes a legacy struct se_hba->hba_dev_list -> se_release_device_for_hba()
list walk in core_delete_hba(), which is no longer required while using configfs
VFS level parent/child struct config_group dependency referencing.  The reason
is because any struct se_hba->hba_dev_list-> struct se_device members are going
to have to be released via:

	rmdir /sys/kernel/config/target/core/$HBA/*

before rmdir release of struct se_hba via target_core_configfs.c:
target_core_call_delhbafromtarget() -> core_delete_hba()

	rmdir /sys/kernel/config/target/core/$HBA

to release struct se_hba in core_delete_hba().

This patch also removes the legacy se_clear_dev_ports() function, which is
left-over pre-configfs shutdown logic for when se_free_virtual_device()
was responsible for walking struct se_device->dev_sep_list and calling
core_dev_del_lun() for each individual active struct se_port->se_lun.

The reason this can be removed is because all struct se_device->dev_sep_list
-> struct se_port communication is done via configfs symlinks, which
means that an target fabric module's endpoints containg active struct
se_port(s) will have to be released via target_core_fabric_configfs.c:
target_fabric_port_unlink() via:

	unlink /sys/kernel/config/target/$FABRIC_MOD/$ENDPOINT/tpgt_$TPGT/lun/lun_$LUN_ID/<symlink>

before rmdir release of struct se_device in target_core_configfs.c:
target_core_drop_subdev() -> se_free_virtual_device() can happen via:

	rmdir /sys/kernel/config/target/core/$HBA/*

to release struct se_subsystem_dev in target_core_drop_subdev()

9940b97bb3 [SCSI] lpfc 8.3.22: Add support for PCI Adapter Failure
Periodically poll adapter registers to detect pci adapter failure
(reads return -1). On failure, take port offline, set error indicators
and wake up worker threads. Threads will take adapter offline.

877a55979c [SCSI] ses: show devices for enclosures with no page 7
enclosure page 7 gives us the "pretty" names of the enclosure slots.
Without a page 7, we can still use the enclosure code as long as we
make up numeric names for the slots. Unfortunately, the current code
fails to add any devices because the check for page 10 is in the wrong
place if we have no page 7.  Fix it so that devices show up even if
the enclosure has no page 7.

565d76cb7d zlib: slim down zlib_deflate() workspace when possible
Instead of always creating a huge (268K) deflate_workspace with the
maximum compression parameters (windowBits=15, memLevel=8), allow the
caller to obtain a smaller workspace by specifying smaller parameter
values.

For example, when capturing oops and panic reports to a medium with
limited capacity, such as NVRAM, compression may be the only way to
capture the whole report.  In this case, a small workspace (24K works
fine) is a win, whether you allocate the workspace when you need it (i.e.,
during an oops or panic) or at boot time.

I've verified that this patch works with all accepted values of windowBits
(positive and negative), memLevel, and compression level.

586f83e2b4 pnp: only assign IORESOURCE_DMA if CONFIG_ISA_DMA_API is enabled
IORESOURCE_DMA cannot be assigned without utilizing the interface
provided by CONFIG_ISA_DMA_API, specifically request_dma() and
free_dma().  Thus, there's a strict dependency on the config option and
limits IORESOURCE_DMA only to architectures that support ISA-style DMA.

ia64 is not one of those architectures, so pnp_check_dma() no longer
needs to be special-cased for that architecture.

pnp_assign_resources() will now return -EINVAL if IORESOURCE_DMA is
attempted on such a kernel.
