For 4032, context reset was the same as chip reset, and any firmware
issue was recovered by performing a chip reset.
For 82xx, the iSCSI firmware runs along with FCoE and the NIC
firmware contexts, and an error encountered doesnot essentially mean
that a chip reset is necessary.
Perform Chip resets only in the following cases:
1. Mailbox system error.
2. Mailbox command timeout.
3. fw_heartbeat_counter counter stops incrementing.
For all other cases, only perform a context reset.
1. Command Completion with an invalid srb.
2. Other mailbox failures.

There could be multiple userspace entities creating/destroying/
recoverying sessions and also the kernel's iscsi drivers could
be doing this too. If the userspace apps do try to manage the kernel
ones it can get the driver/fw out of sync and cause the user to
loose the root disk, oopses or ping ponging becasue userspace
wants to do one thing but the kernel manager thought we
are trying to do another.
This patch fixes the problem by just exporting the pid of
the entity that created the session. Userspace programs like
iscsid, iscsiadm, iscsistart, qlogic's tools, etc, can then
figure out which sessions they own and only manage them.

When computing reply_queue_count (the number of MSI-X vectors to use),
the driver does
ioc->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.

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
rest of the function does.

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).

When an I/O request to a WarpDrive is timed out by SML and if the
I/O request to the WarpDrive is sent as direct I/O then the aborted
direct I/O will be retried as normal Volume I/O and which results
in failure of Target Reset and results in host reset.
The fix is to not retry a failed IO to volume when the original
IO was sent as direct IO with an ioc status
MPI2_IOCSTATUS_SCSI_TASK_TERMINATED.

slave_destroy callback when all the LUNS have been deleted
If the sas_device->starget to NULL from slave_destroy callback for LUN=1
even though LUN=0 exist, results in entire target getting deleted.
To resolve the issue, the driver should only set sas_device->starget to
NULL when all the LUNS have been deleted from the slave_destroy.

Detection of Dead IOC has been done in fault_reset_work thread.
If IOC Doorbell is 0xFFFFFFFF, it will be detected as non-operation/DEAD IOC.
When a DEAD IOC is detected, the code is modified to remove that IOC and
all its attached devices from OS.
The PCI layer API pci_remove_bus_device() is called to remove the dead IOC.

"sense_len" was declared as int type but actually it only stores a
u16 value that comes from hardware. The cast to u16 in min_t()
confuses static analysis because it truncates the int to u16 so I've
fixed the declaration to reflect that "sense_len" is just a u16.
Also there was a call to cpu_to_be16() which I've changed to
be16_to_cpu(). The functions are equivalent, but obviously the
hardware is big endian and we're doing the min_t() comparison on CPU
endian values.
This whole patch is just a cleanup and doesn't affect how the code
works.

Using strlcpy instead of memcpy makes the strlen() calls superfluous
and also ensures zero-termination of the copied string.
At the same time get rid of the magic constant 50.
Actually, I can't see why copying the callback name is necessary
instead of simply storing a pointer to it (just like to the callback
function itself), but that goes beyond the scope of this fix.
