Whenever offload ramrod is issued, firmware wants driver to wait for max 5
secs, otherwise driver can initiate further corrective action. Similarly,
when termination ramrod is issued, irrespective of abortive or non-abortive
termination, driver should wait for 60 sec * max TCP-RT timeout.

When removing memory we need to remove the memory from the node
it was added to instead of looking up the node it should be in
in the device tree.
During testing we have seen scenarios where the affinity for a
LMB changes due to a partition migration or PRRN event. In these
cases the node the LMB exists in may not match the node the device
tree indicates it belongs in. This can lead to a system crash
when trying to DLPAR remove the LMB after a migration or PRRN
event. The current code looks up the node in the device tree to
remove the LMB from, the crash occurs when we try to offline this
node and it does not have any data, i.e. node_data[nid] == NULL.

This patch fixes issue reported by some of the customers, who discovered
that after cable pull scenario the devices disappear and path seems to
remain in blocked state. Once the device reappears, driver does not seem to
update path to online. This issue appears because of the defer flag
creating race condition where the same session reappears. This patch fixes
this issue by indicating SCSI-ML of device lost when
qlt_free_session_done() is called from qlt_unreg_sess().

All architectures which support stacktrace carry duplicated code and
do the stack storage and filtering at the architecture side.
Provide a consolidated interface with a callback function for consuming the
stack entries provided by the architecture specific stack walker. This
removes lots of duplicated code and allows to implement better filtering
than 'skip number of entries' in the future without touching any
architecture specific code.

The per cpu stack trace buffer usage pattern is odd at best. The buffer has
place for 512 stack trace entries on 64-bit and 1024 on 32-bit. When
interrupts or exceptions nest after the per cpu buffer was acquired the
stacktrace length is hardcoded to 8 entries. 512/1024 stack trace entries
in kernel stacks are unrealistic so the buffer is a complete waste.
Split the buffer into 4 nest levels, which are 128/256 entries per
level. This allows nesting contexts (interrupts, exceptions) to utilize the
cpu buffer for stack retrieval and avoids the fixed length allocation along
with the conditional execution pathes.

Replace the indirection through struct stack_trace by using the storage
array based interfaces.
The original code in all printing functions is really wrong. It allocates a
storage array on stack which is unused because depot_fetch_stack() does not
store anything in it. It overwrites the entries pointer in the stack_trace
struct so it points to the depot storage.

Replace the indirection through struct stack_trace with an invocation of
the storage array based interface. This results in less storage space and
indirection.
