This file really needs the full module.h header file present, but
was just getting it implicitly before. Fix it up in advance so we
avoid build failures once the cleanup commit is present.

ERRATA
When READ_16 command is issued, the setting of SILI Bit in CDB is confirmed
and if SILI bit is off, the processing of relavent Errata is executed.
Added code for checking SILI bit for READ_16 as described in "SSC-4".

[Resend patch as per Bernd Schubert comment ]
Issue:
Device goes offline while doing aggressive HBA reset
along with IO using some utility.
Root cause:
FW goes into bad state due to aggressive reset. Softreset does not
help to recover FW. And also aggressive reset open up the window for
Error handling thread to kicked off at the same time HBA will be in
constant RESET loop as part of aggressive reset test case can lead
Device to goes offline.
Changes:
1. Added extra check as below inside eh_timed_out call back as below.
if(ioc->ioc_reset_in_progress) Rc = EH_TIMER_RESET
2. Removed " DOORBELL_ACTIVE" check for SAS controller from task
management context. Since SAS controller uses high priority queue
for task management. This check is not required for SAS controller.
3. Moved SoftReset call to HardReset from Task Mgmt context.

Driver will now schedule MPI event using "delay_work_queue_on" to
specify same CPU to be used to schedule work. Earlier it used
"delay_work_queue" which can cause migration of work due to kernel'
timer migration feature.

Find Non-Operation IOC and remove it from OS: Detecting
dead(non-functional) ioc will be done reading doorbell register value
from fault reset thread, which has been called from work thread
context after each specific interval. If doorbell value is 0xFFFFFFFF,
it will be considered as IOC is non-operational and marked as dead
ioc.
Once Dead IOC has been detected, it will be removed at pci layer using
"pci_remove_bus_device" API.

The max_sector setting is currently hard-coded in the driver to 8192
sectors (4MB transfers). Using new module parameter, if max_sectors is
specified at load time, the default of 8192 will be overridden.

When READ_6 command is issued, the setting of SILI Bit in CDB is confirmed and
if SILI bit is off, the processing of relavent Errata is executed.
Earlier we did not have check for SILI bit in READ_6 CDB.
As described in "ssc-r22", Now Driver is checking SILI bit for READ_6.

Several fixes as well where the +1 was missing.
Done via coccinelle scripts like:
@@
struct resource *ptr;
@@
- ptr->end - ptr->start + 1
+ resource_size(ptr)
and some grep and typing.
Mostly uncompiled, no cross-compilers.

Using C line continuation inside format strings is error prone.
Clean up the unintended whitespace introduced by misuse of \.
Neaten correctly used line continations as well for consistency.
drivers/scsi/arcmsr/arcmsr_hba.c has these errors as well,
but arcmsr needs a lot more work and the driver should likely be
moved to staging instead.

In-kernel disk event polling doesn't matter for legacy/fringe drivers
and may lead to infinite event loop if ->check_events() implementation
generates events on level condition instead of edge.
Now that block layer supports suppressing exporting unlisted events,
simply leaving disk->events cleared allows these drivers to keep the
internal revalidation behavior intact while avoiding weird
interactions with userland event handler.

Bus reset is not required for SAS Controller. It is valid for mptspi
and mptfc, but for mptsas it is not required. It is an extra work for
Error handling escallation for mptsas. Removing bus reset from error
handling will eventually speedup Error handling for SAS controller.

There's a branch at the end of this function that
is supposed to normalize the return value with what
the mid-layer expects. In this one case, we get it wrong.
Also increase the verbosity of the INFO level printk
at the end of mptscsih_abort to include the actual return value
and the scmd->serial_number. The reason being success
or failure is actually determined by the state of
the internal tag list when a TMF is issued, and not the
return value of the TMF cmd. The serial_number is also
used in this decision, thus it's useful to know for debugging
purposes.

Added missing release callback for file_operations mptctl_fops.
Without release callback there will be never freed. It remains on
mptctl's eent list even after the file is closed and released.

Move the mid-layer's ->queuecommand() invocation from being locked
with the host lock to being unlocked to facilitate speeding up the
critical path for drivers who don't need this lock taken anyway.
The patch below presents a simple SCSI host lock push-down as an
equivalent transformation. No locking or other behavior should change
with this patch. All existing bugs and locking orders are preserved.
Additionally, add one parameter to queuecommand,
struct Scsi_Host *
and remove one parameter from queuecommand,
void (*done)(struct scsi_cmnd *)
Scsi_Host* is a convenient pointer that most host drivers need anyway,
and 'done' is redundant to struct scsi_cmnd->scsi_done.
Minimal code disturbance was attempted with this change. Most drivers
needed only two one-line modifications for their host lock push-down.

In this code, 0 is returned on memory allocation failure, even though other
failures return -ENOMEM or other similar values.
A simplified version of the semantic match that finds this problem is as
follows: (http://coccinelle.lip6.fr/)

expression ret;
expression x,e1,e2,e3;

ret = 0
... when != ret = e1

The block device drivers have all gained new lock_kernel
calls from a recent pushdown, and some of the drivers
were already using the BKL before.
This turns the BKL into a set of per-driver mutexes.
Still need to check whether this is safe to do.
file=$1
name=$2
if grep -q lock_kernel ${file} ; then
if grep -q 'include.*linux.mutex.h' ${file} ; then
sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
else
sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}
fi
sed -i ${file} \
-e "/^#include.*linux.mutex.h/,$ {
1,/^\(static\|int\|long\)/ {
/^\(static\|int\|long\)/istatic DEFINE_MUTEX(${name}_mutex);
} }" \
-e "s/\(un\)*lock_kernel\>[ ]*()/mutex_\1lock(\&${name}_mutex)/g" \
-e '/[ ]*cycle_kernel_lock();/d'
else
sed -i -e '/include.*\<smp_lock.h\>/d' ${file} \
-e '/cycle_kernel_lock()/d'

All these files use the big kernel lock in a trivial
way to serialize their private file operations,
typically resulting from an earlier semi-automatic
pushdown from VFS.
None of these drivers appears to want to lock against
other code, and they all use the BKL as the top-level
lock in their file operations, meaning that there
is no lock-order inversion problem.
Consequently, we can remove the BKL completely,
replacing it with a per-file mutex in every case.
Using a scripted approach means we can avoid
typos.
file=$1
name=$2
if grep -q lock_kernel ${file} ; then
if grep -q 'include.*linux.mutex.h' ${file} ; then
sed -i '/include.*<linux\/smp_lock.h>/d' ${file}
else
sed -i 's/include.*<linux\/smp_lock.h>.*$/include <linux\/mutex.h>/g' ${file}
