Saurav Kashyap 7c3df1320e [SCSI] qla2xxx: Code changes to support new dynamic logging infrastructure.
The code is changed to support the new dynamic logging infrastructure.
Following are the levels added.
Default is 0 - no logging.  0x40000000 - Module Init & Probe.
0x20000000 - Mailbox Cmnds. 0x10000000 - Device Discovery.
0x08000000 - IO tracing.    0x04000000 - DPC Thread.
0x02000000 - Async events.  0x01000000 - Timer routines.
0x00800000 - User space.    0x00400000 - Task Management.
0x00200000 - AER/EEH.       0x00100000 - Multi Q.
0x00080000 - P3P Specific.  0x00040000 - Virtual Port.
0x00020000 - Buffer Dump.   0x00010000 - Misc.
0x7fffffff - For enabling all logs, can be too many logs.

Setting ql2xextended_error_logging module parameter to any of the above
value, will enable the debug for that particular level.
Do LOGICAL OR of the value to enable more than one level.

This patch removes the use of the port down retry counter as a mechanism to

Lalit Chandivade 86fbee86e9 [SCSI] qla2xxx: ensure flash operation and host reset via sg_reset are mutually exclusive
The problem occurring is a hw-race where there's an outstanding read-flash
operation occurring while the chip is being reset (done via an sg_reset script).
After the chip is paused, the read-flash operation never completes and the
DPC thread, while trying to complete the reset, is never able to recover,
as the HW appears to be hung...

The fix is to wait for outstanding flash operation prior to doing a sg_reset -h.
And to wait for reset to complete before any flash operations.

Note, during the wait, if any of the operation (reset/flash) does not complete,
failure is returned to the upper layer. The upper layer either need to
fail or retry.

Tejun Heo 5a0e3ad6af include cleanup: Update gfp.h and slab.h includes to prepare for breaking implicit slab.h inclusion from percpu.h
percpu.h is included by sched.h and module.h and thus ends up being
included when building most .c files.  percpu.h includes slab.h which
in turn includes gfp.h making everything defined by the two files
universally available and complicating inclusion dependencies.

percpu.h -> slab.h dependency is about to be removed.  Prepare for
this change by updating users of gfp and slab facilities include those
headers directly instead of assuming availability.  As this conversion
needs to touch large number of source files, the following script is
used as the basis of conversion.

  http://userweb.kernel.org/~tj/misc/slabh-sweep.py

The script does the followings.

* Scan files for gfp and slab usages and update includes such that
  only the necessary includes are there.  ie. if only gfp is used,
  gfp.h, if slab is used, slab.h.

* When the script inserts a new include, it looks at the include
  blocks and try to put the new include such that its order conforms
  to its surrounding.  It's put in the include block which contains
  core kernel includes, in the same order that the rest are ordered -
  alphabetical, Christmas tree, rev-Xmas-tree or at the end if there
  doesn't seem to be any matching order.

* If the script can't find a place to put a new include (mostly
  because the file doesn't have fitting include block), it prints out
  an error message indicating which .h file needs to be added to the
  file.

The conversion was done in the following steps.

1. The initial automatic conversion of all .c files updated slightly
   over 4000 files, deleting around 700 includes and adding ~480 gfp.h
   and ~3000 slab.h inclusions.  The script emitted errors for ~400
   files.

2. Each error was manually checked.  Some didn't need the inclusion,
   some needed manual addition while adding it to implementation .h or
   embedding .c file was more appropriate for others.  This step added
   inclusions to around 150 files.

3. The script was run again and the output was compared to the edits
   from #2 to make sure no file was left behind.

4. Several build tests were done and a couple of problems were fixed.
   e.g. lib/decompress_*.c used malloc/free() wrappers around slab
   APIs requiring slab.h to be added manually.

5. The script was run on all .h files but without automatically
   editing them as sprinkling gfp.h and slab.h inclusions around .h
   files could easily lead to inclusion dependency hell.  Most gfp.h
   inclusion directives were ignored as stuff from gfp.h was usually
   wildly available and often used in preprocessor macros.  Each
   slab.h inclusion directive was examined and added manually as
   necessary.

6. percpu.h was updated not to include slab.h.

7. Build test were done on the following configurations and failures
   were fixed.  CONFIG_GCOV_KERNEL was turned off for all tests (as my
   distributed build env didn't work with gcov compiles) and a few
   more options had to be turned off depending on archs to make things
   build (like ipr on powerpc/64 which failed due to missing writeq).

   * x86 and x86_64 UP and SMP allmodconfig and a custom test config.
   * powerpc and powerpc64 SMP allmodconfig
   * sparc and sparc64 SMP allmodconfig
   * ia64 SMP allmodconfig
   * s390 SMP allmodconfig
   * alpha SMP allmodconfig
   * um on x86_64 SMP allmodconfig

8. percpu.h modifications were reverted so that it could be applied as
   a separate patch and serve as bisection point.

Given the fact that I had only a couple of failures from tests on step
6, I'm fairly confident about the coverage of this conversion patch.
If there is a breakage, it's likely to be something in one of the arch
headers which should be easily discoverable easily on most builds of
the specific arch.

This patch makes the host device cache a pointer to the physical bus
device and provides an extra API for setting it (the normal API picks
it up from the parent).  This patch also modifies the qla2xxx and lpfc
vport logic to use the new DMA host setting API.

Anirban Chakraborty 7163ea8151 [SCSI] qla2xxx: Fix to ensure driver works in sinlge queue mode if multiqueue fails
When the multiqueue mode fails to work, the driver falls back on single
queue mode. This ensures that the firmware is reinitialized with single
queue options and all the resources are readjusted accordingly.
