acf3368ffb scsi: Fix up files implicitly depending on module.h inclusion
The module.h header was implicitly present everywhere, so files
with no explicit include of the module infrastructure would build
anyway.  We are now removing the implicit include, and so we need
to call out the module.h file that we need explicitly.

bd5354511d [SCSI] be2iscsi: Fix for case where task->sc was cleanedup earlier
This patch fixes a bug where the task->sc was cleaned up earlier on a
different thread, possibly abort, and the completion comes later.

This was causing a crash which has been reported in multiple places

e528586079 [SCSI] be2iscsi: Fix for kdump failure
This patch fixes the Kdump failure reported by Redhat wich was caused by
be2iscsi resetting the Chip when be2iscsi detects it is in crashdump mode. If
be2net was loaded before be2iscsi then this leaves be2net driver hanging on to
resources that the chip stopped recognising after the reset.

This patch replaces  chip reset with Function reset so that only the
particular function and not the whole chip is affected

8fcfb21073 [SCSI] be2iscsi: Fixing the /proc/interrupts problem V3
Fix be2iscsi driver to use a separate pointer for each irq action->name
field and avoid display corruption in /proc/interrupts. The be2iscsi driver
was using a single static array in a function for the irq action->name field.
This results in garbage output from  /proc/interrupts

The pointer for action->name is garbage and scribbles the output on the screen.

This patch fixes the problem:

f457a46f17 [SCSI] iscsi_ibft, be2iscsi, iscsi_boot: fix boot kobj data lifetime management
be2iscsi passes the boot functions its phba object which is
allocated in the shost, but iscsi_ibft passes in a object
allocated for each item to display. The problem is that
iscsi_boot_sysfs was managing the lifetime of the object
passed in and doing a kfree on release. This causes a double
free for be2iscsi which frees the shost in its pci_remove.

This patch fixes the problem by adding a release callback
which the drivers can call kfree or a put() type of function
(needed for be2iscsi which will do a get/put on the shost).

fa95d206e4 [SCSI] be2iscsi: fix disconnection cleanup
This patch fixes 4 bugs in the connection connect/disconnect
cleanup path.

1. If beiscsi_open_conn fails beiscsi_free_ep was always being
called, and if beiscsi_open_conn failed because beiscsi_get_cid
failed then we would free an unallocated cid.

2. If beiscsi_ep_connect failed due to a beiscsi_open_conn failure
it was leaking iscsi_endpoints.

3. beiscsi_ep_disconnect was leaking iscsi_endpoints.
beiscsi_ep_disconnect should free the iscsi_endpoint. We cannot
do it in beiscsi_conn_stop because that is only called for
iscsi connection cleanup. If beiscsi_ep_connect returns
success, but then the poll function fails or the connect
times out then beiscsi_ep_disconnect will be called to clean
up the ep. The conn_stop callout will not be called in that path.

4. beiscsi_conn_stop was freeing the iscsi_endpoint then accessing
it a couple lines later.

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.
