Use results of make namespacecheck to make functions local and
remove code that is not used.

Also rename initialize_ethtool_ops to vxge_initialize_ethtool_ops.

Compile tested only.

cb27ec6064 vxge: Pass correct number of VFs value to pci_sriov_enable().
-  max_config_dev loadable parameter is set to 0xFF by default. Pass correct
   number of VFs value to pci_sriov_enable() if max_config_dev is set to its 
   default value.

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.

fa41fd1003 vxge: Check if FCS stripping is disabled by the firmware.
- Added a function to check if FCS stripping is disabled by the firmware, if
  it is not disabled fail driver load.

- By default FCS stripping is disabled by the firmware. With this assumption
  driver decrements the indicated packet length by 4 bytes(FCS length).

- This patch ensures that FCS stripping is disabled during driver load time.

ff67df55f6 vxge: fix pktgen hangs (don't abuse skb->cb[])
This patch fixes a case in the transmit completion code which was resulting
in pktgen hanging at the end of a run.  The cause is due to the fact that
the ->cb[] area of an skb cannot be used in a network driver's transmit
path, as that area belongs to the network protocol.  Pktgen hangs, as it
sends out the same packet multiple times, and vxge's use of this area of
the skb for a temporary list can only add the packet to the temporary list
once (while it may be on the queue many times).  The fix is to remove this
abuse of skb->cb[].  Instead, skb pointers are placed into a temporary
stack array, and then free outside of the tx lock.  This retains the smp
optimization of doing dev_kfree_skb() outside of the tx lock.

40a3a9156d Neterion: New driver: Hardware init & configuration
This patch takes care of Initialization and configuration steps of
Neterion Inc's X3100 Series 10GbE PCIe I/O Virtualized Server Adapter.
- Device Initialization.
- Verification and setting of device config parameters.
- Allocation of Tx FIFO and Rx Ring descriptors (DTR).
- APIs to get various type of hw stats
- APIs to configure RTS (Receive Traffic Steering)

- Changes in this submission -
        - Include vmalloc header without which a compilation error occured
          on sparc64, ppc64 and IA64 plaforms.
	- Fixed compilation warning in register_poll, write32_upper,
          write32_lower and the special write64 functions on ppc64.
        - General cleanup - removed redundant includes and defines.

- Changes in previous submissions -
        - Add readq/writeq implementation for the driver for 32 bit systems -
          reported by Dave Miller.
- Incorporated following comments from Ben Hutchings
        - Start a comment with "/**" to make it a kernel-doc comment.
        - Use prefix, "__vxge" in front of hw functions to make them globally
          unique.
        - Fixed unnecessary clearing members of *channel just before freeing
        - Use backslashes only for macro definitions and not in multi-line
          statements.
        - Used pci_find_capability instead of redefining it.
        - Used device and revision ids that are already in pdev - no need to
          read them again.
        - Used pci_save_state() and pci_restore_state() around resets.
        - Used udelay and mdelay directly instead of wrapper.
        - In __vxge_hw_device_register_poll() reset i to 0 after the
          microsecond delay loop to commence the millisecond delay loop.
        - Corrected spelling "sapper" - should be "swapper"
        - Remove too much vertical whitespace.
        - Replaced magic numbers with appropriate macros
- Incorporated following comments from Andi Kleen [andi@firstfloor.org]
        - Reduced the arguments in functions or refactored them into smaller
        functions.
        - Allocate page sized memories used in slow path with vmalloc.
        - Use asserts where necessary.
        - Use macros instead of magic numbers.
        - Use the pci layer code instead of defining own functions
        - Remove driver wrappers such as xge_hw_device_private_set().
        - Fixed sparse warnings.
