[ewg] [GIT PULL ofed-1.4 ofed_kernel] - cxgb3 backports for ofed-1.4

[Steve Wise]

Vlad,

Please pull from:

git://git.openfabrics.org/~swise/ofed-1.4.git ofed_kernel

There are 20 commits that add the backports for cxgb3, one for each 
kernerl.  They also create new include files in kernel_addons/backports 
to provide backports for net_namespace and a few other needed functions. 
This results in removing 4 kernel_patches/backports/* files for the 
core, iw_cxgb3, and rds modules.  Namely these patches are no longer 
needed and are removed:

cma_to_2_6_24.patch
addr_to_2_6_24.patch
iwch_cm_to_2_6_24.patch
rds_to_2_6_24.patch

New kernel_addon/backports/* changes:

- add net_namespace.h so modules that include it won't break
- add backport macro to remove the net namespace parameter from:
    - ip_dev_find()
    - route_ouput_flow() and route_output_key()
    - dev_get_by_name()
- add is_vmalloc_addr() backport function
- add vlan_dev_info() backport function

I built these against a handful of the backport kernels.  I didn't do 
the cross platforms builds.  So please lemme know if anything still 
breaks in the cxgb3 code.

Thanks,


Steve.
