[ewg] Building OFED 1.5.4.1 on SLES11SP1 + updates kernel 2.6.32.54-0.3

You probably want to submit on the ewg list and not the rdma list.

On the surface, it looks like OFED would need to differentiate between the 2.6.32.12-0.7 and the new 2.6.32.54-0.3 for at least this issue.

Is the IS_ERR_OR_NULL() a define in the new header file or an inline function?

If it's a define, perhaps an easy test would be to guard the inline in kernel_addons/backport/2.6.32_sles11sp1/include/linux/err.h.

If not, the scope of the change would need to be something like:

1. create new directory kernel_addons/backport/2.6.32_sles11sp1_update with the same files as kernel_addons/backport/2.6.32_sles11sp1
2. Modify the following code fragment in ofed_scripts/get_backport_dir.sh to add another elif test for $minor at 53 and echo 2.6.32_sles11sp1_update
        2.6.32*)
                minor=$(echo $KVERSION | cut -d "." -f 4 | cut -d "-" -f 1)
                if [ $minor -eq 12 ]; then
                        echo 2.6.32_sles11sp1
                else
                        echo 2.6.32
                fi
        ;;
3. Modify err.h to get rid of the duplicate inline of IS_ERR_OR_NULL()
4. See what happens after that...
