[ewg] Compile error on 7/14 daily build of OFED-1.5

[Jack Morgenstein]

Culprit is  /var/tmp/OFED_topdir/BUILD/ofa_kernel-1.5/kernel_addons/backport/2.6.18-EL5.3/include/linux/log2.h
This file assumed that there was no native include/linux/log2.h -- which is incorrect in RHEL5.2 and 5.3

I'll fix now.  Vlad should be taking this commit (from my clone) on Sunday.

If you want to try the fix, you can simply copy over file
   kernel_addons/backports/2.6.21/include/linux/log2.h
to:
   kernel_addons/backports/2.6.18-EL5.3/include/linux/log2.h

(and also to 
   kernel_addons/backports/2.6.18-EL5.2/include/linux/log2.h
 if you are also using RHEL5.2)

Then try compiling.
Please let me know the result.
