Since you're going to update this, please fix the typos in the above,
e.g., s/Documetation/Documentation/.
In addition, please run "git log --oneline" on the files you're
changing and make your subject lines consistent in style and
capitalization with previous ones, e.g., use "PCIe" consistently.
"Modify the ..." contains no useful information. Of course a patch
modifies something -- please tell us what the modification is useful
for.
