r150008 is required to fix missing symbols in the WebKitPluginProcess that's built from the webkit-2.0 branch. A modified patch of that revision is required as there for instance is no libPlatform.la or libANGLE.la in the stable branch.

Based off r150008, the patch only applies to the webkit-2.0 branch.
r150884 and r151492 should also be applied afterwards and will be added to the wiki page as proposed merges.
