Qt WebKit qml will crash upon startup on ARM

When starting a qml WebView i get the following error message

ASSERTION FAILED: isPointerTypeAlignmentOkay(reinterpret_cast<TypePtr>(ptr))
../WTF/wtf/StdLibExtras.h(95) : TypePtr reinterpret_cast_ptr(void*) [with TypePtr = long long unsigned int*]

After investigating it, that following patch fixed the issue. its is an upstream webkit patch that was not merged obviously :
