Looking again at this report in more detail, something very strange is going on ...

First, you have MORE free memory than freepages.high. In this case I really don't see why __alloc_pages() wouldn't give the memory to your processes .... > Free swap: 64772
And there is tons of swap free...
Are you absolutely sure this is VM related? This almost looks like the system puts a in a read request but the request queue doesn't get unplugged, or something strange like that ...
There is more than enough memory to satisfy all VM requests and the loop in __alloc_pages() is straightforward enough to give your processes their memory without strange bugs ...
