</div>Hi !<br>
<br>
The patchwork link unfortunately didn't survive the transition to<br>
patchwork 2.<br>
<br>
Do you know what's the status of Hugetlb support for 44x ? Is there any<br>
plan to release that for upstream inclusion ?<br>
<br>
Cheers,<br>
Ben.<br>

<br>I didn't follow up after this to get it merged upstream. Also I don't know if hugetlb core has changed to deal with PTEs in high memory.<br><br>./satya<br>
