Subject: VDSO and dcache aliasing

Hello James,

A year ago, you wrote that patch:

https://www.linux-mips.org/archives/linux-mips/2017-06/msg00658.html

You called it a hack but it has been used since then. As you will
certainly realize by now, Ocelot is one of the affected SoC so we would
pretty much like to see this going upstream.

What would be the way forward?

Regards,
