Hello,

I would like to know what else is needed to move this patchset forward.
Rafael and Rob have reviewed the DeviceTree bindings. Rafael has reviewed
the relocation of the code that makes use of the mailbox.

Would it be possible for the Hyper-V maintainers to take a look (Michael
Kelley has reviewed the patches already)? Perhaps this could increase the
confidence of the x86 maintainers.

Thanks!

Ricardo
