Hi Nick,

This series is intended to go into v5.10 so rebasing it against -next
defeats that; please test it against v5.10-rc4, where it still applies
cleanly. The conflicts will be handled by other entities (Stephen Rothwell
and Linus).

If you want to test it against -next, 'git am -3' will allow you to
easily handle the conflict.

Cheers,
Nathan
