Linux 5.6 rc7

The world around us may be going through strange times, but at least
so far kernel development looks normal.

The bulk this week is - as usual - drivers: gpu, mmc, staging, iio,
usb, sound... But there's some VM fixes, some arch updates,
documentation and tooling (mostly turbostat).

Nothing really stands out, it's all pretty small. I'm going to be
optimistic, and say that it's because we're nicely on track for a
normal calm release, but obviously it may be partly because everybody
is distracted by virus worries. But I haven't seen anything that looks
hugely worrisome on the kernel side.
