A note on testing:

I sadly do not own any Alpha or PowerPC hardware, so when I was testing
these architectures while working on the series, it would be only under
QEMU.

That said, Magnus Lindholm was able to test the series on the Alpha
hardware he owns, see:

Lorenzo Pieralisi did some testing reported outside the mailing list (we
talked on IRC), on the platform he had issues before, and while the issues
were more with procfs races, similar to the sysfs ones this series aims to
fix, he didn't notice regressions when having this series applied.

Thank you!
