Regarding the whole series: some of the patches fix actual bugs
(including potential ones), i. e. 1/5 and 4/5, or cleanups (2/5),
which I want to have in the next release. The other ones are new
stuff, which should actually go into "next", but then I don't want to
rip the patch sequence apart.

And we don't have -rc1 yet, so I allow myself to apply the whole
series now.


Applied, thanks.

Best regards,

Wolfgang Denk
