Pasi,

I understand it, but i cannot rebuild Andy's patch set.
I am not aware of  what the procedure is, but suspect it's not
too much complicated.
If commit was mentioned, it says to me only that some Git Repo is a source.
Nothing else. If you can , please , do it.

Boris

Boris: Just generate a new (additional) patch that fixes the problem with
CONFIG_SPARSE_IRQ. Much easier for other people to apply it then, and get it
right.. also no need to explain many times what to change and where..
