Could you drop "vdso: Reject absolute relocations during build" from the "urgent"
branch for now? It is not necessary for the actual bugfix.
I have an idea on how to fix the issue found by 0day but those patches can then
go through the normal process.

Thanks!

I'd still prefer to delay the other timers/urgent fixes to be on the 
safe side and send them in a day or two, but it's up to Thomas.
