Hi Arnd,

It doesn't look like anyone is pouncing on the syscall number in linux-
next currently. It might be nice to have this patch go through linux-
next since it touches so many architectures. And it sounds like x86
folk are ok with this, so if you could pick it up for 6.7 that would be
great. Thanks!
