I've finally managed to debug this (by dumping used /sys/ files from
an affected system in Fedora build system, replacing /sys/ with /tmp/
in gcc sources and populating there those files), I think following patch
ought to fix it.
I'll test it tonight in my bootstrap/regtest (but that's a non-numa box),
can somebody with a box where places-10.c fails reliably test this too?

Thanks.
