Heh. I noticed this only now.  No, this is not the commit which introduced
the breakage.  It is either

commit 56a3c24ffc11955ddc7bb21362ca8069a3fc8c55
Author: Stefan Berger <stefanb@linux.vnet.ibm.com>

    tpm: Probe for connected TPM 1.2 or TPM 2

which introduced select() in the first place (provided similar select()
hasn't been used in there before.  Or some other commit somewhere else
which allowed to have large number of filedescriptors - provided it wasn't
possible before.  But definitely not a commit which just moved file into
another subdir :)
