commit 2f5be6db29c87967e2b443d0c4757ff8132d56d5
Author: Florian Weimer <fweimer@redhat.com>

    nptl: Move __pthread_cleanup_upto into libc
    
    This internal symbol is used as part of the longjmp implementation.
    Rename the file from nptl/pt-cleanup.c to nptl/pthread_cleanup_upto.c
    so that the pt-* files remain restricted to libpthread.
