commit 64a2434c9d6bc177df6f20ac42c0fd26fb2ba3b9
Author: Samuel Thibault <address@hidden>
Date:   Mon Oct 31 19:45:30 2016 +0100

    gsync: Fix assertion failure with MACH_LDEBUG
    
    vm_map_lock_read calls check_simple_locks(), so we need to lock hbp
    after taking the vm_map read lock.
    
    * kern/gsync.c (gsync_wait): Call vm_map_lock_read before locking
    &hbp->lock.
    (gsync_wake): Likewise.
