OF: Fixup resursive locking code paths · 925df9b3

Thomas Gleixner authored Aug 13, 2009

The conversion of devtree_lock from rwlock to spinlock unearthed
recursive locking pathes. Instead of going down the hassle of having
an atomic_rwlock implementation fixup the code pathes to avoid the
recursive locking.

powerpc: OF convert to atomic lock · 5b659531

Thomas Gleixner authored Jul 29, 2009

Replaced the RW lock for now with atomic_spinlock. We have no
atomic_rwlocks in -rt right now and I doubt that the OF path is
performance critical.
