request_phb_iospace() can be called from different CPUs at init time (at least with my next patch) and thus needs a spinlock. As for the next patch, this is a temporary workaround for 2.6.22 issues until my rewrite of IO mappings is ready (for 2.6.23) Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
