(*) io_stop_wc();
For memory accesses with write-combining attributes (e.g. those returned
- by ioremap_wc(), the CPU may wait for prior accesses to be merged with
+ by ioremap_wc()), the CPU may wait for prior accesses to be merged with
subsequent ones. io_stop_wc() can be used to prevent the merging of
write-combining memory accesses before this macro with those after it when
such wait has performance implications.
