[PATCH] powerpc: Fix a huge page bug
The 64k pages patch changed the meaning of one argument passed to the low level hash functions (from "large" it became "psize" or page size index), but one of the call sites wasn't properly updated, causing potential random weird problems with huge pages. This fixes it. Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Signed-off-by: Paul Mackerras <paulus@samba.org>
