From 87655ff26817993932b7d049c4df226fb2c0ac5f Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Thu, 10 Nov 2005 14:53:16 +1100 Subject: [PATCH] powerpc: 64k pages pmd alloc fix This patch makes the kernel use a different kmem cache for PMD pages as they are smaller than PTE pages. Avoids waste of memory.
