Date: Tue, 03 Mar 2009 12:55:05 +0200 From: Pekka Enberg <penberg@...helsinki.fi> To: mingo@...e.hu Cc: x86@...nel.org, linux-kernel@...r.kernel.org Subject: [PATCH 2/2] x86: use roundup() instead of PAGE_ALIGN() in find_early_table_space() From: Pekka Enberg <penberg@...helsinki.fi> Impact: cleanup This patch changes find_early_table_space() to use roundup() for rounding up tables to page size to unify the common parts of the 32-bit and 64-bit implementations.
