From: Pekka Enberg Date: Tue, 3 Mar 2009 10:55:05 +0000 (+0200) Subject: x86: use roundup() instead of PAGE_ALIGN() in find_early_table_space() X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=fd578f9c0a0a7bf3e460e6f21cdc6f4018949e80;p=deliverable%2Flinux.git x86: use roundup() instead of PAGE_ALIGN() in find_early_table_space() 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.
