Subject: [PATCH 2/2] x86: use roundup() instead of PAGE_ALIGN() in find_early_table_space()
Date: Tue, 03 Mar 2009 12:55:05 +0200 [thread overview]
Message-ID: <1236077705.2675.6.camel@penberg-laptop> (raw)
From: Pekka Enberg <penberg@cs.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.
