Subject: [PATCH 01/29] x86: fix size for ex trampoline with 32bit
Date: Sun, 03 Jan 2010 19:04:39 -0800	[thread overview]
Message-ID: <1262574307-17040-2-git-send-email-yinghai@kernel.org> (raw)
In-Reply-To: <1262574307-17040-1-git-send-email-yinghai@kernel.org>

fix for error that is introduced by
| x86: Use find_e820() instead of hard coded trampoline address

it should end with PAGE_SIZE + PAGE_SIZE
