x86: Fix size for ex trampoline with 32bit
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 Signed-off-by: Yinghai Lu <yinghai@kernel.org> LKML-Reference: <1261525263-13763-2-git-send-email-yinghai@kernel.org> Signed-off-by: H.
