Subject: [PATCH 3/5] x86: early_ioremap_reset fix 2
Date: Thu, 31 Jan 2008 15:36:04 +0800 [thread overview]
Message-ID: <1201764964.12950.24.camel@caritas-dev.intel.com> (raw)
This patch fixes a bug of early_ioremap_reset(), which had been fixed
before by "convert the boot time page table to the kernels native
format" patch. But that patch has been reverted now.
Signed-off-by: Huang Ying <ying.huang@intel.com>
