Highmem is not very stable currently, we will meet the Bus Error bug when building kernel package on ES2.0. This patch is a workaround, which let us to use full of 1G memory but size of highmem is 0K with 2G:2G split. It's quite stable because highmem is not active. When we find the root cause and final fixing, we can switch back to 3G:1G normal split config.
