x86, realmode: Separate real_mode reserve and setup
After we switch to use #PF handler help to set page table, init_level4_pgt will only have entries set after init_mem_mapping(). We need to move copying init_level4_pgt to trampoline_pgd after that. So split reserve and setup, and move the setup after init_mem_mapping() Signed-off-by: Yinghai Lu <yinghai@kernel.org> Link: http://lkml.kernel.org/r/1359058816-7615-11-git-send-email-yinghai@kernel.org Cc: Jarkko Sakkinen <jarkko.sakkinen@intel.com> Acked-by: Jarkko Sakkinen <jarkko.sakkinen@intel.com> Signed-off-by: H.
