x86: reserve highmem pages via reserve_early
This patch makes early reserved highmem pages become reserved pages. This can be used for highmem pages allocated by bootloader such as EFI memory map, linked list of setup_data, etc. Signed-off-by: Huang Ying <ying.huang@intel.com> Cc: andi@firstfloor.org Cc: mingo@redhat.com Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
