x86: move reserve_setup_data to setup.c
Ying Huang would like setup_data to be reserved, but not included in the no save range. Here we try to modify the e820 table to reserve that range early. also add that in early_res in case bootloader messes up with the ramdisk. other solution would be 1. add early_res_to_highmem... 2. early_res_to_e820... but they could reserve another type memory wrongly, if early_res has some resource reserved early, and not needed later, but it is not removed from early_res in time. Like the RAMDISK (already handled). Signed-off-by: Yinghai Lu <yhlu.kernel@gmail.com> Cc: andi@firstfloor.org Tested-by: Huang, Ying <ying.huang@intel.com> Signed-off-by: Ingo Molnar <mingo@elte.hu>
