This patch reserves the EFI memory map with reserve_early(). Because EFI memory map is allocated by bootloader, if it is not reserved by reserved_early(), it may be overwritten through address returned by find_e820_area().

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: NHuang Ying <ying.huang@intel.com> Cc: andi@firstfloor.org Cc: mingo@redhat.com Signed-off-by: NThomas Gleixner <tglx@linutronix.de>

when 1/3 user/kernel split is used, and less memory is installed, or if we have a big hole below 4g, max_low_pfn is still using 3g-128m try to go down from max_low_pfn until we get it. otherwise will panic. need to make 32-bit code to use register_e820_active_regions ... later.

on 32-bit in head_32.S after initial page table is done, we get initial max_pfn_mapped, and then kernel_physical_mapping_init will give us a final one. We need to use that to make sure find_e820_area will get valid addresses for boot_map and for NODE_DATA(0) on numa32. XEN PV and lguest may need to assign max_pfn_mapped too.

make mptable to be consistent with acpi routing, so we could: 1. kexec kernel with acpi=off 2. work around BIOSes where acpi routing is working, but mptable is not right, so can use kernel/kexec to start other OSes that don't have good acpi support. command line: update_mptable Signed-off-by: NYinghai Lu <yhlu.kernel@gmail.com> Signed-off-by: NIngo Molnar <mingo@elte.hu>

we don't need to call memory_present that early. numa and sparse will call memory_present later and might even fail, it will call memory_present for the full range. also for sparse it will call alloc_bootmem ... before we set up bootmem.

so every element will represent 64M instead of 256M. AMD opteron could have HW memory hole remapping, so could have [0, 8g + 64M) on node0. Reduce element size to 64M to keep that on node 0 Later we need to use find_e820_area() to allocate memory_node_map like on 64-bit. But need to move memory_present out of populate_mem_map...

Sitsofe Wheeler reported boot problems on linux-next. It looks like the same issue as found by Soeren Sandman in 7575217f656a93, "x86: initialize all fields of mp_irqs[mp_irq_entries]". But his fix is also not complete, as dstapic is used before it assigned.
