This patchset is for adding efi runtime support on kexec kernel
kernel patches see below thread:
http://thread.gmane.org/gmane.linux.kernel.efi/2491

in kexec-tools, this patchset will do below:
1. retrieve efi_info from debugfs boot_params, and fill the
x86 setup header

2. collect data efi runtime needed:
/sys/firmware/efi/systab: fw_vendor, runtime, config_tables and smbios
/sys/firmware/efi/efi-runtime-map/*, the phys-virt mappings in 1st kernel

3. assemble setup_data based on data get in 2) then pass it to 2nd kernel

changelog v3->v4:
update efi_info memmap to the saved runtime map instead of use 1st kernel
untouched memmap.

Tested on OVMF, dell laptop, lenovo laptop and HP workstation
