Huang Ying 5359454701 x86, kexec: x86_64: add identity map for pages at image->start
Impact: Fix corner case that cannot yet occur

image->start may be outside of 0 ~ max_pfn, for example when jumping
back to original kernel from kexeced kenrel. This patch add identity
map for pages at image->start.
