Subject: x86, kexec: Set ident mapping for kernel that is above max_pfn
X-Git-Tag: v3.9-rc1~105^2~25

x86, kexec: Set ident mapping for kernel that is above max_pfn

When first kernel is booted with memmap= or mem=  to limit max_pfn.
kexec can load second kernel above that max_pfn.

We need to set ident mapping for whole image in this case instead of just
for first 2M.
