[PATCH -mm 1/2 -v2] kexec/i386: kexec page table code clean up - add arch_kimage

This patch add an architecture specific struct arch_kimage into struct kimage. Three pointers to page table pages used by kexec are added to struct arch_kimage. The page tables pages are dynamically allocated in machine_kexec_prepare instead of statically from BSS segment. This will save up to 20k
