This is too generic a name. How about something like

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
