I didn’t try FLATMEM. Thanks for advising, I enabled FLATMEM for ARM64 and am
able to save ~14M. Will post a new patch for Kconfig changes.
Thanks,

This patch adds support for 43bit physical address. Additionally,
this patch adds support for 27bit section size. This is useful in
reducing kernel memory usage. One usecase is in kdump kernel.
