When support page mapping percpu first chunk allocator on arm64, we
found there are lots of duplicated codes in percpu embed/page first
chunk allocator. This patchset is aimed to cleanup them and should
no funciton change, only test on arm64.

Hi Kefang,

I apologize for the delay. It's a holiday week in the US + I had some

Thanks,
Dennis
