Subject: [PATCH 0/3] Add support for free vmemmap pages of HugeTLB for arm64

This patchset is based on the series of "Free some vmemmap pages of HugeTLB
page". More details can refer to the below link.

I often received some feedback (We want to test this feature on arm64) before.
Because the previous code has been reviewed for 18 versions and is merged
into mm tree, I think that it is time to release this patchset. If you want
to test then you can start now :-). And I also hope someone can review this.

Thanks.
