Issues with RaspberryPi 3 aarch64 kernel config page size

[mmozeiko]

Hi.

I've noticed that rpi3 AArch64 image has kernel configured with 64k page size. Why is that instead of default 4k page size?
By not using 4k page size it prevents to use F2FS filesystem. F2FS requires 4k page size. I think on devices like rpi3 using f2fs filesystem would be better choice because typically / partition is located on sdcard. But now this is requires custom kernel.

Would it be possible to change this, switch to 4k page size?
