On Power ISA the most common page sizes are 4K and 64K. My Raptor Talos II has 64K pages in Fedora.
That said, enough useful "workstation" things assume 4K and break on 64K that I'm hopeful aarch64's use of 16K pages will get people to realize everything doesn't use the same page size. I see transparent hugepages as trying to have your cake and eat it too.

- classichasclass 4y agoFor awhile, Chromium was the biggest offender, and some places may still ship incompatible Electron binaries. I don't use Chrome but I'm told this is now fixed. Hangover also needs 4K, and some kernel modules assume it. Those are all off the top of my head but overall it's starting to get better.
