Thank you. I'm also attaching our findings regarding mTHP allocation &
reclamation fallback, along with our approach and observations on running
TAO on Pixel 6.

From deploying mTHP on numerous phones, I've learned that I'm not keen
on using dedicated page blocks for mTHP. Instead, I prefer the virtual zone
approach due to the folio size conflict in a single LRU. Further details are
available in the attached PDF.

Best regards
