Public bug reported:
[ Impact ]
* TD with large profiles (e.g. 128 vcpu && 512GB RAM) fail to boot.
[ Fix ]
* Clean cherry-pick from intel-kernel:
a7b7338a90c1 mm/page_alloc: Fix memory accept before watermarks gets initialized
a11a86c9ac1d mm: accept to promo watermark
ce0381880b6c mm: create promo_wmark_pages and clean up open-coded sites
86cae05a0654 mm: print the promo watermark in zoneinfo
Those are submitted upstream.
[ Test Plan ]
* Was tested by intel (branch v6.8-tdx) on failing configuration.
[ Where problems could occur ]
* Memory allocation issue.
[ Other Info ]
* This fix is submitted for noble:linux-intel in order to have more exposure
and wait for upstream feedback before submitting it for noble:linux.
