PPC has paging modes that require multi-page page tables, and those page tables need to be naturally aligned. The original proposal was to plumb in an @align param to the page allocators[*], but I didn't love the idea of adding another rarely used param to the allocators. v2: - Collect tags. [Itaru, Bibo] - Use 0x180000 as the min GPA for page table pages on LoongArch, instead of changing every other arch to use 0x200000. [Sashiko, Bibo] - Opportunistically move the vGIC LPI stress test's global "gpa_base" variable into setup_memslot().
