[PATCH 1/2] riscv: ptdump: Move pagetable definitions to common header

[Dylan.Wu]

Hi Paul,

Thank you very much for taking the time to review this patch and for
the helpful suggestion.

I have split the patch as you requested and sent v2:

  https://lore.kernel.org/linux-riscv/20260727122745.118764-1-fredwudi0305@gmail.com/

Changes in v2:
  - Patch 1/3: Create ptdump.h, move declarations there, and export note_page()
  - Patch 2/3: Make attribute parsing use per-level bits, rename
               pg_level[] to kernel_pg_levels[]
  - Patch 3/3: KVM gstage ptdump

I would greatly appreciate any further feedback you may have.

Best regards,
Dylan
