[PATCH v3 0/3] RISC-V KVM gstage page table dumper

This series adds support for dumping RISC-V KVM gstage (second-stage)
page tables via debugfs, allowing inspection of the guest physical
address translation setup.

Changes since v2:
- Split the first patch into two as requested by Paul Walmsley:
  Patch 1 now only creates ptdump.h and moves declarations there
  with no functional changes (structures moved verbatim).
  Patch 2 handles the structure renames and per-level attribute
  bit parsing logic.

Patch 1: Create ptdump.h and move declarations
Patch 2: Use per-level attribute bits for parsing
Patch 3: Register gstage ptdump with debugfs on guest creation

Dylan.Wu (3):
  riscv: ptdump: Create ptdump.h and move declarations
  riscv: ptdump: Use per-level attribute bits for parsing
  KVM: riscv: Register ptdump with debugfs on guest creation
