This patchset fixes two bugs in the riscv64 architecture support of makedumpfile related to virtual-to-physical address translation.
Patch 1 fixes vaddr_to_paddr_riscv64() to exclude vmalloc and vmemmap regions from the VTOP() fast path. These regions are not linearly mapped and must go through page table walk. Patch 2 fixes vtop_riscv64() to correctly handle huge pages when _PAGE_LEAF is set at PGD/P4D/PUD/PMD level. The original code incorrectly fell through to the next level, causing wrong physical address computation.
