[v3,0/2] riscv: Support HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC

Message

riscv64 can support sv48 now, so we can add more hugepage-related features
which rely on 3th or 4th level of page table. These two patches will
enable HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC.

v2->v3: Fix the commit log.
v1->v2: Fix the build error reported by kernel-test.

Liu Shixin (2):
  riscv: Enable HAVE_ARCH_HUGE_VMAP for 64BIT
  riscv: Enable HAVE_ARCH_HUGE_VMALLOC for 64BIT
