Subject: [PATCH v2 0/2] riscv: Support HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC

Since riscv64 has already support SATP_MODE_57 by default, it is time to
support more hugepage-related features. These two patches will enable
HAVE_ARCH_HUGE_VMAP and HAVE_ARCH_HUGE_VMALLOC.

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
