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.

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

Hey Liu Shixin,
As I'm sure you saw earlier today LKP randconfig testing of linux-next*
found a problem with your patchset, but looks like it should be
trivially fixable.

Thanks,
Conor.

* I accidentally added it to my dt-for-next branch, from which it is now
dropped.
