Alexandre Ghiti 7e3811521d riscv: Implement flush_cache_vmap() 
The RISC-V kernel needs a sfence.vma after a page table modification: we
used to rely on the vmalloc fault handling to emit an sfence.vma, but
commit 7d3332be01 ("riscv: mm: Pre-allocate PGD entries for
vmalloc/modules area") got rid of this path for 64-bit kernels, so now we
need to explicitly emit a sfence.vma in flush_cache_vmap().

Note that we don't need to implement flush_cache_vunmap() as the generic
code should emit a flush tlb after unmapping a vmalloc region.

Fixes: 7d3332be01 ("riscv: mm: Pre-allocate PGD entries for vmalloc/modules area")
