mm: support tlbbatch flush for a range of PTEs

mm: support tlbbatch flush for a range of PTEs

This patch lays the groundwork for supporting batch PTE unmapping in
try_to_unmap_one().  It introduces range handling for TLB batch flushing,
with the range currently set to the size of PAGE_SIZE.

The function __flush_tlb_range_nosync() is architecture-specific and is
only used within arch/arm64.  This function requires the mm structure
instead of the vma structure.  To allow its reuse by
arch_tlbbatch_add_pending(), which operates with mm but not vma, this
patch modifies the argument of __flush_tlb_range_nosync() to take mm as
its parameter.
