Barry Song 2f4ab3ac10 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.

README

Linux kernel

There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

In order to build the documentation, use make htmldocs or make pdfdocs. The formatted documentation can also be read online at:

https://www.kernel.org/doc/html/latest/

There are various text files in the Documentation/ subdirectory, several of them using the reStructuredText markup notation.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
