This patch does some preparation works to extend batched TLB flush to arm64. Including: - Extend set_tlb_ubc_flush_pending() and arch_tlbbatch_add_mm() to accept an additional argument for address, architectures like arm64 may need this for tlbi. - Rename arch_tlbbatch_add_mm() to arch_tlbbatch_add_pending() to match its current function since we don't need to handle mm on architectures like arm64 and add_mm is not proper, add_pending will make sense to both as on x86 we're pending the TLB flush operations while on arm64 we're pending the synchronize operations. This intends no functional changes on x86.

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 Restructured Text 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.
