Since commit4b63491838("arm64/mm: Close theoretical race where stale TLB entry remains valid"), all arches that use tlbbatch for reclaim (arm64, riscv, x86) implement arch_flush_tlb_batched_pending() with a flush_tlb_mm(). So let's simplify by removing the unnecessary abstraction and doing the flush_tlb_mm() directly in flush_tlb_batched_pending(). This effectively reverts commitdb6c1f6f23("mm/tlbbatch: introduce arch_flush_tlb_batched_pending()").

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.
