Attempt VMA lock-based page fault handling first, and fall back to the existing mmap_lock-based handling if that fails. The "ebizzy -mTRp" test on Loongson-3A6000 shows that PER_VMA_LOCK can improve the benchmark by about 17.9% (97837.7 to 115430.8). This is the LoongArch variant of "x86/mm: try VMA lock-based page fault handling first".

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.
