[ Upstream commit 12c16919652b5873f524c8b361336ecfa5ce5e6b ] When building the mm tests with a riscv32 compiler, we see a range of shift-count-overflow errors from shifting 1UL by more than 32 bits in do_mmaps(). Since, the relevant code is only called from code that is gated by `__riscv_xlen == 64`, we can just apply the same gating to do_mmaps().

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.
