[ Upstream commit a74f038fa50e0d33b740f44f862fe856f16de6a8 ] The pt_dump_seq_puts() macro incorrectly uses seq_printf() instead of seq_puts(). This is both a performance issue and conceptually wrong, as the macro name suggests plain string output (puts) but the implementation uses formatted output (printf). The macro is used in ptdump.c:301 to output a newline character. Using seq_printf() adds unnecessary overhead for format string parsing when outputting this constant string. This bug was introduced in commit59c4da8640("riscv: Add support to dump the kernel page tables") in 2020, which copied the implementation pattern from other architectures that had the same bug.

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.
