WangYuli f92ac4ad6c LoongArch: Use __pmd()/__pte() for swap entry conversions 
commit 4a71df151e upstream.

The __pmd() and __pte() helper macros provide the correct initialization
syntax and abstraction for the pmd_t and pte_t types.

Use __pmd() to fix follow warning about __swp_entry_to_pmd() with gcc-15
under specific configs [1] :

        |                ^~~~~~~~~~~~~~~~~~
  cc1: all warnings being treated as errors

Also update __swp_entry_to_pte() to use __pte() for consistency.

README 

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.
