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] :
In file included from ./include/linux/pgtable.h:6,
from ./include/linux/mm.h:31,
from ./include/linux/pagemap.h:8,
from arch/loongarch/mm/init.c:14:
./include/linux/swapops.h: In function ‘swp_entry_to_pmd’:
./arch/loongarch/include/asm/pgtable.h:302:34: error: missing braces around initializer [-Werror=missing-braces]
302 | #define __swp_entry_to_pmd(x) ((pmd_t) { (x).val | _PAGE_HUGE })
| ^
./include/linux/swapops.h:559:16: note: in expansion of macro ‘__swp_entry_to_pmd’
559 | return __swp_entry_to_pmd(arch_entry);
| ^~~~~~~~~~~~~~~~~~
cc1: all warnings being treated as errors
Also update __swp_entry_to_pte() to use __pte() for consistency.

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.
