Subject: mips: fix compilation error
Date: Mon, 25 Aug 2025 23:42:45 +0200

The following build error occurs on a mips build configuration
(32r2el_defconfig and similar ones)
./arch/mips/include/asm/cacheflush.h:42:34: error: passing argument 2 of `set_bit'
from incompatible pointer type [-Werror=incompatible-pointer-types]
   42 |         set_bit(PG_dcache_dirty, &(folio)->flags)
      |                                  ^~~~~~~~~~~~~~~
      |                                  |
      |                                  memdesc_flags_t *

This is due to changes introduced by
commit 30f45bf18d55 ("mm: introduce memdesc_flags_t"), which did not update
these usage sites.
