[PATCH 12/23] powerpc/mm: Declare some prototypes

[Cédric Le Goater]

It fixes this W=1 compile error :

../arch/powerpc/mm/book3s64/hash_utils.c:1515:5: error: no previous prototype for ‘__hash_page’ [-Werror=missing-prototypes]
 1515 | int __hash_page(unsigned long trap, unsigned long ea, unsigned long dsisr,
      |     ^~~~~~~~~~~
../arch/powerpc/mm/book3s64/hash_utils.c:1850:6: error: no previous prototype for ‘low_hash_fault’ [-Werror=missing-prototypes]
 1850 | void low_hash_fault(struct pt_regs *regs, unsigned long address, int rc)
      |      ^~~~~~~~~~~~~~
