[PATCH] mm/shmem.c: make array 'values' static const, makes object smaller

[Colin King <colin.king@xxxxxxxxxxxxx>]

From: Colin Ian King <colin.king@xxxxxxxxxxxxx>

Don't populate the array 'values' on the stack but instead make it
static const. Makes the object code smaller by 111 bytes.

Before:
   text	   data	    bss	    dec	    hex	filename
 108612	  11169	    512	 120293	  1d5e5	mm/shmem.o

After:
   text	   data	    bss	    dec	    hex	filename
 108437	  11233	    512	 120182	  1d576	mm/shmem.o

(gcc version 9.2.1, amd64)
