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

[Colin King]

From: Colin Ian King <colin.k...@canonical.com>

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)
