Subject: fs/proc/task_mmu.c: suppress compilation warnings with W=1
Suppress a bunch of warnings of the form:
fs/proc/task_mmu.c: In function 'show_smap_vma_flags':
fs/proc/task_mmu.c:635:22: warning: initialized field overwritten [-Wt override-init]
[ilog2(VM_READ)] = "rd",
^~~~
fs/proc/task_mmu.c:635:22: note: (near initialization for 'mnemonics[0]')
They happen because of the way we intentionally build the table, so
silence the warning when building with 'make W=1'.
