Ralf Baechle 1186e4e904 MIPS: Avoid overoptimization by GCC. 
Without this, it's possible that LTO will discard the calls to
set_except_vector() in the probe for the DADDI overflow bug resulting in a
kernel crash like this:

 [...]
 Mount-cache hash table entries: 256
 Checking for the daddi bug... Integer overflow[#1]:
 Cpu 0
 $ 0   : 0000000000000000 0000000010008ce1 0000000000000001 0000000000000000
 $ 4   : 7fffffffffffedcd ffffffff81410000 0000000000000030 000000000000003f
 [...]

There are other similar places in the kernel so we've just been lucky
that GCC's been tolerant.
