318c4f97e6 CALLOUT_MPSAFE has lost its meaning since r141428, i.e., for more than ten 
years for head.  However, it is continuously misused as the mpsafe argument
for callout_init(9).  Deprecate the flag and clean up callout_init() calls
to make them more consistent.

0e8f15c195 Do not mark shared structures as __packed, it leads to race condition 
If structure packed as __packed clang (and probably gcc) generates
code that loads word fields (e.g. tx_pos)  byte-by-byte and if it's
modified by VideoCore in the same time as ARM loads the value result
is going to be mixed combination of bytes from previous value and
new one.
