The AltiVec header file breaks boolean type. [1] [2]
Currently the workaround was located only in mlx5 device.
Adding the trace module caused this issue to appear again, due to
order of includes, it keeps overriding the local fix.
This patch solves this issue by resetting the bool type, immediately
after it is being changed.

stringop-overflow warns when it sees a possible overflow
in a string operation.
In the rte_memcpy functions different branches are taken
depending on the size. stringop-overflow is raised for the
branches in the function where it sees the static size of the
src could be overflowed.
However, in reality a correct size argument and in some cases
dynamic allocation would ensure that this does not happen.
For example, in the case below for key, the correct path will be
chosen in rte_memcpy_generic at runtime based on the size argument
but as some paths in the function could lead to a cast to 32 bytes
a warning is raised.

These APIs enables graph framework operations such as create, lookup,

edge update, and edge shrink, etc. The API also allows creating the
stats cluster to monitor per graph and per node stats.

Currently, even though memory is mapped with PROT_NONE, this does not
cause it to be excluded from core dumps. This is counter-productive,
because in a lot of cases, this memory will go unused (e.g. when the

pages into it).
