Subject: [PATCH 1/4] regex/mlx5: fix size of setup constants
The constant representing the size of the metadata is defined as a unsigned
int variable with 32-bit.
Similarly the constant representing the maximal output is also defined as a
unsigned int variable with 32-bit.
There is potentially overflowing expression when those constants are
evaluated using 32-bit arithmetic, and then used in a context that expects an
expression of type size_t (64 bits, unsigned).
Change the size of the above constants to 64-bit.
