That's far too large for inline.
The reason for it is that it's supposed to minimize the presence of
gadgets that might be used in JOP attacks.

Implementation of write rare for statically allocated data, located in a
specific memory section through the use of the __write_rare label.
The basic functions are wr_memcpy() and wr_memset(): the write rare
counterparts of memcpy() and memset() respectively.
To minimize chances of attacks, this
