It's defined in asm-<arch>/segment.h. On i386, it's a macro which
is defined as:
#define memcpy_tofs(to, from, n) \
(__builtin_constant_p(n) ? \
__constant_memcpy_tofs((to),(from),(n)) : \
__generic_memcpy_tofs((to),(from),(n)))
Both of these functions are also defined in asm-i386.h, as inline
functions.
Basically it copies some data from kernel memory to process memory
(which is referenced via the `fs' segment register).

Internal kernel functions don't have manpages.
