The commit 04ae87a52074 ("ftrace: Rework event_create_dir()") restructured
various macros in the ftrace framework. These changes also had the nice
side effect that the linux/types.h include is no longer necessary to define
some of the types used by these macros.

The Linux Kernel 3.16 reached its end of life [1] after 6 years. Instead it
is recommended to use at least kernel 4.4. It is also already over 4 years
old but still maintained by the stable kernel team. All older kernels
(v3.16 - v4.3) should therefore be dropped to reduce the support overhead.
The kernel provides a function to create random values from 0 - (max-1)
since commit f337db64af05 ("random32: add prandom_u32_max and convert open
coded users"). Simply use this function to replace code sections which use
prandom_u32 and a handcrafted method to map it to the correct range.
