History
Andreas Kling dce030eefc Kernel: Use RDTSC instead of get_fast_random() for syscall stack noise 
This was the original approach before we switched to get_fast_random()
which wasn't fast enough, so we added a buffer.

Unfortunately that buffer is racy and we can actually skid past the end
of it and continue fetching "random" offsets from the adjacent memory
for a while, until we run out of kernel data segment and trip a fault.

Instead of making this even more convoluted, let's just go back to the
pleasantly simple (RDTSC & 0xff) approach. :^)

Fixes #4912.
