In verifier.rst, there is a typo in section 'Register parentage chains'.
Caller saved registers are r0-r5, callee saved registers are r6-r9.
Here by context it means callee saved registers rather than caller saved
registers. This may confuse users.

In verifier.rst, I found an incorrect statement (maybe a typo) in section
'Liveness marks tracking'. Basically, the wrong register is attributed
to have a read mark. This may confuse the user.

filter.rst starts out documenting the classic BPF and then spills into
introducing and documentating eBPF. Move the eBPF documentation into
rwo new files under Documentation/bpf/ for the instruction set and
the verifier and link to the BPF documentation from filter.rst.
