- update documentation for sysfs, proc, livepatch

Also we should publish somewhere the information about TIF_KLP_NEED_UPDATE
flag, e.g. /proc/<pid>/klp_need_update. It is handy to see what
process blocks the transition. We have something similar in
kGraft, see in_progress_show() at
https://git.kernel.org/cgit/linux/kernel/git/jirislaby/kgraft.git/commit/?h=kgraft-4.4&id=1c82fbd7b1fe240f4ed178a6506a93033f6a4bed

Patch 13/14 exposes the per-task patched state in /proc, so I think that
already does what you're asking for?  It doesn't expose
TIF_KLP_NEED_UPDATE, but that's more of an internal detail I think.

Heh, I have missed it. Yup, the per-thread patch state info seems to
be enough.
