[PATCH 0/2] docs: Remove the unsupported preempt= modes

[Jinjie Ruan]

The none and voluntary preemption models can no longer be selected with
CONFIG_PREEMPT_DYNAMIC:

- commit 7dadeaa6e851 ("sched: Further restrict the preemption modes")
  stopped PREEMPT_NONE and PREEMPT_VOLUNTARY from being offered on
  architectures that select ARCH_HAS_PREEMPT_LAZY;

- commit d3d16750693b ("sched: dynamic: Make PREEMPT_DYNAMIC depend on
  ARCH_HAS_PREEMPT_LAZY") made that dependency official and removed the
  code that parsed "preempt=none" and "preempt=voluntary".

Two documentation files still describe both as runtime options. The first
patch drops them from the preempt= entry in kernel-parameters.txt, the
second fixes the model table in sched-preemption.rst, which also misstates
why an architecture may or may not offer them.

Nothing in the code changes.
