Update to add clarity and recommendations on running newer kselftests
on older kernels vs. matching the kernel and kselftest revisions.
The recommendation is "Match kernel revision and kselftest."

Changes since v1: Fixed "WARNING: Title underline too short."
Docum
These patches clean up the usage of dynticks nesting counters simplifying the
code, while preserving the usecases.
It is a much needed simplification, makes the code less confusing, and prevents
future bugs such as those that arise from forgetting that the
dynticks_nmi_nesting counter is not a sim
The dynticks_nmi_nesting counter serves 4 purposes:
(a) rcu_is_cpu_rrupt_from_idle() needs to be able to detect first
interrupt nesting level.
(b) We need to detect half-interrupts till we are sure they're not an
issue. However, change the comparison to DYNTICK_IRQ
The dynticks counter are confusing due to crowbar writes of
DYNTICK_IRQ_NONIDLE whose purpose is to detect half-interrupts (i.e. we
see rcu_irq_enter() but not rcu_irq_exit() due to a usermode upcall) and
if so then do a reset of the dyntick_nmi_nesting counters. This patch
tries to get rid of DYNT
