Subject: [PATCH v1 0/2] cleanup.h: Introduce DEFINE_INACTIVE_GUARD()/activate_guard()

In preparation to introduce a "DEFINE_INACTIVE_GUARD()" to actually
define a guard variable, rename all the guard "DEFINE_" prefix to
"DECLARE_".

To cover scenarios where the scope of the guard differs from the scope
of its activation, introduce DEFINE_INACTIVE_GUARD() and activate_guard().

The faultable tracepoints depend on this.

Based on v6.11-rc5.

Thanks,

Mathieu
