Subject: [PATCH] tracing: Fix TRACING_SUPPORT dependency
commit 40ada30f9621fbd831ac2437b9a2a399aad34b00 ("tracing: clean up
menu"), despite the "clean up" in its purpose, introduced behavioural
change for Kconfig symbols: we no longer able to select tracing
support on PPC32 (because IRQFLAGS_SUPPORT isn't yet implemented).
The IRQFLAGS_SUPPORT is not mandatory for most tracers, tracing core
has a special case for platforms w/o irqflags (which, by the way, has
become useless as of the commit above).
This patch restores the old behaviour, and thus brings the tracing
back on PPC32.
p.s.
The IRQSOFF_TRACER (which is the only tracer that requires IRQFLAGS
support) still depends on TRACE_IRQFLAGS_SUPPORT Kconfig symbol.
