[for-next][PATCH 1/2] powerpc/thp: tracing: Hide hugepage events under CONFIG_PPC_BOOK3S_64

[Steven Rostedt]

From: Steven Rostedt <rostedt@goodmis.org>

The events hugepage_set_pmd, hugepage_set_pud, hugepage_update_pmd and
hugepage_update_pud are only called when CONFIG_PPC_BOOK3S_64 is defined.
As each event can take up to 5K regardless if they are used or not, it's
best not to define them when they are not used. Add #ifdef around these
events when they are not used.

[for-next][PATCH 2/2] tracing: sched: Hide numa events under CONFIG_NUMA_BALANCING

[Steven Rostedt]

From: Steven Rostedt <rostedt@goodmis.org>

The events sched_move_numa, sched_stick_numa and sched_swap_numa are only
called when CONFIG_NUMA_BALANCING is configured. As each event can take up
to 5K of memory in text and meta data regardless if they are used or not,
they should not be defined when unused.

Move the #ifdef CONFIG_NUMA_BALANCING to hide these events as well.
