[PATCH 18/46] entry, lto: Mark raw_irqentry_exit_cond_resched() as __visible

[Jiri Slaby (SUSE)]

From: Andi Kleen <ak@xxxxxxxxxxxxxxx>

Symbols referenced from assembler (either directly or e.f. from
DEFINE_STATIC_KEY()) need to be global and visible in gcc LTO because
they could end up in a different object file than the assembler. This
can lead to linker errors without this patch.

So mark raw_irqentry_exit_cond_resched() as __visible.
