[PATCH 15/46] x86/xen, lto: Mark xen_vcpu_stolen() as __visible

["Jiri Slaby (SUSE)" <jirislaby@xxxxxxxxxx>]

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 xen_vcpu_stolen() as __visible.
