The patch titled Subject: compiler.h: add __visible has been removed from the -mm tree. Its filename was compilerh-add-__visible.patch This patch was dropped because it was merged into mainline or a subsystem tree ------------------------------------------------------ From: Andi Kleen <ak@xxxxxxxxxxxxxxx> Subject: compiler.h: add __visible gcc 4.6+ has support for a externally_visible attribute that prevents the optimizer from optimizing unused symbols away. Add a __visible macro to use it with that compiler version or later. This is used (at least) by the "Link Time Optimization" patchset.
