From 54effa653246c35997f5e990e0134be5be09f9d1 Mon Sep 17 00:00:00 2001 From: Quentin Perret Date: Wed, 3 Feb 2021 14:19:30 +0000 Subject: [PATCH] asm-generic: export: Stub EXPORT_SYMBOL with __DISABLE_EXPORTS It is currently possible to stub EXPORT_SYMBOL() macros in C code using __DISABLE_EXPORTS, which is necessary to run in constrained environments such as the EFI stub or the decompressor. But this currently doesn't apply to exports from assembly, which can lead to somewhat confusing situations. Consolidate the __DISABLE_EXPORTS infrastructure by checking it from asm-generic/export.h as well.
