From d9e5c3e9e75162f845880535957b7fd0b4637d23 Mon Sep 17 00:00:00 2001 From: Kevin Hao Date: Tue, 29 Mar 2022 16:57:09 +0800 Subject: [PATCH] powerpc: Export mmu_feature_keys[] as non-GPL When the mmu_feature_keys[] was introduced in the commit c12e6f24d413 ("powerpc: Add option to use jump label for mmu_has_feature()"), it is unlikely that it would be used either directly or indirectly in the out of tree modules. So we exported it as GPL only. But with the evolution of the codes, especially the PPC_KUAP support, it may be indirectly referenced by some primitive macro or inline functions such as get_user() or __copy_from_user_inatomic(), this will make it impossible to build many non GPL modules (such as ZFS) on ppc architecture. Fix this by exposing the mmu_feature_keys[] to the non-GPL modules too.
