MIPS: Export mm switching functions used by KVM

paulburton · paulburton · commit 6782f26c0d40 · 2019-02-05T11:44:44.000-08:00
KVM makes use of check_switch_mmu_context(), check_mmu_context() & get_new_mmu_context() which are no longer static inline functions in a header. As such they need to be exported for KVM to successfully build as a module, which was previously overlooked. Add the missing exports. Signed-off-by: Paul Burton <paul.burton@mips.com> Fixes: 4ebea49 ("MIPS: mm: Un-inline get_new_mmu_context") Fixes: 42d5b84 ("MIPS: mm: Unify ASID version checks")
