This function was marked EXPORT_SYMBOL_GPL -because at the time the patch was submitted, sme_me_mask was marked -EXPORT_SYMBOL_GPL. - -Commit 87df26175e67 ("x86/mm: Unbreak modules that rely on external -PAGE_KERNEL availability") changed sme_me_mask variable from -EXPORT_SYMBOL_GPL to EXPORT_SYMBOL, allowing external modules the ability -to build with CONFIG_AMD_MEM_ENCRYPT=y. Now, however, with sev_active() -no longer an inline function and marked as EXPORT_SYMBOL_GPL, external -modules that use the DMA API are once again broken in 4.15. Since the DMA -API is meant to be used by external modules, this needs to be changed. - -Change the sme_active() and sev_active() functions from EXPORT_SYMBOL_GPL -to EXPORT_SYMBOL. - -Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> -Signed-off-by: Thomas Gleixner <tglx@linutronix.de> -Cc: Borislav Petkov <bp@alien8.de> -Cc: Brijesh Singh <brijesh.singh@amd.com> -Link: https://lkml.kernel.org/r/20171215162011.14125.7113.stgit@tlendack-t1.amdoffice.net -Signed-off-by: Sudheesh Mavila <sudheesh.mavila@amd.com> ---- - arch/x86/mm/mem_encrypt.c | 4 ++-- - 1 file changed, 2 insertions(+), 2 deletions(-) - -diff --git a/arch/x86/mm/mem_encrypt.c b/arch/x86/mm/mem_encrypt.c -index 6d59032..5b023f2 100755 ---- a/arch/x86/mm/mem_encrypt.c -+++ b/arch/x86/mm/mem_encrypt.c -@@ -406,13 +406,13 @@ bool sme_active(void) - { - return sme_me_mask && !sev_enabled; - } --EXPORT_SYMBOL_GPL(sme_active); -+EXPORT_SYMBOL(sme_active); - - bool sev_active(void) - { - return sme_me_mask && sev_enabled; - } --EXPORT_SYMBOL_GPL(sev_active); -+EXPORT_SYMBOL(sev_active); - - static const struct dma_map_ops sev_dma_ops = { - .alloc = sev_alloc, --- -2.7.4 - |
