In commit 185be15143aa ("x86/mm: Remove set_pages_x() and set_pages_nx()"),
the wrappers were removed as they did not provide a real benefit over
set_memory_x() and set_memory_nx(). This change causes a problem because
the wrappers were exported, but the underlying routines were not. As a
result, external modules that used the wrappers would need to recreate
a significant part of memory management.Signed-off-by: Larry Finger <[email protected]> Cc: Christoph Hellwig <[email protected]> Cc: Peter Zijlstra (Intel) <[email protected]> Fixes: 185be15143aa ("x86/mm: Remove set_pages_x() and set_pages_nx()") Cc: Ingo Molnar <[email protected]> --- v2 - Subject was messed up --- arch/x86/mm/pageattr.c | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/x86/mm/pageattr.c b/arch/x86/mm/pageattr.c index 0d09cc5aad61..755867fc7c19 100644 --- a/arch/x86/mm/pageattr.c +++ b/arch/x86/mm/pageattr.c @@ -1885,6 +1885,7 @@ int set_memory_x(unsigned long addr, int numpages) return change_page_attr_clear(&addr, numpages, __pgprot(_PAGE_NX), 0); } +EXPORT_SYMBOL(set_memory_x); int set_memory_nx(unsigned long addr, int numpages) { @@ -1893,6 +1894,7 @@ int set_memory_nx(unsigned long addr, int numpages) return change_page_attr_set(&addr, numpages, __pgprot(_PAGE_NX), 0); } +EXPORT_SYMBOL(set_memory_nx); int set_memory_ro(unsigned long addr, int numpages) { -- 2.23.0
