From c4028fa2daa059ac9231ab3a4f57cbae814b3625 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Wed, 21 Aug 2019 10:13:32 +0000 Subject: [PATCH] powerpc/mm: drop #ifdef CONFIG_MMU in is_ioremap_addr() powerpc always selects CONFIG_MMU and CONFIG_MMU is not checked anywhere else in powerpc code. Drop the #ifdef and the alternative part of is_ioremap_addr() Fixes: 9bd3bb6703d8 ("mm/nvdimm: add is_ioremap_addr and use that to check ioremap address") Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/de395e444fb8dd7a6365c3314d78e15ebb3d7d1b.1566382245.git.christophe.leroy@c-s.fr --- arch/powerpc/include/asm/pgtable.h | 4 ---- 1 file changed, 4 deletions(-) diff --git a/arch/powerpc/include/asm/pgtable.h b/arch/powerpc/include/asm/pgtable.h index 4053b2ab427c..0e4ec8cc37b7 100644 --- a/arch/powerpc/include/asm/pgtable.h +++ b/arch/powerpc/include/asm/pgtable.h @@ -157,13 +157,9 @@ static inline bool pgd_is_leaf(pgd_t pgd) #define is_ioremap_addr is_ioremap_addr static inline bool is_ioremap_addr(const void *x) { -#ifdef CONFIG_MMU unsigned long addr = (unsigned long)x; return addr >= IOREMAP_BASE && addr < IOREMAP_END; -#else - return false; -#endif } #endif /* CONFIG_PPC64 */ -- 2.30.2
