From 1e1c8b2cc37afb333c1829e8e0360321813bf220 Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 14 Jan 2020 07:14:40 +0000 Subject: powerpc/ptdump: don't entirely rebuild kernel when selecting CONFIG_PPC_DEBUG_WX Selecting CONFIG_PPC_DEBUG_WX only impacts ptdump and pgtable_32/64 init calls. Declaring related functions in asm/pgtable.h implies rebuilding almost everything. Move ptdump_check_wx() declaration in mm/mmu_decl.h Signed-off-by: Christophe Leroy Signed-off-by: Michael Ellerman Link: https://lore.kernel.org/r/bf34fd9dca61eadf9a134a9f89ebbc162cfd5f86.1578986011.git.christophe.leroy@c-s.fr --- arch/powerpc/mm/mmu_decl.h | 6 ++++++ arch/powerpc/mm/ptdump/ptdump.c | 2 ++ 2 files changed, 8 insertions(+) (limited to 'arch/powerpc/mm') diff --git a/arch/powerpc/mm/mmu_decl.h b/arch/powerpc/mm/mmu_decl.h index 8e99649c24fc..7097e07a209a 100644 --- a/arch/powerpc/mm/mmu_decl.h +++ b/arch/powerpc/mm/mmu_decl.h @@ -181,3 +181,9 @@ void mmu_mark_rodata_ro(void); static inline void mmu_mark_initmem_nx(void) { } static inline void mmu_mark_rodata_ro(void) { } #endif + +#ifdef CONFIG_PPC_DEBUG_WX +void ptdump_check_wx(void); +#else +static inline void ptdump_check_wx(void) { } +#endif diff --git a/arch/powerpc/mm/ptdump/ptdump.c b/arch/powerpc/mm/ptdump/ptdump.c index 2f9ddc29c535..4af0d5d9589e 100644 --- a/arch/powerpc/mm/ptdump/ptdump.c +++ b/arch/powerpc/mm/ptdump/ptdump.c @@ -24,6 +24,8 @@ #include #include +#include + #include "ptdump.h" /* -- cgit v1.2.3-59-g8ed1b
