From 54d5999d98f2ab36ad71b9ef4d82cf5f399205f5 Mon Sep 17 00:00:00 2001 From: "Aneesh Kumar K.V" Date: Tue, 30 Apr 2013 20:26:08 +0000 Subject: [PATCH] powerpc: Fix build error for book3e We moved the definition of shift_to_mmu_psize and mmu_psize_to_shift out of hugetlbpage.c in patch "powerpc: New hugepage directory format". These functions are not related to hugetlbpage and we want to use them outside hugetlbpage.c We missed a definition for book3e when we moved these functions. Add similar functions to mmu-book3e.h Signed-off-by: Aneesh Kumar K.V Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/include/asm/mmu-book3e.h | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+) diff --git a/arch/powerpc/include/asm/mmu-book3e.h b/arch/powerpc/include/asm/mmu-book3e.h index 8bd560c5fe84..936db360790a 100644 --- a/arch/powerpc/include/asm/mmu-book3e.h +++ b/arch/powerpc/include/asm/mmu-book3e.h @@ -215,6 +215,7 @@ #define TLBILX_T_CLASS3 7 #ifndef __ASSEMBLY__ +#include extern unsigned int tlbcam_index; @@ -254,6 +255,23 @@ struct mmu_psize_def }; extern struct mmu_psize_def mmu_psize_defs[MMU_PAGE_COUNT]; +static inline int shift_to_mmu_psize(unsigned int shift) +{ + int psize; + + for (psize = 0; psize < MMU_PAGE_COUNT; ++psize) + if (mmu_psize_defs[psize].shift == shift) + return psize; + return -1; +} + +static inline unsigned int mmu_psize_to_shift(unsigned int mmu_psize) +{ + if (mmu_psize_defs[mmu_psize].shift) + return mmu_psize_defs[mmu_psize].shift; + BUG(); +} + /* The page sizes use the same names as 64-bit hash but are * constants */ -- 2.20.1
