From 2382705f22c1436a153800cf6051b08f0ea14838 Mon Sep 17 00:00:00 2001 From: zijun_hu Date: Fri, 7 Oct 2016 16:59:24 -0700 Subject: mm/nobootmem.c: remove duplicate macro ARCH_LOW_ADDRESS_LIMIT statements Fix the following bugs: - the same ARCH_LOW_ADDRESS_LIMIT statements are duplicated between header and relevant source - don't ensure ARCH_LOW_ADDRESS_LIMIT perhaps defined by ARCH in asm/processor.h is preferred over default in linux/bootmem.h completely since the former header isn't included by the latter Link: http://lkml.kernel.org/r/e046aeaa-e160-6d9e-dc1b-e084c2fd999f@zoho.com Signed-off-by: zijun_hu Cc: Ingo Molnar Signed-off-by: Andrew Morton Signed-off-by: Linus Torvalds --- include/linux/bootmem.h | 9 +++++---- 1 file changed, 5 insertions(+), 4 deletions(-) (limited to 'include/linux/bootmem.h') diff --git a/include/linux/bootmem.h b/include/linux/bootmem.h index f9be32691718..962164d36506 100644 --- a/include/linux/bootmem.h +++ b/include/linux/bootmem.h @@ -7,6 +7,7 @@ #include #include #include +#include /* * simple boot-time physical memory area allocator. @@ -119,6 +120,10 @@ extern void *__alloc_bootmem_low_node(pg_data_t *pgdat, #define BOOTMEM_LOW_LIMIT __pa(MAX_DMA_ADDRESS) #endif +#ifndef ARCH_LOW_ADDRESS_LIMIT +#define ARCH_LOW_ADDRESS_LIMIT 0xffffffffUL +#endif + #define alloc_bootmem(x) \ __alloc_bootmem(x, SMP_CACHE_BYTES, BOOTMEM_LOW_LIMIT) #define alloc_bootmem_align(x, align) \ @@ -180,10 +185,6 @@ static inline void * __init memblock_virt_alloc_nopanic( NUMA_NO_NODE); } -#ifndef ARCH_LOW_ADDRESS_LIMIT -#define ARCH_LOW_ADDRESS_LIMIT 0xffffffffUL -#endif - static inline void * __init memblock_virt_alloc_low( phys_addr_t size, phys_addr_t align) { -- cgit v1.2.3
