Next: lib: vsprintf: optimised put_dec() for 32-bit machines
From: Benjamin Herrenschmidt on 6 Aug 2010 01:20 Right now, both the "memory" and "reserved" memblock_type structures have a "size" member. It represents the calculated memory size in the former case and is unused in the latter. This moves it out to the main memblock structure instead Signed-off-by: Benjamin Herrenschmidt <benh(a)kernel.crashing.org> --- arch/powerpc/mm/mem.c | 2 +- include/linux/memblock.h | 2 +- mm/memblock.c | 8 ++++---- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/arch/powerpc/mm/mem.c b/arch/powerpc/mm/mem.c index 52df542..f661f6c 100644 --- a/arch/powerpc/mm/mem.c +++ b/arch/powerpc/mm/mem.c @@ -301,7 +301,7 @@ void __init mem_init(void) swiotlb_init(1); #endif - num_physpages = memblock.memory.size >> PAGE_SHIFT; + num_physpages = memblock_phys_mem_size() >> PAGE_SHIFT; high_memory = (void *) __va(max_low_pfn * PAGE_SIZE); #ifdef CONFIG_NEED_MULTIPLE_NODES diff --git a/include/linux/memblock.h b/include/linux/memblock.h index 0fe6dd5..c9c7b0f 100644 --- a/include/linux/memblock.h +++ b/include/linux/memblock.h @@ -27,12 +27,12 @@ struct memblock_region { struct memblock_type { unsigned long cnt; - phys_addr_t size; struct memblock_region regions[MAX_MEMBLOCK_REGIONS+1]; }; struct memblock { phys_addr_t current_limit; + phys_addr_t memory_size; /* Updated by memblock_analyze() */ struct memblock_type memory; struct memblock_type reserved; }; diff --git a/mm/memblock.c b/mm/memblock.c index 81da635..5ae413e 100644 --- a/mm/memblock.c +++ b/mm/memblock.c @@ -49,7 +49,7 @@ void memblock_dump_all(void) return; pr_info("MEMBLOCK configuration:\n"); - pr_info(" memory.size = 0x%llx\n", (unsigned long long)memblock.memory.size); + pr_info(" memory size = 0x%llx\n", (unsigned long long)memblock.memory_size); memblock_dump(&memblock.memory, "memory"); memblock_dump(&memblock.reserved, "reserved"); @@ -123,10 +123,10 @@ void __init memblock_analyze(void) { int i; - memblock.memory.size = 0; + memblock.memory_size = 0; for (i = 0; i < memblock.memory.cnt; i++) - memblock.memory.size += memblock.memory.regions[i].size; + memblock.memory_size += memblock.memory.regions[i].size; } static long memblock_add_region(struct memblock_type *type, phys_addr_t base, phys_addr_t size) @@ -423,7 +423,7 @@ phys_addr_t __init __memblock_alloc_base(phys_addr_t size, phys_addr_t align, ph /* You must call memblock_analyze() before this. */ phys_addr_t __init memblock_phys_mem_size(void) { - return memblock.memory.size; + return memblock.memory_size; } phys_addr_t memblock_end_of_DRAM(void) -- 1.7.0.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo(a)vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/ |
