Peter Anvin" <hpa@...or.com>, Andrew Morton <akpm@...ux-foundation.org> Cc: David Miller <davem@...emloft.net>, Benjamin Herrenschmidt <benh@...nel.crashing.org>, Linus Torvalds <torvalds@...ux-foundation.org>, Johannes Weiner <hannes@...xchg.org>, linux-kernel@...r.kernel.org, linux-arch@...r.kernel.org, Yinghai Lu <yinghai@...nel.org> Subject: [PATCH 06/22] bootmem, x86: Add weak version of reserve_bootmem_generic It will be used lmb_to_bootmem converting It is an wrapper for reserve_bootmem, and x86 64bit is using special one. Also clean up that version for x86_64. We don't need to take care of numa path for that, bootmem can handle it how Signed-off-by: Yinghai Lu <yinghai@...nel.org> --- arch/x86/mm/init_32.c | 6 ------ arch/x86/mm/init_64.c | 20 ++------------------ mm/bootmem.c | 6 ++++++ 3 files changed, 8 insertions(+), 24 deletions(-) diff --git a/arch/x86/mm/init_32.c b/arch/x86/mm/init_32.c index bca7909..90e0545 100644 --- a/arch/x86/mm/init_32.c +++ b/arch/x86/mm/init_32.c @@ -1069,9 +1069,3 @@ void mark_rodata_ro(void) #endif } #endif - -int __init reserve_bootmem_generic(unsigned long phys, unsigned long len, - int flags) -{ - return reserve_bootmem(phys, len, flags); -} diff --git a/arch/x86/mm/init_64.c b/arch/x86/mm/init_64.c index ee41bba..634fa08 100644 --- a/arch/x86/mm/init_64.c +++ b/arch/x86/mm/init_64.c @@ -799,13 +799,10 @@ void mark_rodata_ro(void) #endif +#ifndef CONFIG_NO_BOOTMEM int __init reserve_bootmem_generic(unsigned long phys, unsigned long len, int flags) { -#ifdef CONFIG_NUMA - int nid, next_nid; - int ret; -#endif unsigned long pfn = phys >> PAGE_SHIFT; if (pfn >= max_pfn) { @@ -821,21 +818,7 @@ int __init reserve_bootmem_generic(unsigned long phys, unsigned long len, return -EFAULT; } - /* Should check here against the e820 map to avoid double free */ -#ifdef CONFIG_NUMA - nid = phys_to_nid(phys); - next_nid = phys_to_nid(phys + len - 1); - if (nid == next_nid) - ret = reserve_bootmem_node(NODE_DATA(nid), phys, len, flags); - else - ret = reserve_bootmem(phys, len, flags); - - if (ret != 0) - return ret; - -#else reserve_bootmem(phys, len, flags); -#endif if (phys+len <= MAX_DMA_PFN*PAGE_SIZE) { dma_reserve += len / PAGE_SIZE; @@ -844,6 +827,7 @@ int __init reserve_bootmem_generic(unsigned long phys, unsigned long len, return 0; } +#endif int kern_addr_valid(unsigned long addr) { diff --git a/mm/bootmem.c b/mm/bootmem.c index 58c66cc..ee31b95 100644 --- a/mm/bootmem.c +++ b/mm/bootmem.c @@ -526,6 +526,12 @@ int __init reserve_bootmem(unsigned long addr, unsigned long size, } #ifndef CONFIG_NO_BOOTMEM +int __weak __init reserve_bootmem_generic(unsigned long phys, unsigned long len, + int flags) +{ + return reserve_bootmem(phys, len, flags); +} + static unsigned long __init align_idx(struct bootmem_data *bdata, unsigned long idx, unsigned long step) { -- 1.6.4.2 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
