When "kernelcore" boot option is specified, kernel can't boot up on ia64 because of an infinite loop. In addition, the parsing code can be handled in an architecture-independent manner.
This patch patches uses common code to handle the kernelcore= parameter. It is only available to architectures that support arch-independent zone-sizing (i.e. define CONFIG_ARCH_POPULATES_NODE_MAP). Other architectures will ignore the boot parameter. This effectively removes the following arch-specific patches; ia64-specify-amount-of-kernel-memory-at-boot-time.patch ppc-and-powerpc-specify-amount-of-kernel-memory-at-boot-time.patch x86_64-specify-amount-of-kernel-memory-at-boot-time.patch x86-specify-amount-of-kernel-memory-at-boot-time.patch Signed-off-by: Yasunori Goto <[EMAIL PROTECTED]> Acked-by: Mel Gorman <[EMAIL PROTECTED]> Acked-by: Andy Whitcroft <[EMAIL PROTECTED]> --- arch/i386/kernel/setup.c | 1 - arch/ia64/kernel/efi.c | 2 -- arch/powerpc/kernel/prom.c | 1 - arch/ppc/mm/init.c | 2 -- arch/x86_64/kernel/e820.c | 1 - include/linux/mm.h | 1 - mm/page_alloc.c | 4 +++- 7 files changed, 3 insertions(+), 9 deletions(-) Index: kernelcore/arch/ia64/kernel/efi.c =================================================================== --- kernelcore.orig/arch/ia64/kernel/efi.c 2007-04-24 15:09:37.000000000 +0900 +++ kernelcore/arch/ia64/kernel/efi.c 2007-04-24 15:25:22.000000000 +0900 @@ -423,8 +423,6 @@ efi_init (void) mem_limit = memparse(cp + 4, &cp); } else if (memcmp(cp, "max_addr=", 9) == 0) { max_addr = GRANULEROUNDDOWN(memparse(cp + 9, &cp)); - } else if (memcmp(cp, "kernelcore=",11) == 0) { - cmdline_parse_kernelcore(cp+11); } else if (memcmp(cp, "min_addr=", 9) == 0) { min_addr = GRANULEROUNDDOWN(memparse(cp + 9, &cp)); } else { Index: kernelcore/arch/i386/kernel/setup.c =================================================================== --- kernelcore.orig/arch/i386/kernel/setup.c 2007-04-24 15:29:20.000000000 +0900 +++ kernelcore/arch/i386/kernel/setup.c 2007-04-24 15:29:39.000000000 +0900 @@ -195,7 +195,6 @@ static int __init parse_mem(char *arg) return 0; } early_param("mem", parse_mem); -early_param("kernelcore", cmdline_parse_kernelcore); #ifdef CONFIG_PROC_VMCORE /* elfcorehdr= specifies the location of elf core header Index: kernelcore/arch/powerpc/kernel/prom.c =================================================================== --- kernelcore.orig/arch/powerpc/kernel/prom.c 2007-04-24 15:04:47.000000000 +0900 +++ kernelcore/arch/powerpc/kernel/prom.c 2007-04-24 15:30:25.000000000 +0900 @@ -431,7 +431,6 @@ static int __init early_parse_mem(char * return 0; } early_param("mem", early_parse_mem); -early_param("kernelcore", cmdline_parse_kernelcore); /* * The device tree may be allocated below our memory limit, or inside the Index: kernelcore/arch/ppc/mm/init.c =================================================================== --- kernelcore.orig/arch/ppc/mm/init.c 2007-04-24 15:04:47.000000000 +0900 +++ kernelcore/arch/ppc/mm/init.c 2007-04-24 15:30:56.000000000 +0900 @@ -214,8 +214,6 @@ void MMU_setup(void) } } -early_param("kernelcore", cmdline_parse_kernelcore); - /* * MMU_init sets up the basic memory mappings for the kernel, * including both RAM and possibly some I/O regions, Index: kernelcore/arch/x86_64/kernel/e820.c =================================================================== --- kernelcore.orig/arch/x86_64/kernel/e820.c 2007-04-24 15:04:47.000000000 +0900 +++ kernelcore/arch/x86_64/kernel/e820.c 2007-04-24 15:34:02.000000000 +0900 @@ -604,7 +604,6 @@ static int __init parse_memopt(char *p) return 0; } early_param("mem", parse_memopt); -early_param("kernelcore", cmdline_parse_kernelcore); static int userdef __initdata; Index: kernelcore/include/linux/mm.h =================================================================== --- kernelcore.orig/include/linux/mm.h 2007-04-24 15:09:37.000000000 +0900 +++ kernelcore/include/linux/mm.h 2007-04-24 15:35:52.000000000 +0900 @@ -1051,7 +1051,6 @@ extern unsigned long find_max_pfn_with_a extern void free_bootmem_with_active_regions(int nid, unsigned long max_low_pfn); extern void sparse_memory_present_with_active_regions(int nid); -extern int cmdline_parse_kernelcore(char *p); #ifndef CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID extern int early_pfn_to_nid(unsigned long pfn); #endif /* CONFIG_HAVE_ARCH_EARLY_PFN_TO_NID */ Index: kernelcore/mm/page_alloc.c =================================================================== --- kernelcore.orig/mm/page_alloc.c 2007-04-24 15:09:37.000000000 +0900 +++ kernelcore/mm/page_alloc.c 2007-04-24 16:00:21.000000000 +0900 @@ -3728,6 +3728,9 @@ int __init cmdline_parse_kernelcore(char return 0; } + +early_param("kernelcore", cmdline_parse_kernelcore); + #endif /* CONFIG_ARCH_POPULATES_NODE_MAP */ /** -- Yasunori Goto - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
