Yinghai Lu 46cb27f516 x86: check range in reserve_early() ... Impact: cleanup one 32-bit system reports: BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000001c000000 (usable) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) DMI 2.0 present. last_pfn = 0x1c000 max_arch_pfn = 0x100000 kernel direct mapping tables up to 1c000000 @ 7000-c000 ..

The reason is init_pg_table is big enough, and zero range is called with init_memory_mapping/reserve_early(). So try to check the range in reserve_early() v2: fix the reversed compare Signed-off-by: Yinghai Lu <yinghai@kernel.org> Cc: nickpiggin@yahoo.com.au Cc: ink@jurassic.park.msu.ru Signed-off-by: Ingo Molnar <mingo@elte.hu>		2009-02-24 22:43:15 +01:00
