[PATCH] ia64/mm: fix a bad_page bug when crash kernel booting

2013-01-28 Thread Xishi Qiu
On ia64 platform, I set "crashkernel=1024M-:600M", and dmesg shows 128M-728M memory is reserved for crash kernel. Then "echo c > /proc/sysrq-trigger" to test kdump. When crash kernel booting, efi_init() will aligns the memory address in IA64_GRANULE_SIZE(16M), so 720M-728M memory will be dropped,
