1. KERNEL_CRASH_DUMP should depends on KERNEL_PROC_KCORE (kexec use it) 2. select crashkernel mem size by totalmem mem <= 256M disable crashkernel by default mem >= 4G use 256M for crashkernel mem >= 8G use 512M for crashkernel default use 128M 3. set BOOT_IMAGE in kdump.init 4. resolve a "Unhandled rela relocation: R_X86_64_PLT32" error Tested on x86_64 Signed-off-by: Chen Minqiang <ptpt52@gmail.com>
