Decompressing Linux... Parsing ELF... Performing relocations... 32-bit relocation outside of kernel! These kconfig options are enabled: CONFIG_RANDOMIZE_BASE=y CONFIG_RANDOMIZE_BASE_MAX_OFFSET=0x40000000 Before digging further, we'd like to ask for a quick answer that whether they've been fixed by some commit in current mainline kernel? Thanks, Fengguang
