Currently kexec hard code X86_64_KERNEL_TEXT_SIZE to 512M. With kASLR enabled (CONFIG_RANDOMIZED_BASE=y), kernel image base offset could be randomized from 0 to 1GB and kexec-tools fails to get kernel virtual address from /proc/kcore when the offset is >512M. Now extend X86_64_KERNEL_TEXT_SIZE to 1GB to adapt kASLR.
