[PATCH] x86_64: 2048-byte command line
Current implementation allows the kernel to receive up to 255 characters from the bootloader. While the boot protocol allows greater buffers to be sent. In current environment, the command-line is used in order to specify many values, including suspend/resume, module arguments, splash, initramfs and more. 255 characters are not enough anymore. After edd issue was fixed, and dynammic kernel command-line patch was accepted, we can extend the COMMAND_LINE_SIZE without runtime memory requirements.
