[PATCH] x86_64: 2048-byte command line

Browse Source 
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.
