Extending the kernel parameters to a 2048 bytes for
boot protocol >=2.02 of i386, ia64 and x86_64 architectures for
linux-2.6.18-rc4-mm2.
Current implementation allows the kernel to receive up to
255 characters from the bootloader. 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.
EDD issue was fixed recently by H. Peter Anvin, please add this
to mm so more problems may be found.
