Patch file

In some systems grub fails to load the rootfs.cpio as an initrd if it is too large.

On the system I am currently testing a 61MB file load successfully while a 174MB file does not.  With the larger file grub outputs an out of memory error.  The attached patch file allows the system to boot successfully.

Dr I J Ormshaw, All,

This is a grub limitation, so please work with grub upstream to lift that
limitation. Once they have accepted a fix, then we can see whether we can
backport it or not.

Regards,
Yann E. MORIN.
