[Qemu-devel] [PATCH] Remove restriction that prevents bootimg elf64 images

[Anatol Pomozov]

It is possible to create a 64 bit elf image that has valid multiboot header.
qemu should be able to boot such images.

Tested with homemade 64bit OS - now it boots fine with 'qemu -kernel'
and as a grub image.
