PATCH 1/1 x86 Boot enhancements, vmlinux.lds 2/9

Linus, please apply.

This patch corrects the vmlinux so it correctly reports the physical load address of the kernel at 1MB, and the actual kernel entry point. This is done with a small change to the linker script and removal of the incorrect command line linker entry point specification.
