Increase kernel text size for x86_64

Hi all,

I cannot load a x86_64 kernel with kexec on 2.6.31; the error message is:

Can't find kernel text map area from kcore
Cannot load /boot/vmlinuz

Digging through the source I found a mismatch between the assumed
kernel text size; kexec has:

#define KERNEL_TEXT_SIZE  (40UL*1024*1024)

but on the kernel side we have:

include/asm/page_64_types.h:
#define KERNEL_IMAGE_SIZE   (512 * 1024 * 1024)

And, indeed, changing the definition in kexec-tools to the kernel one
fixed the problem.

Not sure if this has been reported before, if so please ignore
the noise.

Cheers,

Hannes
