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
