Hi Dave,

Here is the final patch to make crash work on x86-64 for
2.6.14 kernel.

Please let me know, if you want me to re-work or cleanup.

Thanks,
Badari
 

Everything looks good, but unfortunately using "startup_64" won't
work as a qualifier.  The virtual address values changed between
2.6.10 and 2.6.11, but the head.S label change from "reach_long64"
to "startup_64" came later (I'm not sure when).

Note that 2.6.11 has this #define:

#define VMALLOC_START    0xffffc20000000000UL

but it still has this in head.S:

.code64
         .org 0x100
reach_long64:
        movq init_rsp(%rip),%rsp

So, the key will be to find a difference between 2.6.10 and
2.6.11's symbol contents.

Thanks,
