Re: [Crash-utility] ARM support for CONFIG_SPARSEMEM:(wasRe:DDimage)

>>>But it only happens when I use KDUMP format instead of
NETDUMP_ELF32.
I cannot reconfirm this. Please forget about it.
Yes, that's right -- the old NETDUMP_ELF32 format only contained one PT_LOAD
segment, so you'll have to make the minor adjustments to make it KDUMP_ELF32.
I forgot to mention one thing. I had to remove the following line
from
symbol.c as my target is non-SMP
1413: lm->mod_percpu = ULONG(modbuf + OFFSET(module_percpu));
I hope you will find a better way.

Although I don't see the module.percpu member surrounded by #ifdef CONFIG_SMP
in the upstream or older kernels. What does the module structure look like in
your kernel sources?
