Re: [PATCH] kexec/kdump and kdb

["jidong xiao" <jidong.xiao@xxxxxxxxx>]

Hi, Dan

  I checked the mail archives of kdb mail list, and found some time
back you submitted following patch:

  http://www.mail-archive.com/kdb@xxxxxxxxxxx/msg01358.html

  I am interested in this topic, I have read through your patch and
attempt to apply your patch, but before that I have several questions
about it.

  1. As you mentioned, "There are a few issues with this patch", what
do you mean by this? What issue will I encounter if I apply this
patch?
  2. At the same time you said it is supported only for x86_64, now I
am trying to enhance it to include the support for i386, but not sure
what exactly shall I do, I saw your patch only changes one x86_64
specific file, that is arch/x86_64/kernel/crash.c, you extracted
halt_current_cpu() from crash_nmi_callback(), it seems
arch/i386/kernel/crash.c also includes this function, and the code
there is very similiar, so can I say the only thing I need to do is
make the similiar change in this file?

Thanks
Jason Xiao
